SPRINGS, SHOCK ABSORBERS & STABILIZERS 134
2. Insert one end of the spring rear shackle
through the main leaf eye; after insuring the
rubber seals are in place on the shackle start
the threaded bushing on the shackle. DO
NOT TIGHTEN.
3. Install the front end of the spring and spring
front bolt (rubber bushings in place).
4. When proper alignment is obtained, attach
nut and tighten securely.
NOTE: When tightening the mounting bolt, the
rear spring should be mounted so that there is no
unnatural twist set up in the rubber b us hing.
Squeaks at the rear spring front mounting bolts
can be corrected by loosening nuts on rear spring
front bolts and loading car with two or more pas-
sengers before pulling nuts up tight. DO NOT
lubricate the rear spring front bushing.
5. In stall spring pads, mounting clips, nuts and
washers, and tighten nuts to 75 to 80 pounds
torque.
NOTE: It is important that spring clips be in-
spected at regular intervals and kept tight to in-
sure against spring breakage.
6. After mounting clip nuts have been properly
torqued finish tightening the rear shackle nut.
.
NOTE: It is important that the shackle be located
properly to insure the bushing being threaded far
enough on the shackle but not far enough to bot-
tom the thread in the bushing as the shackle
moves in its normal operation. Bottoming will
cause a hard ride and shackle breakage. Spring
shackles should b e inspected periodically to make
sure that they are tight but not binding.
7. Install brake cable retaining clip on top of the
spring.
8. Attach lower end of shock absorbers to
spring mounting clip pads.
9. Lubricate the spring shackles and lower car.
REAR SPRING SHACKLE
IDENTIFICATION
The right hand rear spring shackle has right
hand threads on both upper and lower ends; the
left rear spring shackle has right hand threads
on the upper end 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: 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
.
Use only viscous chassis lubricant at fittings.
Springs without covers are equipped with inserts
and must not be lubricated.
SHOCK ABSORBERS
Direct double acting hydraulic type shock
absorbers are used at the front and rear. The front
shock absorbers are mounted axially within the
front coil springs and are cushioned at the upper
and lower ends in rubber grommets.
The rear units are identical in construction to the
front units and are mounted diagonally for greatest
efficiency and increased stability. At the upper end
they are attached t o the frame crossmember, while
at the lower end they are assembled to the rear
spring clip plates.
Both front and rear shock absorbers are non-
serviceable and are not interchangeable. Defective
units must be replaced.
Shock absorbers are available in either standard
control or heavy control (Optional).
The extra heavy duty control shock absorbers are
available as an additional option.
NOTE: All shock absorbers have the part num-
ber and code stamped on the outside of the shock
absorber.
SHOCK ABSORBER NOISE
When checking for noise, first determine that the
noise is coming from shock absorbers and not
from other sources.
Check the front shock absorber top nut with its
palnut and that rubber bushings are tight and in
good condition, also that the cap screws and nuts
at the bottom of the front shocks are tight.
