2. Install proper cone over axle shaft splines, seating it
into position in cap half of case.
3. If unit was originally assembled with shims located
between side gears and cones for backlash adjust-
ment, reinstall side gear with shim so that gear may
seat on shim. If unit was originally assembled without
shims, reassemble same way.
4. (2 pinion) Place one spring block in position over gear
face, in alignment with pinion gear shaft grooves.
Install pinion shaft, pinion gears and thrust washers
into cap half of differential case in such a manner that
pinion shaft retaining dowel can be inserted through
pinion gear shaft into differential case. This prevents
pinion shaft from sliding out and causing damage to
carrier (Fig. 4B-12).

(4 pinion) Place one spring block in central position
over gear face. Assemble the four pinions and four
thrust washers onto the pinion cross shaft and place
in position in the cap half of the differential case (Fig.
5. (2 pinion) Insert six springs into spring block that is
already installed into case, then place second spring
block over springs. Note offset construction of spring
block tabs (Fig. 4B-14).
(4 pinion) Insert three springs through center of pin-
ion cross shaft onto spring block that is already in-
stalled into case, then place second spring block on
top of springs (Fig. 4B-15).
6. Install second side gear, face down on spring block so
that side gear will mesh with pinion gears.
