2. Remove wheel assembly.

3. Remove shock absorber stud nut and palnut (30), retainer, 

and rubber bushing, Figure 5.

4. Remove bolts from upper support arm pivot bracket to 

frame (29), Figure 5.

5. Remove lock screw from eccentric bushing.

6. Remove cotter key and nut from eccentric bushing pivot 

bolt (25).

7. Remove eccentric bushing and steering spindle support 

pivot.

8. Remove upper support arm and pivot assembly.

NOTE: To install, reverse procedure of removal, check 
caster and camber after installation.

UPPER STEERING SPINDLE

SUPPORT PIVOT AND BUSHING

REMOVAL:

1. Jack up car so that wheels clear the floor.

2. Remove upper support arm pivot bolt. 3. Remove upper 

support arm pivot and bushing.

FIGURE 8

4. Screw bushing out of upper support arm and off the pivot 

arm.

INSTALLATION:

NOTE: The upper support arm pivot is self threading. 
The assembling of the upper support arm pivot and bush-
ing requires special tool J -1860, Figure 8, to maintain a 
proper spread of the pressed steel support arm to insure 
proper tension on the threads of the pivot after the bush-
ings have been installed.

1. Install the gauge tool J-1360, Figure 9, on the outer stud 

of the pivot.

FIGURE 9

Install the pivot so that it is central with the tool. Install 
the spreader tool I-1860 so that the two ends of the tool 

rest against the inner faces of the upper support arms 

and the flange of the support arms fits in the slots ma-
chined in the ends of the spreader tool. Turn the hexa-

gon portion of the spreader tool until the gauge rests 
against outer surface of the arms. This will spread the 

arms 1/16".

2. Just start the bushings on both ends of the pivot. Lubricate item 

with a tapping compound such as lard oil which will allow the 

bushings to cut their own threads in the support arm without 
scoring. Install the upper support arm pivot centering gauge J - 

1860 - 2. Thread the bushings into the support arm until the 

head seats tighten to 110 foot pounds. Remove both tools.

NOTE: The upper support arm assembly must have free 
movement so that it is free to drop of it’s own weight, 

plus
