What is the Rear Differential and How Does It Work?
The Rear Differential is an integral component of the vehicle's driveline. Positioned in the between rear wheels connected to axle shafts, it coordinates with neighboring assemblies to ensure reliable vehicle performance, safety, and fuel efficiency.
Allows outer drive wheels to rotate faster than inner wheels during cornering while splitting engine torque evenly between both sides. In the event of wear or mechanical breakdown, timely diagnosis prevents ancillary damage to interconnected systems like Driveshaft / Propeller Shaft, Transmission / Gearbox.
Common Symptoms of a Failing Rear Differential
High-pitched gear whine during deceleration or acceleration
Fluid dripping from pinion seal
Clunking around tight turns
