support. Carefully lower axle until it
can be moved forward out of drive
shaft splines.
Inspect axle pivot bushings for wear'
or damage. Renew bushings if clearance
between differential case trunnions and
bushings exceeds 0.35 mm (0.014 inch).
Use a suitable bushing driver to install
bushings. Be sure that bushings are re-
cessed into axle pivot brackets far
enough to allow for installation of "0"
rings or seals in the pivot brackets.
To reinstall axle assembly, reverse the
removal procedure. Check axle housing
fore and aft end play. Desired end play is
0.30 mm (0.012 inch) or less. If end play
exceeds 0.50 mm (0.020 inch), shims
(4-Fig. 17, 18, 19 or 20) should be in-
stalled in front pivot bracket (1) as re-
quired to obtain desired end play.
