Drive Train Service in Louisville at American Brake Centers Inc.

The drive train in your vehicle includes all the components that transfer power from the transmission to the wheels. Those components differ depending on what type of vehicle you drive, namely, front-wheel drive, rear-wheel drive, all-wheel drive or four-wheel drive. The preventive maintenance your driveshaft needs will also differ by what type of vehicle you drive.

Let's start with front-wheel drive. In this vehicle, the transmission and the differential are combined in one component, known as the transaxle. The transaxle is connected to two half-shafts (axles), which are then connected to the wheels with a constant velocity (or CV) joint, which is protected by an airtight rubber boot.

American Brake Centers Inc. service for this type of driveline includes servicing the transaxle and inspecting the CV boot. If the boot is damaged, the CV joint will need to be inspected, and the boot will need to be replaced. If you hear a clicking noise in your wheel wells when you turn, you may have a damaged CV joint. A damaged CV joint should be replaced.

Rear-wheel drive vehicles generally have a transmission in the front of the car and the differential in the back. A driveshaft (it looks like a long tube) connects the transmission to the differential. Some vehicles may have a two-piece driveshaft, which are connected to the differential with universal joints or U-joints. Again, the differential is connected to two half-shafts that go out to the wheels.

American Brake Centers Inc. service on the drive train on a rear-wheel drive vehicle starts with servicing the differential. It will need its fluid drained and replaced regularly. The seals on the axles should also be inspected for wear or leaks. Leaking or damaged seals may mean the axle needs to be serviced as well. Also, U-joints can wear out. If you hear clunking or feel a jolt when you shift into drive or into reverse, it could indicate a driveline problem.

All-wheel drive vehicles provide power from the transmission to all of the wheels, instead of just to the front or rear. The advantage is that the vehicle can adapt to different driving conditions and transfer more power to the front or back wheels as needed. The disadvantages are that the driveline is more complicated, and the vehicle weighs slightly more.

Many all-wheel drive vehicles are based on a front-wheel drive set-up. They also have a differential in the rear and one in the center of the vehicle that allows power to transfer to the front and rear. A shaft runs from the transfer case to the center differential, and another from the center differential to the rear differential.

Servicing an all-wheel drive at American Brake Centers Inc. involves servicing ALL of the differentials and inspecting the joints and seals for wear, leaks or damage.

Four-wheel drive vehicles are rear-wheel drive vehicles that have an option to transfer power to the front wheels. In other words, they can be driven as either rear-wheel or four-wheel drive vehicles. These vehicles are specifically designed for the harsh driving conditions Louisville drivers encounter off-road. The driveline in a four-wheel drive vehicle is similar to that of an all-wheel drive vehicle. The center differential, however, is a transfer case. Maintenance requires servicing both of the differentials and the transfer case, as well as an inspection of the joints and seals.

Louisville auto owners would be wise to check with their owner's manual for recommendations on how often to service their vehicle drive train. It's also good auto advice to check with your friendly and knowledgeable American Brake Centers Inc. service advisor as well. You may live in an area in KY where weather or driving conditions require more frequent servicing of the drive train.


Good car care at American Brake Centers Inc. in Louisville always includes taking care of your driveline. Without it, your vehicle becomes a very large paperweight.

Motor Oil?The Synthetic Advantage (Synthetic oil vs Conventional)

You’ve probably already heard that regular oil changes are extremely important for the health of your vehicle’s engine. That’s sound advice.  But what you might not know is when it comes to motor oil, the real thing may not be the best thing for your engine.

There are different types of motor oil:

• Conventional oil, extracted from the ground and refined.
• Synthetic oil, manufactured from high-quality base oils and artificially-made chemical compounds.
• Synthetic oil blend, a mixture of conventional and synthetic oils.

The first thing you need to know is that most new engines require synthetic oil.  If synthetic oil is recommended for your car – you MUST use it.

For the rest, there are many advantages to using synthetic oil over conventional oil.

• Synthetic oil provides better protection for your engine while helping it to perform better.
• Conventional oil breaks down over time, while synthetic oil lasts longer.
• Synthetics can stand higher temperature extremes, both heat, and cold.

Synthetic oil can be a better choice if you live in an extremely hot or cold climate or put a lot of strain on your engine by towing or carrying heavy loads.  It also may be good for older engines that sometimes have a tendency to develop sludge.

Synthetic oil is a more expensive option, but you likely won’t have to have your oil changed as often.  Some synthetics are recommended to last 10,000-15,000 miles/16,000-24,000 km between changes.

You might also consider a synthetic blend that gives you some of the advantages of synthetic oil at a lower cost. Have a talk with your service adviser about recommendations for what will best suit your vehicle and driving habits.

It’s interesting to note that in recent years, more than one out of two vehicle owners are opting for synthetic oil or a synthetic blend when they get their oil changed. Sounds like they’re on to something. In the long run, if you have fewer oil changes with synthetics, you’ll use less oil, a bonus for our environment.

Breathe New Life into Your Engine (MAF sensor replacement)

If you’ve noticed your vehicle is hard to start, stalling, or has lost power, the culprit may be a part with an odd name: the MAF sensor.  You may have never even heard of a MAF sensor, but it’s important that it be working correctly, or you may be experiencing some fairly significant engine issues.

All vehicles bring in air and direct it through an air filter before it goes into your engine, where it mixes with fuel to provide power to get you going. There’s a tube-like device with a sensor inside it that measures how much of that mass of air is passing through. That’s why it’s called a mass air flow sensor, or MAF sensor.  If the MAF sensor isn’t working right, the engine’s computer can’t figure out the right amount of fuel to mix with it, and your engine may hesitate or stall.  Sometimes this will cause your Check Engine Light to come on, and any time it does that, make sure you have your vehicle checked by a professional, so you’ll know what’s going on.

When you take your vehicle into your service facility, a technician will thoroughly check the system to see just where the problems are.  If your air filter is dirty, your MAF sensor may get dirty too, which might be causing the problems.  You may find your fuel economy isn’t what it used to be either.

There are other things that can cause the same symptoms, too, such as a leak in a vacuum hose. It’s also possible that the electrical connector between the MAF sensor and the engine has broken. 

The technician can use electronic diagnostic equipment to help pinpoint the exact problem or problems, replace worn parts, and test drive your vehicle to make sure it’s working correctly.

It’s also a good idea to make sure your air filter is changed regularly. A dirty air filter can contribute to a MAF sensor failure. One of the big benefits of having your vehicle regularly maintained at one facility, is they know your vehicle. So, they keep track of which of your vehicle’s parts should be periodically replaced before problems develop. 

If you keep clean air heading into your engine, it can help your engine work efficiently, and with the power it was engineered to deliver. Isn’t that a breath of fresh air?

Serpentine Belt Service at American Brake Centers Inc. in Louisville

Don't you hate it when you hear that squeal from under the hood when you're zipping down a busy Louisville road? It usually means there is a problem with the serpentine belt. The serpentine belt powers a lot of engine accessories. It runs the alternator - which charges the battery; the water pump - which cools the engine; the air conditioning and the power steering pump. All are pretty important parts. It is called a serpentine belt because it snakes around a bunch of engine components.

Serpentine belts are amazingly tough. They can last for years and go long distances. Like all moving parts, however, they eventually wear out. If your belt breaks while you are driving around Louisville, everything will come to a halt within minutes. You need to stop the vehicle immediately or it will overheat, potentially causing engine damage. You can be sure that it won't happen at a convenient time or place. (As if there was a convenient time or place!) You might even need to get your vehicle towed to American Brake Centers Inc.. It's no wonder that vehicle manufacturer's recommend a belt replacement on schedule. It's one of those "have-to's."

Louisville drivers who hear a squeal when accelerating, or a slow, slapping sound at idle, should have their serpentine belt looked at. The pros at American Brake Centers Inc. in Louisville will visually inspect your belt to see if it needs to be changed sooner than scheduled. If the belt has more than three or four cracks every inch or couple of centimeters, has deep cracks that penetrate half the depth of the belt, is frayed, is missing pieces or has a shiny, glazed look, it needs to be replaced regardless of age or mileage.

Serpentine belt replacement is relatively inexpensive, especially compared with the cost and inconvenience of being stranded or getting a disabled vehicle back to American Brake Centers Inc. for repairs.

You're mom was right: an ounce of prevention really is worth a pound of cure.
