14 - 4 SPRINGS, SHOCK ABSORBERS, & STABILIZERS
REAR SPRING
INSTALLATION:
1. Place rear spring in position on the rear axle mounting
pad.
2. Insert one end of the rear spring shackle through the main
leaf eye after placing the rubber dust seals in place on the
shackle and start the threaded bushing on shackle. (DO
NOT TIGHTEN).
3. In stall the front end of the spring with rubber bushings in
place and attach spring bolt with the spring bolt rubber
bushing on the bolt.
4. When proper alignment is obtained, attach nut and tighten.
NOTE: When tightening the mounting bolt, the rear spring
should be mounted so that there is no unnatural twist set up in
the rubber bushings. Squeaks at rear spring front mounting
bolts can be corrected by loosening nuts on rear spring front
bolts and loading car with two or more passengers before pull-
ing nuts up tight. No lubrication is required.
5. Install spring pads, mounting clips, nuts, and washers,
and tighten nuts to 55-75 lbs. torque.
NOTE: It is important that spring clips be inspected at
regular intervals and kept tight to insure against spring
breakage. Tighten spring clip nuts to 55-75 lbs. torque.
6. Finish tightening the rear shackle nut.
It is important that the shackle be located properly so as
to insure the bushing being threaded far enough on the
shackle but not far enough to bottom the thread in the
bushing as the shackle moves in its normal operation.
Bottoming will cause a hard ride and shackle breakage.
NOTE: Spring shackles should be inspected periodically
to make sure that they are tight but not binding.
7. Install brake cable retaining clip on top of spring.
8. Attach lower end of shock absorbers to, spring mounting
pads.
9. Lubricate the spring shackles. 10. Lower car and remove
jacks.
FIGURE 4
REAR SPRING SHACKLE
IDENTIFICATION
The right hand rear spring shackle has right hand threads
on both upper and lower ends and the left hand rear spring
shackle has right hand threads on the upper and left hand
threads on the lower end.
The lower left hand shackle bushing is left hand thread
and has an identification groove 1/16" wide on the head.
NOTE: The shackle having the left hand thread has a
single forging mark at the shoulder.
If the zerk fitting is removed and replaced for any reason
it must not be turned into the tapped hole so tightly as to
cause the zerk fitting to bottom on the end of the shackle
and thus loosen the plug that is in the end of the shackle
bushing.
