(1) Remove side bearings from differential case.
(2) Install ring gear, if necessary, on differential
case and tighten bolts to specification.
(3) Install Dummy Bearings D-348 on differential
case.
(4) Install differential case in the housing.
(5) Insert Dummy Shims 8107 ( 3.0 mm / 0.118 in.)
starting point shims between the dummy bearing
and the housing (Fig. 8).

(6) Install bearing caps in their correct positions
and snug the bolts.
(7) Using a dead-blow hammer to seat the differ-
ential dummy bearings to each side of the housing
(Fig. 9) and (Fig. 10).
(8) Thread Pilot Stud C-3288-B into rear cover bolt
hole below ring gear (Fig. 11).
(9) Attach Dial Indicator C-3339 to the pilot stud
and position indicator plunger on a flat surface of the
ring gear bolt head (Fig. 11).
(10) Push differential case to the pinion gear side
of the housing (Fig. 12) and zero dial indicator.
(11) Push differential case to the ring gear side
and record dial indicator reading (Fig. 13).
(12) Add the dial indicator reading to the starting
point shim thickness to determine total shim thick-
ness to achieve zero differential end play.
(13) Add 0.008 in. (0.2 mm) to the zero end play
total. This new total represents the thickness of
shims to compress or preload the new bearings when
the differential is installed.

(14) Rotate dial indicator out of the way.
(15) Remove differential case, dummy bearings
and starting point shims from the housing.
(16) Install pinion gear in the housing. Install the
yoke and establish the correct pinion rotating torque.
(17) Install differential case and dummy bearings
in the housing (without shims) and tighten retaining
cap bolts.
(18) Position the dial indicator plunger on a flat
surface between the ring gear bolt heads (Fig. 11).
(19) Push and hold differential case toward pinion
gear.
(20) Zero dial indicator face to pointer.
(21) Push and hold differential case to ring gear
side of the housing and record dial indicator reading.
