How long will a rear differential last?
A rear differential service consists of removing the rear differential cover, cleaning any old fluid from inside the differential case, resealing the cover, and adding clean fluid. After a rear differential fluid change, most vehicles will go 20,000 to 40,000 miles before it’s due again.
How much does a rear diff replacement cost?
Depending on the make and model of your car, as well as its condition, expect to spend between $1,500 to $4,000. The other factor is if you buy a new rear-diff or a used/rebuilt one. A used or rebuilt one will help you save money, but it won’t have the same warranty as a new one.
How long does it take to replace a rear differential?
There are two bearings in a differential, the one for the pinion, and the one for the side. Once it begins to grind or hum, you’ll have to have one or both of them replaced. Since this requires dismantling the diff, it can take as much as 5-hours to complete, meaning it’s a lot more costly to do so.
Why does my rear differential whine when I turn?

Why do you need a limited slip differential?
A limited-slip diff acts just like an open one, under normal conditions. However, where a limited-slip diff takes things a step further, is that it can limit the amount of power it sends should a wheel lose traction. Meanings it not only provides better stability but increases safety as well.
What happens to the rear end of a rebuilt differential?
Once thorough cleaning is accomplished the differential goes back to our rebuild center to begin assembly. All differentials are fitted with new bearings, carriers, ring and pinion, as well as yokes and seals. After assembly they are painted to lock in the renewed surface we obtained from cleaning.
How does the differential gear ratio work on a car?
