shims to compress, or preload the new bearings when
the differential is installed.
(15) Rotate dial indicator out of the way on the
guide stud.
(16) Remove differential case and dummy bearings
from axle housing.
(17) Install the pinion gear in axle housing. Install
the pinion yoke, or flange, and establish the correct
pinion rotating torque.
(18) Install differential case and dummy bearings
D-348 in axle housing (without shims), install bear-
ing caps and tighten bolts snug.
(19) Seat ring gear side dummy bearing (Fig. 70).
(20) Position the dial indicator plunger on a flat
surface between the ring gear bolt heads. (Fig. 71).
(21) Push and hold differential case toward pinion
gear (Fig. 74).
(22) Zero dial indicator face to pointer (Fig. 74).
(23) Push and hold differential case to ring gear
side of the axle housing (Fig. 75).
(24) Record dial indicator reading (Fig. 75).

(25) Subtract 0.002 in. (0.05 mm) from the dial
indicator reading to compensate for backlash between
ring and pinion gears. This total is the thickness
shim required to achieve proper backlash.
(26) Subtract the backlash shim thickness from
the total preload shim thickness. The remainder is
the shim thickness required on the pinion side of the
axle housing.
(27) Rotate dial indicator out of the way on guide
stud.
(28) Remove differential case and dummy bearings
from axle housing.
(29) Install side bearing shims on differential case
hubs.
(30) Install side bearings and cups on differential
case.
(31) Install spreader W-129-B, utilizing some items
from Adapter Set 6987, on axle housing and spread
axle opening enough to receive differential case.
(32) Install differential case in axle housing.
(33) Remove spreader from axle housing.
