Disassembly

Disassembly
PRE-INSPECTION





- Before disassembling final drive, perform the following inspection.
- Total preload
a. Turn drive pinion in both directions several times to seat bearing rollers correctly.
b. Check total preload with Tool.
Tool number: ST3127S000 (J25765-A)
Total preload: 1.2 - 2.0 Nm (12 - 20 kg-cm, 10 - 17 inch lbs.)





- Ring gear to drive pinion backlash
Check backlash of ring gear with a dial indicator at several points.
Ring gear-to-drive pinion backlash: 0.13 - 0.18 mm (0.0051 - 0.0071 inch)





- Ring gear runout
Check runout of ring gear with a dial indicator.
Runout limit: 0.08 mm (0.0031 inch)





- Tooth contact
Check tooth contact.
- Side gear to pinion mate gear backlash Measure clearance between side gear thrust washer and differential case with a feeler gauge.
Clearance between side gear thrust washer and differential case: 0.10 - 0.20 mm (0.0039 - 0.0079 inch)

DIFFERENTIAL CARRIER





1. Mount final drive assembly on Tool.
Tool number: ST06340000 (324310, J34310)





2. Put matchmarks on one side of side bearing cap with paint or punch to ensure that it is replaced in proper position during reassembly. Bearing caps are line-bored during manufacture and should be put back in their original places.





3. Remove side lock fingers and side bearing caps.





4. Remove side bearing adjuster with Tool.
Tool number: ST32580000 (J34312)





5. Remove differential case assembly with a pry bar.





Be careful to keep the side bearing outer races together with their respective inner cones-do not mix them up.





6. Remove drive pinion nut with Tool.
Tool number: KV38108300 (J44195)
7. Remove companion flange with puller.





8. Take out drive pinion together with pinion rear bearing inner cone, drive pinion bearing spacer and pinion bearing adjusting shim.





9. Remove front oil seal and pinion front bearing inner cone.
10. Remove pinion bearing outer races with a brass drift.





11. Remove pinion rear bearing inner cone and drive pinion adjusting washer.
Tool number: ST30031000 (J22912-01)

DIFFERENTIAL CASE





1. Remove side bearing inner cones. To prevent damage to bearing, engage puller jaws in groove.
Tool number:
A ST33051001 (J22888-20)
B ST33061000 (J8107-2)





- Be careful not to confuse the left and right hand parts. Keep bearing and bearing race for each side together.





2. Loosen ring gear bolts in a cries-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.
- Lock pin is caulked at pin hole mouth on differential case.
