2. Grasping the outer circumference of the hub at
the 12 and 6 o'clock positions, push the hub
straight on to the spindle. If difficulty is encoun-
tered, try rocking the hub slightly to free the in-
ner bearing. Once the hub is in position, the
outer bearing and adjusting nut can be installed.
Refer to section 3.2 for wheel bearing adjust-
ment.
3. Install drive flange over the drive studs. Install
the drive flange locknuts and torque to 175 lb-ft.
using a uniformed torque sequence.

5. Grease all lubrication points before returning
the vehicle to service.
7.0 ADDITIONAL SERVICE
PROCEDURES
7.1 STEERABLE DRIVE END REMOVAL
This procedure is useful in cases where it is necessary to
gain access to the inner axle seal or to remove the differ-
ential, yet complete tear down of the steerable end is not
desirable. Removal of the steerable end will be greatly
facilitated if acquisition or fabrication of the special
mounting tool is possible. The steerable end removal
tool is available from Fabco, or it can be fabricated from
the drawings in Section 9.13 Special Tools.
1. Remove the cotter pins from both tie rod ends.
Unscrew both castle nuts so that only a few
threads remain in engagement. Use a suitable
puller to extract the tie rod end from the suspen-
sion yoke. Do not strike the tie rod end ball stud.
Completely remove the nuts and tie rod.
2. Remove all eight 12-point cap screws which se-
cure the universal joint to the axle shaft and
yoke shaft. Pry the joint away from the shafts
and remove. See
Figure 28
.
3. Loosen the upper kingpin adjusting screw jam
nut and back out the adjusting screw until the
spindle yoke stops moving downward and is
resting on the suspension yoke.
4. Remove the steering arm or upper kingpin cap
nuts along with the brake bracket bolts. Using a
7/16 socket, rotate the hex extension on the
front of the slack adjuster counter clockwise. At
the same time the brake bracket will be lifted
back off the steering arm or upper kingpin cap.
5. Remove the steering arm or upper kingpin cap.
If difficulty is encountered, turn the adjusting
screw back in to force the arm or cap off the
studs.
6. Attach the steerable end removal tool to a trans-
mission jack and mount it to the steerable end
by means of the lowest three wheel studs and
nuts. Thread the 3/4"-16 x 5" bolt up through the
bottom of the base plate and into the nut furthest
from the vertical plate. Adjust the bolt to contact
and support the brake drum.
CAUTION: IF THE TOOL IS NOT AVAILABLE,
ALTERNATE MEANS TO SUP-
PORT THE STEERABLE END
MUST BE FOUND BEFORE CON-
TINUING THIS PROCEDURE.
7. Loosen the lower kingpin locknut (see Section
9.14 Special Tools) and completely remove the
locknut, lock washer and lower kingpin ball stud
(see Section 9.15 Special Tools) from the spin-
dle yoke.
8. Remove the 1"-14 upper kingpin bolt. Special
tool number 866 744 (see Section 9.8) should
now be used to pull the upper kingpin ball stud
from the suspension yoke. Using the upper
kingpin ball stud puller, fit one tube over the lo-
cating dowel and the other is allowed to float
freely. Insert the 1 1/8"-12 x 3 1/2" UNF bolt
through the spacer and the tool's central hole.
The bolt should then be threaded into the top of
the upper kingpin ball stud. Tighten the bolt until
the ball stud is pulled free from the suspension
yoke.
9. Roll the jack backward to disengage the steer-
able end from the axle. See
Figure 29 & 30.
