Differential Service in Weston/Wausau

Why do I need a Differential Service

When Weston or Wausau drivers take a corner in their vehicle, the outside wheels have a slightly longer distance to go than the inside wheels. That means that the outside wheels have to turn a bit faster than the inside. The piece of mechanical wizardry that makes this possible for is called the differential.

The differential allows the drive wheels to rotate at different speeds in turns without the wheel binding or hopping. If you have a rear-wheel drive vehicle, the differential is on the rear axle. You've seen that bulge in the middle of the axle when you're behind a truck; that's the differential.

 If you have a front-wheel drive vehicle, the differential function is handled by your transaxle. Of course, all-wheel drive vehicles have differentials on both axles. They also have a center differential or a transfer case between the front and rear axles to compensate for speed differences between the front and rear.

Because all the power of the engine is transferred through the various differentials, you can imagine that they are very strong and are built last a long time. That's why it's important for Weston drivers to keep their differential properly lubricated. Differential fluid cools and protects the gears.

Your friendly and knowledgeable Griesbach Auto Service INC. technician will check differential fluid level and top it off if necessary. With low fluid, the differential will run too hot and wear prematurely. Ask your service advisor at Griesbach Auto Service INC. Weston (715.355.1553) or Wausau (715.203.8808) when it's recommended to change your differential fluid. Fresh fluid will extend the life of your differential. Your technician will also inspect the u-joints which connect your drive shaft to the differential and may recommend service. Some u-joints can be lubricated as part of a routine Griesbach Auto Service INC. lube, oil and filter change as well.

Weston and Wausau drivers need to know that differentials eventually wear out and need to be replaced. You might notice a strange noise from your axle area as one of the first warning signs. When the differential shows signs of failing, it's time to repair it. WI residents who leave it too long run the risk of it freezing up when they're driving and could lose control of the vehicle. Plus, other parts like the axle, driveshaft and transmission could be damaged.

Air Bags

Supplemental Restraint System

After they’ve had an accident, some people wonder why their airbags didn't go off. Movies and television lead us to believe that airbags go off with the slightest bump. The reality is much more complicated. First, airbags come out with great force and speed. Now getting hit in the face with an airbag is way better than getting hit in the face with a windshield – but if the accident impact isn't hard enough that you would be severely injured, the airbags may not be triggered at all because they could do more harm than good.

So how does your vehicle know when an accident is likely to result in life threatening injuries that would merit deploying the airbags? Well, there are sensors all around your vehicle that send information to the Supplemental Restraint System (SRS) computer that decides which airbags should be deployed and when. There are impact sensors that measure the direction and intensity of an impact in the front, rear and sides of the vehicle. There are seat sensors that determine if someone is sitting there as well as how much they weigh. This way an airbag doesn't go off when no one is in a particular seat and it can deploy with less force for a smaller person.

The SRS computer takes into account vehicle speed and if there is a rollover. Built into the computer program are the design specifications of your vehicle as they relate to “crumple” zones in a crash. As you can imagine, the computer program is pretty sophisticated.

Now when an airbag does actually go off, there are some things Weston and Wausau residents should know about the repairs necessary to the SRS system. First, the deployed airbag should be replaced. Experts recommend that only a factory certified replacement airbag be used. Airbags are valuable enough that they are frequently stolen or recovered from junked vehicles in the Wausau area. No one can vouch for these airbags, so a certified replacement is essential.

When the driver side airbag in the steering wheel deploys, the steering wheel clock spring is usually damaged and should be replaced. Also, an “airbag worthy” event pre-triggers all of the sensors we've been talking about. In this pre-triggered state, something as slight as hitting a pothole could cause airbags to deploy. So after an airbag has actually been deployed, all of the SRS sensors throughout the vehicle should be replaced. Obviously, airbag work should only be undertaken by qualified service technicians.

Finally, when you start your engine, you will briefly see the SRS dash light come on and then turn off. This is a system self-test. If the SRS light remains illuminated, that means the system has detected a problem that could affect the proper deployment of your airbags. If that happens, get into Griesbach Auto Service INC. as soon as you can to have the fault diagnosed and repaired.
