The rear suspension consists of the rear axle and
attachments that secure it to the springs and shock
absorbers (Ref Fig. 1 on page L-2). In addition the rear
axle is secured to the rear of the engine by means of a
casting that is bolted to the engine and mounted to the
rear axle with ‘U’ bolts. This section is confined to the
removal and replacement of the springs and shock
absorbers. Rear axle shaft removal is covered in REAR
AXLE section.
Shock Absorber Removal
Raise the rear of the vehicle in accordance with the
instructions provided in Section ‘B’ of this manual and
support the rear of the vehicle on the outer ends of the
rear bumper.
Remove the bottom shock absorber nut (1)
(Ref. Fig. 1).
Compress the shock absorber (2) and remove the top
shock absorber nut (3).
Remove the shock absorber.
Shock Absorber Installation
Shock absorber installation is in the reverse order of
disassembly except that the shock absorber nuts (1,3)
must be tightened until the shock absorber bushings (4)
expand to the diameter of the shock absorber washer
(5).
Rear Spring Removal
To reduce the possibility of personal injury,
follow the lifting procedure in section ‘B’ of this
manual. Place wheel chocks in front and
behind the front wheels and check the stability
of the vehicle on the jack stands before start-
ing any repair procedure. Never work on a
vehicle that is supported by a jack alone.
If both springs are to be replaced and the rear axle is not to
be removed, it is important to remove and replace one spring
at a time. Springs must be replaced in sets. Never replace just
one.
Remove the bottom shock absorber nut (1) (Ref. Fig. 1)
Place a floor jack under the center section of the rear
axle (6) and raise just enough to place a second set of
jack stands under the axle tubes. With both the rear
axle and the frame supported, the ‘U’ bolt (7) and the
hardware (8) can be removed.
Remove the hardware (9) of rear spring shackle
assembly and the front spring mounting hardware (10).
Remove the spring (11).
Rear Spring Installation
Spring installation is in the reverse order of disassem-
bly.
When installing the rear spring shackles, be sure that the
cupped side of the shackle plate faces the spring.
The shock absorber nuts (1,3) must be tightened until
the shock absorber bushings (4) expand to the diame-
ter of the shock absorber washer (5) (Ref. Fig. 1).
Tighten the front spring hardware (10) to 21 - 25 ft. lbs.
(28 - 34 Nm) torque.
Tighten all other hardware to 18 - 22 ft. lbs. (24 - 30
Nm) torque.
