3A-2 FRONT SUSPENSION
INSPECTION PROCEDURE
l. Inflate tires to proper pressure :
Steel belted bias ply tires - 60 psi .
General Jumbo steel belted radial tires
- 65 psi .
2. Check ride height for sag and uneveness .
Before adjusting front ride height, park the
vehicle on a known level surface and adjust the
rear ride height . (Refer to "RIDE HEIGHT" in
Section 4 of this supplement .)
3. Adjust
front
ride
height
(figure 21) .
(Refer to "RIDE HEIGHT" discussed later in
this section .)
If you are unable to adjust the front ride
height to 13-1/8" plus or minus 1/4", it will be
necessary
to
change the torsion bar anchor
arm.
Use the following guide to select the
proper anchor arm :

If changing the anchor arm does
the ride height, inspect the lower control arm
for galling, bulging or splitting, and inspect the
control arm end of the torsion bar for wear .
Replace as necessary .

3 . Check shock absorber control . (Refer to
"Front

4. Check wheels and tires for runout and
wobble .
(Refer
to Sec .
10,
Maintenance
Manual X-7525 .)
5 . Check tires for side wear, misalignment
wear, cornering wear or uneven wear .
(Refer
to Sec . 10, Maintenance Manual X-7525 .)
6. Check brakes for dragging .
(Refer to
"Brake System Trouble Diagnosis," Sec .
5,
Maintenance Manual X-7525 .)
7 . Check front hub bearings for wear or
adjustment. (Refer to "Hub Bearing" later in
this section .)
8 . Check ball joints for looseness .
(Refer
to "Ball Joint Checks" later in this section .)
9. Check
all
steering
connections
for
looseness
or
binding .
(Refer
to
"Front
Suspension
and Steering
Trouble
Diagnosis
Chart" later in this section .)
10. Inspect
the
intermediate
rod
for
paralleism with the front axle to eliminate the
possiblity of front tires wearing unevenly . The
parallelism can be measured and corrected as
follows (see figure A) :
a. Position vehicle on a level surface .
b. Record
the
following
(Refer to figure B)
measurements :
