Special Tool:

Inspect the differential case assembly and drive pinion before they are removed from the rear axle housing. These inspections can help find the cause of the concerns and determine the correction needed.
1. Wipe the lubricant from the internal working parts and look at the parts for wear or damage.
2. Check magnetic filler plug for any accumulation of metal particles and clean thoroughly.
3. Rotate the gears to see if there is any roughness which would indicate worn or damaged bearings or gears.
4. Check the ring gear teeth for signs of scoring, abnormal wear, nicks or chips.
5. Set up Dial Indicator with Bracketry 100-002 (TOOL-4201-C) or equivalent and check ring gear backlash and ring gear back face runout.
6. Proper ring gear and pinion clearance assembly must be checked using the Pinion Depth Gauge Set 205-S127 (T79P-4020-A) which shows correct drive pinion bearing adjustment shim (4663) required to ensure acceptable running condition.
