Disassembly

Fig. 18 Rear Differential Disassembly:

Disassemble differential assembly in numbered sequence shown in Figs. 18, noting the following:

1. Proceed as follows:
a. Using spanner wrench tool No. MB991367 and pin tool No. MB991385, or equivalents, remove side bearing nut.
b. Using a suitable press, push differential case until it is pressed against the carrier.
c. Remove differential case from press. Insert two spacers in diagonally opposite positions between side bearing outer race to be removed and inner race. Using a press, remove outer race. Do not allow side bearing to drop. Keep right and left bearings separate. Use a spacer 1.18 inches long, .39 inch wide and 0.04-0.08 inch high made of copper to prevent damage to bearings.

Fig. 20 Side Bearing Inner Reace Removal:

d. Pull out side bearing inner races using insert tool No. MT303173, pinion carrier bearing puller tool No. MB990339-01 and side bearing cup remover step plate tool No. MB990811-01, or equivalents, Fig. 20.
e. Scribe alignment marks on differential case and drive gear. Loosen drive gear bolts in diagonal sequence to remove drive gear.
f. Using end yoke holder tool No. MB990850, or equivalent, remove companion flange self-locking nut.
g. Scribe alignment marks on drive pinion and companion flange. Remove out drive pinion together with drive pinion spacer and shims. Marks should not be made on contact surfaces of companion flange and shaft.
h. Pull out drive pinion bearing inner races by using insert tool, pinion carrier bearing puller tool, and side bearing cup remover step plate tool, or equivalent.
i. Drive out drive pinion front and rear bearing from gear carrier.
