Pre-Disassembly Inspection
NOTE:
It is recommended, but not necessary, that axle housing be removed for overhaul. See Fig 1 to identify differential components throughout overhaul procedure.
- Before disassembly, visually inspect differential parts for wear and/or damage. Rotate gears and check for any roughness which would indicate damaged bearings or gears.
- Check ring gear teeth for scoring, nicks, chips or wear. Measure ring gear runout. Mount dial indicator onto axle housing so tip of dial indicator contacts back of ring gear. Runout should not exceed .004" (.10 mm).
