With front-wheel drive being so common in Strongsville these days, the differential is just taken care of during a transmission service, so most Strongsville folks don’t even have to think about it. And most rear-wheel drive truck differentials don’t need to be serviced for many miles, so it’s understandable that it’s not something on the top of mind. So it’s not uncommon for Ohio people to not know they have a differential let alone know that it needs service.

To better understand what a differential does, think about a high school track. There are lanes marked off on the track. For the longer distance races, the starting lines are staggered. The starting lines for the outside lanes are ahead of the starting lines for the inside lanes. That’s to compensate for the longer length of the outside lanes. Staggering the starting lines means that each runner has the same distance to run.

The differential compensates for the difference in speeds on drive wheels between the inside wheel and the outside wheel in a turn, because they have to travel together through slightly different distances.

Many truck differentials do a lot of work and require very heavy duty parts. And those parts need protection. The differential fluid lubricates the gears in the differential and keeps them cool. The fluid eventually gets dirty and worn down. Some kinds of differentials require special additives that break down over time. So manufacturers and Strongsville Express Tire technicians recommend intervals for replacing your differential fluid.

Your Strongsville Express Tire service technician will drain the used fluid and check it out for metal bits, which could be a sign of excessive wear on the gears. He’ll then replace the fluid and install the additives if necessary.

Strongsville four wheel drive trucks need special attention to their differentials because they have a differential on both the front and rear axles that work at different times and sometimes under heavy loads – so they may need to be serviced at Strongsville Express Tire at different intervals.

Your Strongsville service advisor can look up the manufacturer’s recommended service interval or you can check your truck owner’s manual.

When you take a corner in your car, 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 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 to keep your differential properly lubricated. Differential fluid cools and protects the gears.

Your Strongsville OH service 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 Strongsville Express Tire (440.238.8473) for 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 lube, oil and filter change as well.

Now, of course differentials eventually wear out and need to be replaced. You might notice a strange noise from you axle area as one of the first warning signs. When the differential shows signs of failing, it’s important to repair it. If you leave it too long and it freezes up when you’re driving you could lose control of your vehicle and other parts like the axle, driveshaft and transmission could be damaged.
