Axle Click Noise - Louder on Turns - kw bearing chatter differential gear rattle

When servicing the vehicle with the VIN you entered, the following diagnosis might be helpful if the vehicle exhibits the described symptoms.

Rear axle click noise which is louder during turning manuevers, slalom type manuevers or when exiting or entering sweeping curves.

Camaros and Firebirds equipped with the Zexel Torsen axle can have a clicking noise related to "radial gear float". When the differential is not loaded, the side gear can achieve a neutral bias and float in the planetary gear set. When load is applied either in coast or pull, the side gear fully contacts the planetary gear set eliminating the float. When gear float occurs, a slight clicking noise can be heard. This is a normal condition and no repairs shoulds be attempted to correct the complaint.

Clicking noises when the gear set is loaded, can be an indication of components other than the differential set. Things that may cause a clicking noise: Look at the face of the ring and pinion and side gears for nicks or look at bearing races for signs of scratches or pitting.
