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.
