When Pascagoula 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 Pascagoula drivers to keep their differential properly lubricated. Differential fluid cools and protects the gears.
Your friendly and knowledgeable Clark's Professional Car Care technician will check differential fluidlevel and top it off if necessary. With low fluid, the differential will run too hot and wear prematurely. Ask your service advisor at Clark's Professional Car Care (228.762.3383) 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 Clark's Professional Car Care lube, oil and filter change as well.
Pascagoula 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. MS 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.
