1. Apply identification punch marks on the carrier, differential bearing cap and adjuster for reassembly purposes, Fig. 1.
2. Remove the adjuster lock plate.
3. Loosen the bearing cap attaching bolts and back off the adjuster slightly with wrench (49 0259 720) to relieve differential bearing preload.
4. Remove the bearing caps and adjusters, Fig. 17.
5. Remove the differential assembly together with the bearing outer races. Make certain that each bearing outer race remains with its respective bearing.
6. If bearing replacement is necessary, remove the bearings from the differential gear case with a suitable puller.
7. Separate the differential case halves by removing the bolts.
8. Remove the side gears, thrust washers, pinion gears and spider.
9. Remove the bolts and washers that attach the ring gear to the gear case. Remove the ring gear.
10. Hold the companion flange with the holder (49 0259 710A) and remove the drive pinion nut.

12. Remove the drive pinion, rear bearing and collapsible spacer from the carrier. If necessary, tap the pinion out with a plastic hammer, while being careful to guide the pinion by hand to avoid damage.
13. Remove the oil seal and front bearing from the carrier.
14. Disassemble and inspect all parts, Fig. 17. If damaged replace as necessary.
