Traction-Lok Differential Parts

Inspect the differential clutch packs (4947) for uneven or extreme wear. The dog-eared clutch plates must be free from burrs, nicks or scratches which could cause excessive or erratic wear to the internally splined clutch plates. The internally splined clutch plates should be inspected for condition of the material, and wear. Replace the plates if their thickness is less than 1.5mm (0.058 inch) or if the material is scored or badly worn. Inspect the plate internal teeth for wear. Replace them if excessive wear is evident.

Plates should be replaced as a set only. Examine all thrust surfaces and hubs for wear. Abnormal wear on these surfaces can contribute to a noisy axle on cone-type, traction-lok differential.
