6. Before installing, shims must be measured to in-
sure that the proper thickness is being used. Install
shims of correct thickness to obtain desired clearance
and reassemble and install pinion shaft lock pin. In-
stall thrust washers with concave side towards differ-
ential case.
7. Using Special Tool J-24093, along with a
pound torque wrench, check torque to turn gears
using the following procedure:
a. Install axle shaft into a vise and position differen-
tial case onto axle shaft. See Figure
Figure Raising Side Gear Against Case
Figure Measuring Concave Washer Thickness
EXAMPLE:
1 . Dial indicator reading
2. Subtract concave thrust washer thickness
3. Total ,045.
4. Subtract an additional
5. Shim thickness to be used
5. Turn case over and repeat the above procedure to
check other side gear to differential case clearance.

b. Insert Special Tool J-24093 into opposite side gear,
attach a torque wrench, and check torque to rotate
gear. Figure Permissible torque to turn
gears is 14 to 17 footpounds.
It is necessary to
check
rotating torque of both side
gears.
8. If torque is not correct, it will be necessary to
reshim differential gears. Add first at one side one
shim of the next higher or lower thickness. If this is
not enough, reshim both sides completely.
9. Install ring gear on case making certain their
