(7) Remove Tools J-8614-01 and J-22575.
(8) Measure torque required to turn pinion gear us
ing an inch-pound torque wrench and Tool J-22575. Cor
rect pinion bearing preload torque is 17 to 25 inch-
pounds (2 to 3 N«m) torque. Continue tightening pinion
nut until required preload torque is obtained.
CAUTION: Do not exceed the specified preload torque
and do not loosen the nut to reduce preload torque if the
specified torque is exceeded.
(9) If pinion bearing preload torque is exceeded,
remove pinion gear, replace collapsible spacer and pin
ion nut, and adjust preload again.
Differential Case Assembly
(1) Install differential bearings on case using Tools
J-21T84 and J-8092 (fig. 2F-40).
(2) Install thrust washers on differential side gears
and install gears in differential case.
(3) Install differential pinion gears in case. Install
thrust washers behind pinion gears and align pinion
gear bores.
(4) Rotate differential side and pinion gears until
pinion mate shaft bores in pinion gears are aligned with
shaft bores in case.
(5) Install thrust block in case. Insert block through
side gear bore. Align bore in block with pinion mate
shaft bores in pinion gears and case.
(6) Install pinion mate shaft. Align lockpin bore in
shaft with bore in case and install shaft lockpin.

Fig. 2F-40 Differential Bearing Installation
Differential Bearing Adjustment
(1) Place bearing cup over each differential bearing
and install differential case assembly in axle housing.
(2) Install shim on each side between bearing cup
and housing. Use 0.080 inch (2 mm) shims as starting
point (fig. 2F-41).
(3) Install bearing caps and tighten bolts finger-
tight. Mount Dial Indicator J-8001 on housing (fig. 2F-
42).
(4) Using two screwdrivers, pry between shims and
housing. Pry assembly to one side and zero indicator
then pry assembly to opposite side and read indicator.
NOTE: Do not zero or read indicator while prying.
(5) Amount read on indicator is shim thickness that
should be added to arrive at zero preload and zero end
play. Repeat procedure to ensure accuracy and adjust if
necessary.
