(14) Add the dial indicator reading to the starting
point shim thicknesses to determine the total shim
thickness necessary to achieve zero differential end play.
(15) Add 0.008 in. (0.2 mm) to the zero end play
total. This new total represents the thickness of
shims necessary to compress, or preload the new
bearings when the differential is installed.
(16) Rotate dial indicator out of the way on guide
stud.
(17) Remove differential case, dummy bearings,
and starting point shims from the axle housing.
(18) Install the pinion in the axle housing. Install
the companion flange and establish the correct pinion
rotating torque.
(19) Install differential case and dummy bearings
in axle housing with a single Dummy Shim 8107 on
the ring gear side of the axle and tighten retaining
cap bolts.
(20) Position the dial indicator plunger on a flat
surface between the ring gear bolt heads (Fig. 46).
(21) Push and hold differential case toward pinion.
(22) Zero dial indicator face to pointer.
(23) Push and hold differential case to ring gear
side of the axle housing.
(24) Record dial indicator reading.
(25) Subtract 0.002 in. (0.05 mm) from the dial
indicator reading to compensate for backlash between
ring and pinion gears. Add the resulting measure-
ment to the thickness of the single starting point
shim. This total is the thickness of 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.
