Signs of a Bad Rear Differential

42

The rear differential is an integral part of your vehicle that transmits torque and rotation through shafts running the length of the automobile. The rear differential allows all four of the vehicle’s wheels to rotate at different speeds which is essential for road traction and stability. When a rear differential fails, it can cause vibration, noise and fluid leaks that impact a vehicle’s acceleration and driveability. A driver should consult a certified mechanic to deal with a bad rear differential and prevent further damage to the vehicle’s driving systems.

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. This noise may be attributed to the drive shaft universal joints. These joints connect the transmission to the rear differential; and if they have worn down, they could impact the differential by forcing it to work harder, thus wearing down its gears. In order to check the gears of the rear differential, a certified technician will need to be consulted as the procedure requires equipment not commonly available to the consumer.
