When your vehicle makes a turn, the outer wheel has to turn faster than the inner wheel, due to the difference in the length of the paths they take. The differential is the mechanical component that spins the left and right wheels, but lets them rotate at different speeds so your vehicle can turn. It’s located between the two front wheels and attached to each wheel by the axle. (4WDs have a separate differential for each pair of wheels, connected through a transfer case).
Differential fluid provides lubrication to the gears, bearings, shafts, and other internal components. Heat, pressure, and friction can slowly breakdown the additives in the differential fluid. Small particles of metal and clutch material may also come off as they wear. These particles can sometimes mix with the fluid, which in turn becomes contaminated.
When you bring your car in to Automatic Transmissions R Us for a Differential Service, we will:
- Evacuate the old differential fluid
- Fill the differential with manufacturer recommended type and quantity of new fluid
