What Is A Differential And Do You Have One?

With front-wheel drive being so common these days in Gig Harbor, Washington, the differential is just taken care of during a transmission service, so most Gig Harbor auto owners don't even have to think about it. And rear-wheel drive differentials don't need to be serviced for years, so it's understandable that it's not something on the top of mind for our Gig Harbor customers. So it's not uncommon for auto owners to not know they have a differential let alone know that it needs service.

Call Mackert Automotive LLC in Gig Harbor at 253-851-3307 for information about differential service, or stop by our Gig Harbor, Washington auto center at 3416-B 57th ST CT NW 98335.

To better understand what a differential does, think about our local Gig Harbor 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 between the inside wheel and the outside wheel in a turn, because they have to travel together through slightly different distances.

It's a very important function for us Gig Harbor car owners. When you think of it, all the power to get a vehicle moving goes through the differential. Most cars in the Gig Harbor, Washington area weigh between three and six thousand pounds - trucks even more. The power from the engine goes through the transmission and then through the differential to the drive wheels.

That's a lot of work and requires very heavy duty parts. And those critical 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 breakdown over time. So auto makers recommend intervals for replacing your differential fluid.

Your friendly and courteous Mackert Automotive LLC service professional will drain the used fluid and check it out for metal bits, which could be a sign of excessive wear on the gears. Then he'll replace the fluid and install the additives if necessary.

Your Mackert Automotive LLC service advisor can look up the automobile manufacturer's recommended service interval or you can check your owner's manual. Give us a call at 253-851-3307 for more information about your differential service.
