Inspection after Disassembly

Reduction Gear
Check the teeth for wear, pitting, flaking, or chipping.
Minor flaws on the tooth surface can be repaired by grinding with an oil stone or a hand grinder. Check the teeth for contact. If the gear is badly damaged and requires replacement, replace the pinion too. Reduction gear and pinion are a matched set and must be changed at the same time.

Differential
1. Check the differential cases for damage.
Check in particular the seat formed of each case for carrying the side bearing inner race to see whether the seat surface is galled or not.
2. Check the sliding surfaces of the thrust washers and gears for wear or damage.
3. Check the teeth of the differential pinions and bevel gears for wear, pitting, chipping, or galling.
4. Check the fit of each pinion on the spider

Fit of differential
A: 0.02 to 0.07 (0.0008 to 0.0028)
B: 0.35 (0.0138)
