2. Lower the car, which will compress spring and position
lower support arm pivot to frame crossmember.
3. Install lower support arm pivot attaching bolts and
tighten securely.
4. Install shock absorber.
REAR SPRINGS
Rear springs are long leaf, semi-elliptical design. The front
ends are attached to frame brackets with pivot bolts cush-
ioned in rubber. This eliminates noise and allows for in-
creased riding comfort through reduction of torque and
brake reaction shock. (No lubrication is required at this
point).
FIGURE 3
The rear ends of the springs are attached to the body
frame rail s through threaded, self-adjusting "U" type shack-
les operating in hardened steel, threaded bushings. The
bushing threads are protected from road splash and dirt by
rubber sleeve seals retained in position by the shoulders of
the shackles. These seats are installed on the "U" shackle
before inserting the shackles in the bushings.
Rubber cushions and retainers are used between the
spring mounting pad and spring to reduce road noise to a
minimum.
The rear springs of some cars equipped with metal covers.
This type spring should be lubricated every 10,000 miles.
Lubricate through hole in cover using viscous chassis lubri-
cant, use special tool for that purpose.

REAR SPRING
ASSEMBLING :
The leaves should be assembled in their proper order with
a piece of 5/16" rod passing through the center bolt hole of
each leaf. DO NOT lubricate springs equipped with insert.
1. Clamp the loose assembly in a vise and draw the leaves
together, keeping them in alignment as the vise is tightened.
The bracket for holding the brake cable clip is assembled
under the second from front leaf clip.
2. Use two new box type leaf clips, bolts, and spacers.
3. Insert the center bolt and tighten the nut. Use the original
leaf clips that are riveted to the bottom spring leaf at
outer ends.
4. Install the spacers, bolts, and nuts.
