Signs of a Bad Rear Differential
- Noise in Gear from an Idle. When the vehicle is turned on and first put into drive, there may be a rattle or clanking noise coming from the rear of the vehicle.
- Grinding Gears at Speed. When the vehicle accelerates, there may be more noises like a hum or continued clank from the rear.
- Vibration and Fluid Leak.
How much does it cost to replace a rear 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.
How many differentials does a car have?
Can a car have two differentials? In case of all wheel drive cars, there are two differentials, one at the back and one for the front wheels. A transfer case is used to split power between front and rear wheels.
What is differential system?
The differential is a device that splits power between 2 wheels. As a car drives straight, its wheels will travel the same distance and rotate at the same speed. An open differential lets either wheel spin at any speed traction allows. The majority of cars on the road have this kind of differential.
