G. Differential Carrier Removal And Disassembly
1. Drain lubricant from differential, remove housing cover and remove axle shafts.2. Remove carrier-to-housing studs, dowel, and locknuts, and gear case-to-brace bolts-to-gear case bolts and disassemble gear case from carrier assembly.3. Loosen ring gear thrust pad lock nut and remove thrust pad.4. Remove differential adjusting nut locks and bearing cap bolts and lockwashers. Remove bearing caps and adjusting nuts by tapping on caps until free from dowels.5. Remove differential and right gear assembly from carrier housing. Exercise care that differential side bearings are not dropped.6. Check differential case to make sure the two halves are marked so they will be reassembled in same relation.7. Remove bolts holding case and cover together.8. Separate cover from case and remove differential side gears, pinion gears, and differential spider.9. Wash all parts in cleaning solvent.10. Inspect ring gear for chipped or worn teeth.11. Check radial clearance between differential side gears and differential case; also fit of differential pinions on spider.12. Inspect spider arms for wear and distortion.13. Inspect splines and teeth of differential side gears and pinions for chipping or excessive wear.14. Inspect differential side bearings and cups for broken races, discoloration, or roughness.15. Remove ring gear from case by tapping back of gear with a soft hammer.16. Inspect ring gear pilot case flange and back of ring gear for dirt or burrs.17. If ring gear is to be replaced, install two guide pins to new gear diametrically opposite each other.18. Start guide pins through case flange and tap ring gear onto case. H. Differential Assembly
1. Lubricate differential side gears and pinions.2. Place differential pinions on spider.3. Assemble side gears and pinions to left half of differential case.4. Assemble right half of differential case to left half, being sure to line up marks on the two halves.5. Install 10 differential-to-ring gear bolts and lockwashers and tighten evenly until ring gear is flush with case flange.6. Remove two guide pins and install remaining two bolts. Tighten all bolts to 85-95 ft. lbs.I. Pinion Disassembly
1. Remove gear case output shaft from pinion. Remove carrier adapter from carrier. Remove output sleeve from pinion.2. Remove pinion and bearing assembly from carrier.3. Drive oil seal from carrier adapter. Discard seal as new part should be used at assembly.5. Press off front double-row bearing assembly.6. Wash all parts in cleaning solvent.7. Inspect pinion for cracked, chipped, or worn teeth. Inspect splines for excessive wear.8. Inspect bearings for excessive wear or discoloration.J. Pinion Assembly
1. Install double row front pinion bearing assembly onto pinion shaft, using a piece of 2-inch pipe to press against inner row, until the collar on inner race seats against the pinion head.2. Press rear pinion bearing on the pinion shaft until chamfered side of inner race seats against shoulder on pinion shaft.3. Install rear pinion bearing and lock ring. Lubricate pinion bearings with engine oil.4. Install pinion and bearings in carrier, Using new gasket, install carrier adapter on carrier, install mounting bolts and lockwashers and torque to 160-170 ft.
