1. Install side gears without thrust washers or shims.
BARREL
2. Lubricate and install pinion gears and thrust
washers between the side gears 180 degrees apart and
rotate the gears as an assembly until the pinion gear
bores are aligned with the pinion shaft bores in the
case.
3. Install pinion shaft.
4. Install Special Tool J-24093 and, with the use of
a dial indicator, check end play clearance between
side gear and case as follows:
a. Zero dial indicator on end of Tool J-24093. See
Figure
Figure Installing Barrel Sleeve
When the drive pinion end play is eliminated, the
preload specification is being approached. If this
specification is exceeded, replace the collapsible
spacer.
10. Remove installer J-22938 and install washer and
pinion preload nut. Using Special Tool J-22932, hold
barrel

Measure the thickness of the concave thrust
washer by using a to micrometer and subtract
this dimension from the dial indicator reading as
obtained in step b. Record dimension. See Figure

d. After obtaining a dimension by subtracting con-
cave
thrust washer thickness from dial indicator
reading, subtract an additional to obtain the
