Fig. 17 Rear Differential Disassembly:
Disassemble differential assembly in numbered sequence shown in Figs. 17, noting the following:
1. Proceed as follows:
Fig. 19 Differential Case Replacement:
a. Slowly and carefully pry out differential case assembly using hammer handles, Fig. 19. When removing differential case assembly, ensure side bearing outer race is not dropped. Keep right and left side bearing separate.
Fig. 20 Side Bearing Inner Reace Removal:
b. Pull out side bearing inner races by 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.
c. Scribe alignment marks on differential case and drive gear. Loosen drive gear bolts in diagonal sequence to remove drive gear.
d. Drive out lockpin with a punch and remove pinion gears and washers, side gears and spacers.
e. Using end yoke holder tool No. MB990850, or equivalent, remove companion flange self-locking nut.
f. 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.
g. 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.
h. Drive out drive pinion front and rear bearing from gear carrier.
