The Need for Speed (Wheel Speed Sensor Maintenance)

Today's vehicles have some pretty amazing technology in them, including a computerized braking system we all pretty much take for granted these days.  Antilock brake systems (ABS) have been around for years but they help drivers stop in much shorter distances reliably than ever before.  When you see your ABS warning light come on, it's important to find out what's causing the problem. It's a safety issue.

Often the problem when the ABS light comes on is a faulty wheel speed sensor.  (In some cases the traction control light will also come on, perhaps because of a non-working wheel speed sensor.) Your vehicle uses the speed sensors to measure the rotational speed at each wheel. That sensor sends the speed data to a computer that can then adjust braking power and prevent your wheels from locking up. 

If any of the wheel speed sensors isn't working right, the ABS warning light will go on and the vehicle's computer will turn off the antilock brake system.  You'll still have working brakes, but you will lose the functionality of that computerized system.

When your vehicle warns you the ABS has a non-working sensor, you can have a technician check to see what's going on. It could be one of the sensors is dirty and a cleaning will solve the problem.  But it also could be that one or more sensors needs to be replaced. 

A technician will use computerized diagnostic equipment to determine what and where the problem is, replace any bad parts and then check to make sure the system is fully operational. 

Antilock brakes and traction control are significant technologies that help prevent your vehicle from slipping on less-than-perfect road surfaces, especially useful during wintery weather.  Make sure they're helping you drive the way they designed to.

Power Steering Service at Long Hill Auto Service in Millington

Many Millington drivers have been hearing about technological advances in power steering, specifically electric power steering. Some very high-end cars have been featuring electric power steering. Power steering fluid has the necessary hydraulic properties and the ability to lubricate the internal parts. The power steering fluid also protects vehicle components from rust and corrosion.

Millington car owners should be aware that vehicle manufacturers recommend that the fluid be replaced on schedule. At Long Hill Auto Service, the old fluid is drained and the system cleaned thoroughly. Fresh fluid is then installed.

Unfortunately, many Millington drivers don't realize how important it is to service their power steering, and some may not even know that it's necessary in the first place. A neglected power steering system can develop leaks that will shorten the life of the pump.

Millington drivers should be aware of warnings that indicate possible power steering problems: the need to constantly add power steering fluid, a loud whining from the pump, erratic power assist or high steering effort. If you're experiencing any of these problems, have your power steering checked out at Long Hill Auto Service in Millington.

In addition to the pump and hydraulic system, there are mechanical parts in the steering system. The rods, arms, joints and knuckles that actually turn the wheels can become worn or damaged. A standard alignment service at Long Hill Auto Service includes an inspection of steering components.

See if you notice any of these: play in the steering wheel, the steering wheel is off center, or there's a noise coming from your front wheels, especially when turning.  If so, have your friendly and knowledgeable Long Hill Auto Service service advisor do an inspection so the problem can be corrected. Waiting too long could cause uneven tire wear and may even lead to steering failure. 

Give us a call.

The Long Hill Auto Service Guide to Servicing Your Differential

Differential? What's that? And what's it for? I've been told by my service advisor that I need to get it serviced, but is that on the level?

Do these questions sound familiar? They're not uncommon for Millington drivers. A lot of us in Millington don't know what a differential is or what it's for. Every vehicle has a differential, and, yes, it does need to be serviced. In fact, it's more important to the operation of your vehicle than the air conditioner or windshield wipers.

A differential allows your vehicle tires to move at different speeds. This happens more than you think. The best example is when a vehicle is turning. The inside wheel travels a much shorter distance than the outside wheel during a turn. This means the outside wheel has to move faster than the inside wheel. Without a differential, your tires would hop and skip while turning. They would also lose traction in sand or snow.

The location of your differential depends on what kind of vehicle you drive. On a rear-wheel drive vehicle, the differential is located in the back. For a front-wheel drive vehicle, it is located on the front, but it is usually called a transaxle. Four-wheel drive vehicles have three differentials: one on the front, one in the back and one in the middle. This center differential compensates for differences in speed between the front and rear wheels.

Your differential contains strong gears that need to be protected from dirt, debris, water and other contaminants. A differential is sometimes referred to as a “gear box.” The work of these gears is to transfer power from the vehicle drive train to the wheels.

Your differential needs fluid to lubricate and cool the gears. This fluid, even though enclosed in the “gear box,” can get dirty because the gears grind down over time, releasing tiny bits of themselves into the fluid. Also, the additives in the differential fluid break down and need to be replaced. That's why preventive maintenance for your vehicle needs to include servicing the differential.

Your owner's manual can give you recommendations on how often to service your differential. But you should also consult with your friendly and knowledgeable Long Hill Auto Service professional. Long Hill Auto Service can give you some good auto advice on whether your vehicle needs to be serviced more frequently. For example, if you drive in hot or cold NJ weather conditions, your differential will need to have its fluid changed more often.

Severe conditions will also affect your vehicle care routine and your differential. Check your owner's manual for a definition of “severe service” conditions that affect your vehicle. Examples may include driving with frequent stops and starts, a lot of short trips around Millington, hot or cold NJ weather conditions and towing.

Off-roading is particularly hard on a vehicle's differential. If you are an off-roader, especially if you cross NJ streams or waterways, it is important that you service your differential more frequently than the recommendations suggest.

Properly servicing your differential will extend its life and keep you out of Millington auto repair shops. A smooth ride is the result of proper preparation and smart choices.

For 4x4s (Maintenance of 4x4 Vehicles)

Some people love 4x4 vehicles, the true 4-wheel drive works of engineering like Jeeps and 4x4 pickups that allow you to seemingly go anywhere on the planet. You can climb up a 40-degree rock trail with some planning and skill (always careful to protect the environment, of course), or you can get through the deepest snow.

But with that added capability comes additional complexity, drive-train components and other systems that less capable vehicles don't have.  And that is why when it comes to 4x4s, you have to maintain them a little differently from those vehicles that spend their lives on pavement.  Here are some of the key things to keep an eye on:

• Transfer case—This transfers power from the engine to the wheels.  A transfer case has fluid in it that needs to be changed at intervals recommended by the manufacturer.  Your service advisor will let you know how often that is and will keep track of your service dates.  You will need to make sure the transfer case seal is working properly.  Otherwise, transmission fluid could get in and cause damage that is costly to fix.  Some transfer cases have an electric motor that shifts it through gears, and its connections are often exposed to the elements, making them vulnerable to damage and corrosion.  Proper maintenance will keep those connections working like they should
• Front and rear differentials—These also have to have the right amount of fluid and should be checked regularly.  Your service advisor can let you know when you need that fluid changed as the owner's manual recommends.  It's important the service is performed correctly with the proper lubricant so it will work the way it is designed to.
• Brake lines—Those 4x4s practically beg to go into wet spots. They also are great machines to conquer snow: road salt, brine and all.  Moisture, salt and brake lines are a recipe for corrosion, so brake lines need to be inspected regularly.  There are anti-corrosion sprays or white lithium grease that can retard corrosion.  Remember, getting there is half the fun, but not being able to stop is no fun at all.

So enjoy your 4x4 and what it can do that other vehicles can't.  Just remember that even though it's tough on the outside, it needs special care to keep it going.  Oh, and remember to take care of the environment when you go off-roading, too.
