What Are the Symptoms of a Damaged Differential?
1 Answers
Differential damage manifests as jerking or impact sensations during acceleration or deceleration; below is additional information: Other methods to identify differential damage: Unusual noises from the differential; significant resistance when turning, and in severe cases, the vehicle may fail to start. Structure and function of the differential: The automotive differential is a mechanism that allows the left and right (or front and rear) drive wheels to rotate at different speeds. The differential primarily consists of left and right axle gears, two planetary gears, and a gear carrier. Its function is to enable the left and right wheels to rotate at different speeds when the car is turning or driving on uneven surfaces, ensuring that both drive wheels perform pure rolling. The differential is installed to adjust the speed difference between the left and right wheels. In four-wheel drive vehicles, to drive all four wheels, they must be interconnected. If all four wheels are mechanically linked, the car cannot rotate at the same speed when driving on curves. To allow the car to rotate at nearly the same speed during curve driving, an intermediate differential is added to adjust the speed difference between the front and rear wheels.
