- Remove differential case from carrier and remove bearings from differential case in same manner as conventional case. Remove bolts securing ring gear, then remove ring gear by tapping with a soft hammer. Place differential case in a suitable press to load bearing journals so preload of springs is overcome (approximately 1500 lbs.). If a press is not available, two 7/16" bolts and nuts can be used in the ring gear mounting holes (one on each side) to compress case halves and overcome pre-load tension. While under pressure, loosen the two Allen or Phillips head screws which hold case halves together until one or two of the threads remain engaged. Remove case assembly from press. Tap on cover to spring it loose, then remove both screws.
- With cover facing down, lift off case. Remove pre-load spring plate, and springs. From cover remove side gear, four clutch plate ear guides, clutch hub, friction and steel clutch plates and shim(s). With a drift drive out pinion shaft lock pins from case. Drive out long pinion shaft from case, drive from end opposite lock pin hole. Remove two short pinion shafts. Lift out center block, then remove pinion gears, thrust washers and side gear and thrust washer.
