With front-wheel drive being so common in Fort Wayne these days, the differential is just taken care of during a transmission service, so most Fort Wayne folks don’t even have to think about it. And most rear-wheel drive automobile 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 IN 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 automobile 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 North Wells Service Center technicians recommend intervals for replacing your differential fluid.
Your North Wells Service Center 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.
Fort Wayne four wheel drive automobiles 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 North Wells Service Center at different intervals.
Your Fort Wayne service advisor can look up the manufacturer’s recommended service interval or you can check your automobile owner’s manual.
