III. AXLE ADJUSTMENT

A. General

C. Kingpin Adjustment

Adjustments may be necessary after an accident, in

response to and to correct steering problems, tire

wear problems or as a part of the reassembly process

after a thorough inspection.

B. Wheel Bearing Adjustment

Raise the front of the vehicle with a jack and

secure vehicle with jackstands of suitable

capacity.

Remove front wheels from vehicle.

Remove the brake drum. (Disc style wheels only.)

With the end turned to full steering lock, remove

the bolt and washer retaining the outer drive yoke.

(See fig. 14, Page 9.)

Remove the two cap screws that hold the hub cap

on, then proceed to remove the nuts from the

outer axle shaft drive studs.

The flange should be loose enough to remove by

hand. If not, use suitable bolts in the extractor

holes to remove the outer axle shaft. (See fig. 15,

Page 9.)

Note: If oil is used for wheel bearing lubrication, care

should be exercised to protect brake linings, etc.

Remove the wheel bearing lock nut (See fig. 4,

Page 4) and lockwasher from spindle. Loosen

wheel bearing adjustment nut.

8. Tighten wheel bearing adjusting nut while turning

the hub, back off ½ turn and then tighten to 50

ft. Ibs. torque. (See fig. 4, Page 4.) Back off ¼ turn.

Install the wheel bearing lockwasher with tang in

the spindle keyway and one side or the other

toward the bearing locknut in such a way as to fit

over dowel.

Install the outer locknut and torque to specifi-

cation. With the locknut properly tightened, the

wheel hub should rotate freely.

9. Apply a bead of liquid sealant to outer axle shaft

flange. (See Service Bulletin 738 407, Page 22.)

10.

Reinstall both outer axle shaft nuts and outer drive

yoke washer and bolt. Tighten to specifications.

(Figure 6, Page 4.)

Ressemble the outer axle shaft, being careful

to align the splines on the outer axle shaft with

the outer drive yoke. (Fig. 5, Page 4.)

11. If wheel bearings are oil lubricated, refer to

Section II, A to refill.

12. The kingpins should be readjusted after any

loosening or removal and reassembly of the up-

per or lower kingpin brackets, replacement of

kingpin bushings, etc.

1. The front of the vehicle should be raised and

properly supported. The front wheels should be

taken off the axle.

The lower kingpin jam nut should be loosened and

the lower kingpin ball should be backed down

until it stops.

Loosen the upper kingpin adjusting screw jam

nut. Back off the adjusting screw approximately

four (4) turns.

Place a small bottle jack under the wheel end (See

fig. 6A). Raise the wheel end until the upward

movement stops. By feeling the gap between the

lower kingpin bracket and the suspension yoke

(See fig. 6B), you will be able to determine when

upward movement stops. You have now seated

the upper kingpin.

Fig. 6A

Fig. 6B

Screw the lower kingpin ball stud upward until the

ball makes contact with the bushing. You will feel

a slight resistance in turning the ball stud. (See

fig. 6C.)
