Does changing differential fluid make a difference?
In most cases, you will need to change differential fluid every 30,000 to 50,000 miles.

That can lead to differential failure, which is a costly problem.
What kind of fluid goes in rear differential?
Differential fluid, also called gear oil, is the fluid that is poured into the rear differential housing. It needs to lubricate the clutches, gears, and bearings in the rear end. It also keeps all of those components cool so that all of the parts in the differential don’t overheat and belt.

When this occurs it’s best to check the condition of your differential and replace if it’s in a rough condition.
Can rear differential cause transmission problems?
