housing .020" to permit installation of differential.
(Do Not spread more than this amount.)
31. Install differential assembly and bearings in housing.
To insure proper seating of bearings in housing, tap
drive gear with a rawhide or plastic hammer.
32. Install bearing caps, coating bolt threads with sealing
compound. Bearing cap marks must match those on
each side of housing, Figure 52. Remove housing
spreader and torque bearing cap bolts to 70 to 90 foot
pounds.
33. Install dial indicator on housing with butt on contact-
ing edge of drive gear tooth and check backlash
between gear and pinion, turning gear and measuring
in four places equally spaced around gear, Figure 52.

should not vary more than .002" between positions
checked.

AXLE SHAFT ASSEMBLY
1. Install axle shafts using care when inserting them in
housing, not to damage new inner oil seals. Lubricate
wheel bearings and start outer cups in housing by
tapping with plastic or rawhide hammer. Use flange

into place.
2. Place housing flange bolts in position and install shim
pack (right side only) removed during disassembly,
between brake backing plates and flanges.

washers and nuts. Install new oil seals in caps and
tighten flange bolt nuts to 12-17 foot pounds.
4. Check axle shaft end play which should range between
.001" and .004". Change thickness of shim pack on
right side if necessary to obtain correct end play.
Shims are available in thicknesses of .003", .005",
