30. Turn screw on housing spreader J-5231 and with dial<br />
indicator mounted as shown in Figure 40, spread<br />
housing .020" to permit installation of differential.<br />
(Do Not spread more than this amount.)<br />
31. Install differential assembly and bearings in housing.<br />
To insure proper seating of bearings in housing, tap<br />
drive gear with a rawhide or plastic hammer.<br />
32. Install bearing caps, coating bolt threads with sealing<br />
compound. Bearing cap marks must match those on<br />
each side of housing, Figure 52. Remove housing<br />
spreader and torque bearing cap bolts to 70 to 90 foot<br />
pounds.<br />
33. Install dial indicator on housing with butt on contacting<br />
edge of drive gear tooth and check backlash<br />
between gear and pinion, turning gear and measuring<br />
in four places equally spaced around gear, Figure 52.<br />
Backlash should range between .003" and .006" and<br />
should not vary more than .002" between positions<br />
checked.<br />
34. Install housing cover using new gasket and placing<br />
identification tag under one of the screw heads.<br />
AXLE SHAFT ASSEMBLY<br />
1. Install axle shafts using care when inserting them in<br />
housing, not to damage new inner oil seals. Lubricate<br />
wheel bearings and start outer cups in housing by<br />
tapping with plastic or rawhide hammer. Use flange<br />
bolts and brake backing plates to draw bearing cups<br />
into place.<br />
2. Place housing flange bolts in position and install shim<br />
pack (right side only) removed during disassembly,<br />
between brake backing plates and flanges.<br />
3. Install wheel bearing oil seal cap gaskets, caps, lock<br />
washers and nuts. Install new oil seals in caps and<br />
tighten flange bolt nuts to 12-17 foot pounds.<br />
4. Check axle shaft end play which should range between<br />
.001" and .004". Change thickness of shim pack on<br />
right side if necessary to obtain correct end play.<br />
Shims are available in thicknesses of .003", .005",<br />
.010" and .030".<br />
INSTALLATION OF AXLE<br />
1. Place axle assembly in position on rear springs, with<br />
rubber cushions and retainers under spring seats. Engage<br />
heads of<br />
FIGURE 52<br />
heads of spring center bolts in holes in center of axle spring<br />
seats. If the rubber cushions have deteriorated, install new<br />
ones.<br />
2. Replace rear axle "U" bolts, lower spring plates, nuts and<br />
lock nuts. Tighten nuts to a torque of 70-80 foot pounds.<br />
3. Place roller jack under axle housing, elevate slightly and<br />
connect rear shock absorbers at lower end.<br />
4. Connect rear stabilizer to axle housing bracket.<br />
5. Place rear universal joint needle bearing cups in position in<br />
companion flange, install clamps, washers and nuts and<br />
tighten nuts to 14-17 foot pounds torque.<br />
6. Connect brake lines at rear wheel cylinders and brake hose<br />
at frame connection. Bleed brakes.<br />
7. Connect rear ends of parking brake cables to brake operating<br />
levers, position conduits and replace conduit caps.<br />
8. Place brake drum and hub assemblies on axle shafts, install<br />
washers and axle shaft nuts, tightening to 125 to 200 foot<br />
pounds. Install and spread cotter pins.<br />
9. Replace wheels, tighten hub bolts and install hub caps.<br />
10. Remove housing cover filler plug and fill housing to level<br />
of plug opening (3 lbs.) with S.A.E. 90 Hypoid or Multi-<br />
Purpose Gear Lubricant. Replace plug and tighten filler<br />
and drain plugs.<br />
