Be careful not to confuse left and right hand parts.
Keep bearing and bearing race for each side together.
2. Loosen ring gear bolts in a criss-cross pattern.
3. Tap ring gear off differential case with a soft hammer.
Tap evenly all around to keep ring gear from binding.
4. Drive out pinion mate shaft lock pin, with punch from ring gear side (2-pinion type differential case).
Lock pin is calked at pin hole mouth on differential case.

Ring Gear and Drive Pinion
Check gear teeth for scoring, cracking or chipping. If any damaged
part is evident, replace ring gear and drive pinion as a set (hypoid
gear set).
Differential Case Assembly
Check mating surfaces of differential case, side gears, pinion mate
gears, pinion mate shaft, thrust block and thrust washers.
Bearing
1. Thoroughly clean bearing.
2. Check bearings for wear, scratches, pitting or ¯aking.
Check tapered roller bearing for smooth rotation. If damaged,
replace outer race and inner cone as a set.
