Viva la Differential At All Night Auto Repair In Livonia
June 3, 2015
There are a lot of Livonia people who are due for a differential service, but had never heard of a differential before. With front-wheel drive being so common in Michigan these days, the differential is just taken care of during a transmission service, so most Livonia folks 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. So it’s not uncommon for Livonia 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 track at any Michigan high school. 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 SUV wheel and the outside wheel in a turn, because they have to travel together through slightly different distances.
It’s a very important function. When you think of it, all the power to get a SUV moving goes through the differential. Most cars 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 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 recommend intervals for when to replace your differential fluid.
Your friendly All Night Auto Repair 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.
Your All Night Auto Repair service advisor can look up the SUV manufacturer’s recommended service interval or you can check your owner’s manual.
