rearward from axle. Remove cap screws (1), caps (2)
and gaskets (3). Remove nut and lockwasher from
lock pin
(15).
Drive lock pin forward out of axle main
member Using a hammer and punch, drive kingpin
(12) out of axle and spindle. Remove spindle, thrust
bearing (14) and shim (13) if so equipped.
Inspect kingpin bushings (4) and renew if neces-
sary. Bushings should be installed until inner ends
of bushings are 0.016-0.031 inch (0.4-0.8 mm) below
the inside surfaces of spindle bores. Lubrication
grooves in bushings must align with lubrication
fittings.
Install a new thrust bearing (14), with TOP mark
up,
on bottom inside edge of spindle. Install spindle
over end of axle main member with thrust bearing
under axle. Use a jack to hold spindle and bearing
tight against bottom of axle. Using a feeler gage,
measure gap between upper edge of axle and the
spindle. If gap is more than 0.005 inch (0.127 mm),
install shims to reduce gap to less than 0.005 inch
(0.127 mm). Shims are available in thicknesses of
0.005 and 0.010 inch (0.127 and 0.254 mm).
Inspect kingpin (12) and renew as necessary. Install
kingpin with flat nearest to the top and in alignment
with hole for the lock pin
(15).
Install lock pin, lock-
washer and nut. Tighten nut securely. Install steer-
ing arm and tighten bolts (22) and nuts to a torque
of 160-180 ft.-lbs. (217-244 N-m). Install lubrication
fitting in steering arm.
Check oil seal (1—Fig. 2) and install new seal, if
needed, then install hub and adjust bearings as out-
lined in paragraph 1.

ing arm pivot bushings (17) and renew as necessary.
Reinstall by reversing removal procedure, keeping
the following points in mind: Tighten cap screws (16)
and (22) to a torque of 80-90 ft.-lbs. (110-124 N-m).
Bend corners of lock plate (21) against flat of bolt
head (22). Tighten nuts on shoulder bolts (12) to a
torque of 246-272 ft.-lbs. (334-369 N-m). Tighten tie
rod end slotted nuts to a torque of 50 ft.-lbs. (68 N-m).
