4. Prepare a new inner shaft seal for assembly. Put a
light coat of No. 1 Permatex (or equivalent) on the out-
side diameter (surface that contacts the axle housing),
and a thin film of oil on the inside diameter (surface that
contacts the axle shaft). Install the new seal to a depth
of 1.218 in. (30.90 mm) into the axle housing (Fig. 16).

lock nuts. Tighten the nuts in an alternating pattern so

IMPORTANT: When tightening the lock nuts, hold
the socket head screws with a wrench to prevent the
screw head from damaging the axle tube.

drum with lock nut (item 1).
8. Install wheel assembly on studs and secure with five
(5) lug nuts. Torque lug nuts in a crossing pattern from
75 to 80 ft-lb (102 to 108 N−m).
