How much does it cost to rebuild a differential?
Combined with the few hours of labor required for their replacement, the typical rear differential cost of repair is between $200 and $400. If gears are required, that number jumps a bunch. Rear differential repairs that include a new gear set may be $1,500 or even higher between parts and the labor to replace them.7 Jun 2017
Can you drive on a bad differential?
The severity of the complications if the rear differential goes out while driving with a bad pinion bearing will depend on the problem and the vehicle. In the case of chipped or broken gear teeth, there may a vibration or skip in power. Multiple broken teeth will likely cause thunks and rattling sounds.8 Dec 2019
