Fig. 45 Ring Gear Backlash Measurement
The measurement above shows shim thick­
ness necessary to eliminate ring gear backlash.
The shims must be placed at the ring gear
flange side between the case and bearing. Sub­
tract this thickness from case zero end-play
shim thickness. This amount pirns 0.38mm (0.015
in.) will be required for differential bearing

Fig. 46 Differential Housing Separation
(13) Install a pilot stud at the left side of the dif­
ferential housing. Attach Dial Indicator to housing
pilot stud. Load the indicator plunger against the op­
posite side of the housing (Fig. 46) and zero the indi­
cator.
CAUTION: Do not spread over 0.38 mm (0.015 in), if
the housing is over-separated, it could be distorted
or damaged.
(14) Separate the housing enough to install the
case in the housing. Separate housing a maxi­
mum distance of 0.38 mm (0.015 in) with the
spreader tool. Measure the distance with the dial
indicator.
(15) Remove the dial indicator.
preload and backlash. These shim must be
placed on the opposite side.
(5) Remove indicator and pilot stud.
(6) Remove the differential case from housing.
(7) Remove the master bearing tools from the dif­
ferential case hubs.
(8) Position the backlash shims (with determined
thickness) on case hub (ring gear side). Install bear­
ing on the hub with Installer C-4190 and Handle
C-4171.
(9) Position the remaining zero end-play shims on
hub at opposite side of case. Include an additional
0.015-in (0.38-mm) thick shim on this hub. This will
provide the required differential bearing preload
torque.
(10) Install bearing on the hub with Installer
C-4190 and Handle C-4171.
(11) Match each bearing cup with bearing (origi­
nal). Install the cups on the bearings.
(12) Position Spreader W-129B with the tool dowel
pins seated in the locating holes (Fig. 46). Install the
holddown clamps and tighten the tool turnbuckle fin­
ger-tight.
