Pinion Gear: Testing and Inspection
After Disassembly
^
Examine the pinion and ring gear teeth for scoring or excessive wear. Worn gears cannot be rebuilt to correct a noisy condition. Gear scoring is the
result of excessive shock loading or the use of an incorrect lubricant. Scored gears cannot be reused.
^
Examine the teeth and thrust surfaces of the differential side gears. Wear on the hub of the differential side gear can cause a chucking noise known
as chuckle when the vehicle is driven at low speeds.
^
Wear of splines, thrust surfaces or thrust washers can contribute to excessive driveline backlash.
