Do you have any plans around Baldwin Place New York for the weekend? Maybe you and some friends and are taking the boat up to the lake. Maybe you’ll be having a lot of fun water skiing and doing a little fishing.

You got the boat all ready. It’s all gassed up. You packed lots of snacks and the cooler’s stocked – ready to go.

How about your tow vehicle? It has plenty of gas and you’ve even vacuumed it out, but is your auto maintenance up to date?

Stop and think. You’ll have some heavy traffic on your way out of town. Hilly terrain as you get to the lake. Some dirt roads – and it may be hot weather. And all the time you’re going to be towing around several thousand extra pounds.

That all adds up a lot of severe strain on your engine, brakes and transmission. Your transmission’s going to be working overtime, spending more time in lower gears. The internal transmission temperature is going to be much higher than normal. What’s a fun little blast to the lake for you is really severe duty for your transmission.

It’s important that you have enough transmission fluid. If you’re running low, the transmission will run to hot and won’t have the protection it needs to cope with the added stress of towing.

And if it’s time for a transmission service, you really should have it done at C&A Auto Service before your trip. Transmission fluid breaks down and gets dirty over time. Whether you have an automatic or manual transmission, you need to have it serviced on schedule to make sure it runs efficiently.

Automatic transmissions contain a maze of passages that the fluid has to pass through to keep it shifting smoothly. If you neglect transmission service, the passages can get clogged up and you start to have problems. Neglect your transmission for too long, and it can fail. Believe us – you don’t want to pay for a major transmission repair.

You know, most of us in Baldwin Place New York do a lot of our driving under severe conditions. Towing or hauling a big load is obvious, but there are lots of other things that constitute severe driving conditions. Things like short trips or driving in very hot or very cold weather. Also, dusty roads, city driving around Baldwin Place, and basically any driving that’s not at highway speeds or under ideal conditions is severe driving. We all need to think about whether or not we need to follow the severe service schedule.

So, consider going in for a full service oil change before you leave for the lake to make sure everything has been looked at. Ask for a trip inspection while you’re at it. Your Baldwin Place New York service technician at C&A Auto Service can check your belts and hoses and let you know if your brakes are in good shape.

Don’t forget the sunscreen. And to thank your Baldwin Place service technician, how about bringing him back a nice trout?

Tire Maintenance In jefferson valley

January 27th, 2010 by wado

With the recent focus in jefferson valley on improving fuel economy, we’ve been told how important it is to maintain our tire pressure.

Everyone in jefferson valley knows that tires wear out, but we all want to make them last as long as possible because they’re fairly expensive to replace. In addition to saving gas, properly inflated tires last longer. Under-inflated tires will wear out more quickly.

Some people in jefferson valley wonder if there is benefit to adding a few extra pounds of pressure when they fill up their tires. But actually, there isn’t. In fact, there are very good reasons not to over-inflate your tires. For one, the middle of the tread will wear unevenly because the full tread is not contacting the road properly. That also adversely affects your handling.

Come in and see us about tire maintenance for your Baldwin Place, New York vehicle.
C&A Auto Service

Baldwin Place, New York 10505
845-628-8472

Every vehicle in the jefferson valley area has a sticker on the driver’s side door jamb that tells you the manufacturer’s recommended tire pressure. This recommendation is an integral part of the vehicle’s suspension tuning. A lot of engineering actually goes into the recommended tire pressure, so it’s important to follow it.

What else do we need to know about tire maintenance? Tire rotation and balancing are very important. Let’s start with rotation. Because the front tires handle the brunt of turning forces, the shoulders of the front tires wear more quickly than the rear tires. We rotate the tires so that they all get to do some duty on the front and they’ll all wear evenly over their life.

For most vehicles, front tires are rotated to the rear and vice versa. Others recommend a cross rotational pattern. Some vehicles use an asymmetrical tire so those tires need to stay on either the right or left side – it’ll say which on the tire. Some high performance cars have asymmetrical tires and different sizes on the front and rear. These can’t be rotated at all. Your owner’s manual will have details for your car.

How often should you rotate your tires? Your owner’s manual will have a recommendation. Your service advisor at C&A Auto Service can do a visual inspection to let you know if it looks like it should be done. The interval is typically around 5,000 miles.

You know, some people don’t think new tires need to be balanced. What they aren’t taking into account is the wheel. Between the wheel and the tire – even a new tire – there’s enough variation to require balancing.

When you add the valve stem and tire pressure monitoring sensors required on new cars, balancing is definitely in order. When a tire’s out of balance, it’s actually hopping down the road. You’ll feel the vibration through the steering wheel if a front tire’s out of balance and through your seat if it’s a rear tire.

Proper wheel balance promotes tire life and increases safety. Historically, lead weights have been attached to the wheel to bring it into balance. Lead gives some environmental concern, so steel weights are starting to be substituted.

Also, always use the same size tire on an axle. Different size tires on the front or on the back can lead to some real handling problems. And tire manufacturers recommend that when you get two new tires, they be installed on the rear because that’s where you need the most traction to avoid spinning-out.

Fuel Filter Service in Baldwin Place New York

January 20th, 2010 by wado

There are a surprising number of small, inexpensive parts that can lead to expensive engine damage when they fail. It doesn’t seem right.

Fortunately a lot of those things can be taken care of in routine maintenance. They may not be easy to remember, because it is a long list, but your service center at C&A Auto Service can help you know what’s scheduled to be taken care of.

Some of us in Baldwin Place New York really don’t look forward to going in for an oil change and then getting a list of the other things the manufacturer recommends.

But automotive maintenance is all about prevention, and addressing small problems before they get big. Let’s take the fuel filter for example.

You may not know this but the median age for private vehicles on our Baldwin Place New York roads is over nine years. When cars get older, five years or so, they’ve accumulated a lot of dirt and rust in their gas tanks. If that dirt gets into the engine it can cause thousands of dollars worth of damage. So somewhere between that dirty gas tank and the price of a great vacation – is the lowly fuel filter: a very inexpensive part that doesn’t cost too much to replace. And your car’ll just run better too.

A clogged fuel filter can’t let enough fuel through. You might notice at first that your car is running fine around town, but struggles or sputters on the Baldwin Place New York freeway or when you accelerate. Enough fuel can’t get through to meet the demands of higher speed. If it gets bad enough your engine might just shut off or not start at all, which could be dangerous.

Some fuel filters have a bypass. When they get clogged, they allow dirty fuel to move around the filter element so dirt ends up in the engine. We’ve already talked about how expensive that can be.

The fuel filter is even very important for newer cars. The fuel is still dirty even if there isn’t rust in the tank. It’s just that the fuel filter will need to be changed more frequently as the vehicle gets older.

How often should you change your fuel filter? Check your owner’s manual. Your Baldwin Place New York service advisor at C&A Auto Service can tell you as well. It’s usually around thirty thousand miles or so. Ask if it’s time for a full fuel system cleaning as well. They often go hand in hand.

It’s good to know that your Baldwin Place New York service center has your back. When you’re motivated to maintain your vehicle’s performance and to reduce operating costs, you’ll think of C&A Auto Service as your ally – and maybe even your memory.

Baldwin Place Drivers Severe Service Maintenance Schedules

December 31st, 2009 by wado

Your vehicle manufacturer publishes two auto maintenance schedules. The regular schedule and the severe service schedule. It’d be wrong for us to tell you that everyone in mahopac always needs to follow the severe service schedule – but its wishful thinking to say that the regular schedule is always good enough for your sedan.

Contact C&A Auto Service to learn more about Severe Service Requirements for your sedan
You can find us at:
24 Rout 118
Baldwin Place, New York 10505
Or call us at 845-628-8472

At C&A Auto Service we’ll give you the definitions and explain the issues, and you can be the judge. Most manufactures list the following as severe conditions:

  • Most of your trips are less than four miles.
  • Most of your trips are less than 10 miles and outside temperatures are below freezing.
  • The engine is at low speed most of the time – not on the highway.
  • You operate your vehicle in dusty areas.
  • You regularly tow a trailer or carry heavy loads.
  • Driving in very hot or very cold weather.

So think about your typical week. Do you live a block from a New York freeway on-ramp and enjoy a non-stop commute to work in somers or jefferson valley? Or are you like the rest of us where 90% of our trips are on the severe service list?

The answer may be different at different times of the year and for the different drivers in your family. Think of the two service schedules as bookends. Let’s suppose your owner’s manual says the severe service oil change recommendation is 3,000 miles and the standard recommendation is 5,000 miles. You know that you need to change the oil somewhere between 3,000 and 5,000 miles. Look at your driving patterns and Baldwin Place road conditions and honestly evaluate which end of the spectrum you’re closer to.

If you have a job in a neighboring town such as yorktown or somers and most of your commute is freeway miles, you may choose the regular service schedule for your car. On the other hand, if you live within a few miles of work and only get on the highway a handful of times every month, something closer to the severe service schedule is more appropriate.

Now why is this so important? Moisture builds up in the engine oil from normal condensation. Short trips around mahopac or driving when it’s really cold means that the engine doesn’t heat up enough for the moisture to evaporate. The water in the oil leads to oil sludge that gums up your engine and doesn’t let the oil protect it as well. That’s why you need to change your oil more frequently – to get the sludge out before it causes problems.

Towing, heavy loads and very hot New York summer weather means that your engine and transmission will operate at higher temperatures and with more stress. The fluids will break down more quickly. Additives that clean and prevent corrosion will be depleted sooner. Dusty conditions, which may extend also to areas with high air pollution, mean that fluids will get dirty faster and that filters will plug up and won’t work right.

All of these things can lead to premature wear and repairs down the road. They’ll also hurt your fuel economy. If you want some personalized advice, talk with your honest C&A Auto Service service advisor. We can help you restore your vehicle to good working order and help you know the best schedule to follow. If you’re not sure, err on the side of protection.

What To Do In Case Of An Accident in mahopac

December 23rd, 2009 by wado

Screeching tires, crunching metal – it’s an accident! If you’ve ever been in a car accident in mahopac, even a minor one, you know how upsetting it can be. It’s hard to think straight and know what to do.

Let’s review what you should do in case of an accident:

When an accident occurs, you should always stop. Leaving the scene of an accident in Baldwin Place is considered a crime – even if it’s not your fault. And hit and run penalties are fairly severe, possibly resulting in steep fines, loss of your New York driver’s license or even jail time.

Your jurisdiction may require that you try to help someone who is injured by calling for help or performing first aid if you are able. Warn other somers and jefferson valley motorists by putting out flares, using your flashers or lifting your hood. Call mahopac emergency services as soon as possible. Tell the operator if medical or fire help is needed.

Always file a Baldwin Place police report. It’s tempting to skip this if everything seems to be ok. But without a police report, the other guy can say whatever he wants about the accident later, and you’ll not have an objective report to help defend yourself. Discuss the accident only with the police. Emotions are strong after an accident and we naturally want to talk about it – don’t. Never admit fault or guilt to anyone including the police officer. Sometimes we may feel at fault, but in the eyes of the law, the other guy is responsible.

Truthfully give the officer the facts: such as “I was going thirty miles an hour” not “I wasn’t speeding”. Remember, anything you say to the officer or anyone else can be used against you.

Also get the officer’s name and ID number and ask where you can get a copy of the accident report.

Get the facts on the driver and owner of the other vehicle:

  • Name
  • Address
  • Phone number
  • Date of birth
  • Driver’s license number and expiration
  • Insurance information

Also take down a description of the other Baldwin Place vehicle, license plate and vehicle identification number. Most New York auto insurance companies don’t record license plate numbers, so the VIN number is the best way to track the vehicle.

Ask witnesses, including passengers, to wait for the police. If they can’t wait, ask for contact information and request that they write a brief description of what they saw. If someone refuses to leave their name, write down their license plate number so the police can track them down later if necessary. Always call your insurance agent or your insurance company. Call or see a physician if you think you may have been injured. For vehicle repairs, call C&A Auto Service at 845-628-8472

Contact C&A Auto Service to learn more about what do do in case of an auto accident.

Timing Belt Replacement in Baldwin Place

December 15th, 2009 by wado

Today we want to talk about timing belts. They’re something that many Baldwin Place drivers don’t know much about and yet your vehicle won’t run if it’s broken – and it could cause many thousands of dollars damage if it does break. A broken timing belt is usually a tale of woe. Even though timing belt replacement is scheduled in the owner’s manual, it’s not the kind of thing that most mahopac car owners remember because it’s not well understood.

Let’s review what a timing belt does. As you know, the engine’s power is generated in the cylinders. A piston rides up and down in the cylinder. During the first down stroke, an intake valve at the top of the cylinder opens and air and fuel is drawn into the cylinder. Then the piston returns to the top, compressing the fuel and air mix. At the top, the spark plug fires, igniting the fuel pushing the piston down in the power stroke. As the piston once again returns up in the final stroke of the cycle, an exhaust valve opens at the top of the cylinder and the exhaust is pushed out. The timing belt is what coordinates the opening and closing of the intake and exhaust valves. It’s called a timing belt because the valves have to open and close at just the right time.

Now, not all yorktown and somers vehicles have timing belts. Some have timing chains. Like the name implies, they use a chain rather than a belt to perform the function. It used to be that most engines used timing chains, which are extremely durable. Manufacturers started using belts rather than chains to save money in the manufacturing process. So now we’re left with a component that can break. They sort of shifted the problem to us. There are two broad categories of engine design: interference and non-interference. If the timing belt on a non-interference engine breaks, the engine simply stops running. That could be very dangerous depending on where you are at the time, but it causes no internal engine damage.

Interference engines, on the other hand, will get real messed up when the timing belt breaks, because the valves will actually fall down into the path of the pistons. Things get chewed up when that happens and it’ll cost thousands to repair the engine.

So, what are the warning signs? Unfortunately, there really aren’t any. There aren’t tell-tale sounds. In some vehicles, a technician from C&A Auto Service may be able to see part of the belt for a visual inspection, but many have a cover that’s in the way. The reality is that if the belt slips even one notch, it might as well be broken for all the damage it’ll cause. There’s no middle ground.

So how can we avoid these problems? Simply replace the timing belt when your owner’s manual calls for it. It can be 60,000 miles; it might be 90,000 or 100,000 miles. The point is, if you have 60,000 or more miles, ask your C&A Auto Service service advisor right away if your manufacturer requires a timing belt replacement.

Contact C&A Auto Service to learn more about your car’s Timing Belt
You can find us at:
24 Rout 118
Baldwin Place, New York 10505
Or call us at 845-628-8472

Sometimes you can go quite a while without a failure, but we’ve seen them happen within a couple of oil changes of being due. It’s not worth the risk.

What does it cost to replace a timing belt in somers or jefferson valley? Well, that really depends on what kind of car you have. I can tell you that it’s usually not very easy to get to the timing belt – you often have to remove some accessories to get at it. It isn’t a cheap procedure, but it’s a fraction of what it could cost to repair the damage caused by a failure.

At C&A Auto Service we’re all about trying to prevent costly repairs, keeping you and your passengers safe and increasing your driving enjoyment. Thanks to AutoNetTV for their great auto video tips.

What Baldwin Place Automotive Service Consumers Should Know

December 10th, 2009 by wado

There are some things mahopac consumers should know about Baldwin Place automotive service and repair. First and foremost, C&A Auto Service cares about you and your family’s safety. And we really appreciate your business. C&A Auto Service in Baldwin Place wants to build a trusting relationship that becomes the foundation for a mutually beneficial experience for years to come.

Building on that foundation, there are some things that would help you understand the auto service and repair business better. First, it can be really hard to fix cars. The days of shade tree mechanics are long gone. The majority of automotive systems are computerized. It takes a lot of training and very expensive equipment to diagnose and repair modern vehicles. The technicians that work for C&A Auto Service need extensive computer training – not just how to run the diagnostic systems, but also searching for the right parts, networking with other technicians to help them with a difficult problem and pulling together a job order that makes sure that each step of the process is addressed.

The threshold for getting started as a technician gets higher all the time and there is a huge commitment to on-going training every year. This training takes time and money. It contributes to business overhead. The average yorktown or somers driver may not realize the business and environmental regulations C&A Auto Service must comply with. Of course that costs money too. Like any business, overhead is a big factor.

When you go into a mahopac restaurant you don’t value the meal by what the food would cost at the grocery store. The restaurant has rent, wages, insurance, taxes, utilities, professional fees, equipment, supplies – you get the picture. The restaurant has to charge enough to not only pay for the ingredients, but for all these other things as well while making enough profit to remain in business. If you value the meal and are satisfied with your dining experience, you’ll come back and tell your friends.

It’s the same for C&A Auto Service. The value of its service is not the cost of the parts they replace, but in your satisfaction with the results. If they deliver a good product at a fair price, Baldwin Place customers are happy to see them succeed as a New York automotive business.

Contact C&A Auto Service to learn more about our extensive auto service training.
You can find us at:
24 Rout 118
Baldwin Place, New York 10505
Or call us at 845-628-8472

Your Baldwin Place service center loves to see its customers whenever they come in, but they would much rather see them three or four times a year for routine maintenance than once a year on a tow truck. They want to work together with you to avoid breakdowns. Tell your mahopac area friends and family to go in for their scheduled maintenance too. That lowers the service center’s marketing costs and helps keep its labor rates down. That’s good for everyone.

C&A Auto Service appreciates this great review of automotive service from AutoNetTV.

Nitrogen Fill For Tires in Baldwin Place New York

December 2nd, 2009 by wado

So, everyone in the Baldwin Place New York area knows how great helium is – you know, party balloons, squeaky voices. But a lot of people around Baldwin Place still haven’t heard about the benefits of nitrogen in your tires, and how it can help your tires. Here’s some great advice from AutoNetTV, brought to you by C&A Auto Service.

Nitrogen has actually been around for a long time in the Baldwin Place New York commercial sector, but it’s just starting to catch on for private vehicles in the 10505 zip code area.

Why nitrogen in your tires? Air is air, right? Actually, it turns out there is a difference.

Contact C&A Auto Service to learn more about nitrogen in your tires
You can find us at:
24 Rout 118
Baldwin Place, New York 10505
Or call us at 845-628-8472

The heart of the matter is maintaining proper tire inflation. When your tires are properly inflated, they last longer, handle better and more safely, and save you money at the gas pump.

The problem is that tires filled in Baldwin Place with regular air can lose a pound and a half of air pressure every month. This just happens as the oxygen in the tire seeps out. So if you don’t check your pressure for a month or two, well, you can be significantly low – low enough to actually affect your handling, shorten tire life and waste money at the fuel pump.

How does nitrogen help? Regular air contains about 78% nitrogen. Nitrogen is the largest molecule in air. It’s dry and non-flammable. Air also contains 21% oxygen, which is smaller and seeps out of the tire three to four times faster than nitrogen.

So, a tire filled with nitrogen at C&A Auto Service will take about six months to lose as much pressure as regular air does in just one month. So it’s more forgiving for those who don’t check their pressure every week.

Also, when oxygen is at higher temperatures – like those inside your tire when you’ve been driving for awhile – it oxidizes the inside of your tire. Getting the oxygen out of your tire means that it’ll last longer.

Who’s using nitrogen? Well, let’s start with NASCAR and Indy. These racers like nitrogen’s ability to maintain consistent tire pressure and reduce tire temperatures under very demanding conditions. The US government requires all commercial aircraft to have nitrogen in their tires. NASA and the US Military use nitrogen. The mining industry has been filling those “humongous” tires with nitrogen for years. And semi trucks and trailers are starting to use nitrogen extensively.

You may have heard some detractors of nitrogen. But the studies and white papers from tire and vehicle manufacturers demonstrate that the technology really works.

In fact, a prominent consumer research group did a study where they filled some tires with air and some with nitrogen and stacked them outside for a year. They observed that the nitrogen filled tires did hold their pressure better, but they couldn’t see the economic benefit. But that particular test has very little to do with the real world. Most tires are actually holding up cars and they also get driven around and do a lot of work. So if nitrogen helps them last longer, saves gas and gives safer handling, it’s worth considering.

E-85 Fuel Safety Advice From C&A Auto Service

November 27th, 2009 by wado

Today at C&A Auto Service we want to talk with you about a very important safety issue. This automotive safety warning is coming from a very unusual source: fire fighting experts. You’ve probably heard of E-85 gasoline being offered in the mahopac area. Some newer vehicle models are specifically built to run on E-85 – the rest are not.

Does your vehicle use E-85 gasoline? Bring it down to C&A Auto Service at 24 Rout 118 in Baldwin Place, New York 10505 to find out, or give us a call to make an appointment by calling 845-628-8472.

E-85 gasoline has been developed to fight air pollution and reduce oil consumption. E-85 fuel is a mix of 15% ethanol, a grain-base alcohol, and 85% gasoline. So-called Flex-Fuel vehicles are designed to use either normal gasoline or E-85 gas. The result is lower harmful exhaust emissions to our local mahopac community.

All gas engines can run with up to 10% ethanol and in fact a lot of gasoline sold in the Baldwin Place New York area does contain some ethanol. The problem comes when well meaning people without Flex Fuel certified vehicles put E-85 into the tank.

At a 15% concentration, the potential for problems arises. Because of the chemical differences between ethanol and gasoline, special seals and gaskets are needed for Flex Fuel vehicles in Baldwin Place New York. In a normal engine, the ethanol in E-85 gas will eat away important seals and gaskets. This leads to gas and oil leaks.

You can imagine the fire hazard caused by leaking gasoline. Fire fighting experts caution consumers to only use E-85 if they know they vehicle is certified to handle it. They expect vehicle fires to increase because of using the wrong fuel in non-Flex Fuel vehicles.

So are people who don’t have a Flex Fuel vehicle but use E-85 to help the environment actually putting themselves at risk? Yes. In fact, service and repair centers in Baldwin Place New York are being warned to purchase fire extinguishers that use the special foam needed to extinguish ethanol fires as a precaution in case starting-up an ethanol damaged engine leads to a fire.

Obviously, this isn’t something you want to have in your Baldwin Place New York garage at home, either. If you have a Flex-Fuel certified vehicle, feel free to protect the environment by using E-85 gasoline. If not – please do not use E-85 in an engine that’s designed to run on unleaded gasoline only. At C&A Auto Service we are concerned about your safety. If you have questions or want to find out how to determine if your vehicle can safely use E-85, go to www.e85fuel.com for more resources.

Drive Train – What You Need to Know In Baldwin Place

November 18th, 2009 by

One Baldwin Place automotive service issue that doesn’t get much attention is driveline service. Drivelines don’t get talked about very much around Baldwin Place, but they’re very important. First let’s define what the driveline is:

Taking a small step back, the power plant is comprised of the engine and transmission. The driveline starts there and includes all of the components that transfer power from the transmission to the wheels.

That’s not really a lot of components, but they handle the full force of the engine. Without the driveline you’re not moving. So we need to take good care of it. The driveline components differ depending on whether your vehicle has front wheel drive, rear wheel drive, all wheel drive or four wheel drive. For purposes of our discussion, we’re going to have to over simplify a bit.

If you are ready to have your drive train looked at, give us a call:
C&A Auto Service
24 Rout 118
Baldwin Place, New York 10505
Call Us at 845-628-8472

Let’s start with front wheel drive. The point where the transmission stops and the driveline begins is a little blurred with front wheel drive because the transaxle houses both the transmission function and the differential function. The half shafts that send power to each front wheel, come out of the transaxle. The shaft is connected to the wheel by a constant velocity, or CV, joint. The CV joint is protected from dirt and water by an airtight, flexible rubber boot.

So, driveline service would include properly servicing the transaxle and inspecting the CV boot to see if it’s torn or loose. If it is, it needs to be replaced and the CV joint inspected for damage. Repairs may be in order. Besides visual damage to the airtight CV boot, you might hear a clicking noise when turning. Recommended maintenance for the transaxle and CV joints will be spelled out in your owner’s manual or check with your Baldwin Place service advisor.

On to rear wheel drive. The driveline for a rear wheel drive vehicle starts with the driveshaft – that long tube that connects the transmission with the differential on the rear axle. Some vehicles in Baldwin Place have a two piece drive shaft. The shafts are connected to the transmission and the differential with big universal joints. You’ve probably heard the term ‘u-joints‘. These joints can wear out, just like the CV joints in front wheel drive vehicles. You may hear some clunking or feel a jolt when shifting into drive or reverse – if you do, get your driveline inspected.

The differential on the rear axle sends power out to each rear wheel through half shafts in the axle. The differential fluid needs to be drained periodically and replaced with clean fluid. When the seal on the end of the axel is damaged or leaks, the axel will need to be serviced. The routine maintenance item here is differential service. Be sure to check your owner’s manual or Baldwin Place service advisor for intervals.

Now let’s go on to all wheel drive. Remember that the difference between all wheel drive and four wheel drive is that an all wheel drive vehicle is essentially providing power to all of the wheels all of the time. The vehicle may be able to shift more of the power to the front or to the back depending on where you need traction. All wheel drive vehicles are designed to work well on dry pavement. Even some high-end sports cars from makers like Lamborghini and Porsche have all wheel drive.

Some all wheel drive vehicles are designed to work well off-road, but all hard-core rock crawlers are four wheel drive. These guys thrive in mud, sand, rocks and hills – but they don’t work well on dry pavement when they’re in four wheel drive. So they have the option to shift to rear wheel drive only on dry pavement.

Most all-wheel drive vehicles are very similar to front wheel drive when it comes to the front end. They also have a center differential that transfers power to the rear differential. Connecting it all is a shaft from the transaxle to the center differential and another from the center differential to the rear differential. So all of the normal front wheel drive service is required as well as service to the center and rear differentials.

Four wheel drive can be thought of as a rear wheel drive vehicle that can also send power to the front axle. There’s a transfer case in the middle of the vehicle that can be shifted to send power through a drive shaft to a differential on the front axle. So you need differential service for the front and rear differentials and for the transfer case as well.

The bottom line is that the maintenance schedules are in your owner’s manual. Your Baldwin Place service advisor can answer any questions you’ve got. If this is the first time you’ve heard some of this stuff – it’s time to ask someone at C&A Auto Service if any of it needs to be done now.
