into the spring mount. Install the pivot bolt and nut.
Do not tighten the pivot bolt at this time.

(2) Position the front spring mount for the rear

leaf spring against the floor pan of the vehicle.

mount (Fig. 26). Tighten the 4 mounting bolts to a
torque of 61 N·m (45 ft. lbs.).

(3) Install the rear of the leaf spring onto the outer

half of the rear shackle. Install the inner half of the
rear hanger. Install the pin nuts and bolts on the
rear shackle, but do not tighten at this time.

CAUTION: The following sequence must be fol-
lowed when tightening the pin nuts on the rear
hanger for the rear leaf spring. First the hanger pin
nuts must be tightened to the specified torque
shown below. Then tighten the retaining bolts for
the inner to outer half of the spring hanger to the
torque specification listed below. This sequence
must be followed to properly seat the bushings into
the springs and to avoid bending the spring hanger.

(8) Tighten the spring front pivot bolt to 156 N·m

(115 ft. lbs.) torque.

(9) Tighten rear spring shackle pin nuts to 61 N·m

(45 ft. lbs.) torque.

(10) Tighten rear spring shackle inner to outer

half retaining bolts to 61 N·m (45 ft. lbs.) torque.

(11) Tighten the lower shock absorber mounting

bolt to 102 N·m (75 ft. lbs.) torque.

SPRING - CARGO

REMOVAL

(1) Raise vehicle on frame-contact hoist as follows:

(a) Position the hoist arm supporting the corner

of the vehicle to be serviced against a block of wood
placed on the body sill as shown (Fig. 26).

level.
(2) Position an under-hoist utility jack or transmis-

sion jack under rear axle toward the side needing
spring replacement. Jack pad should just contact
axle.

NOTE: If shock absorber bolt deflects upward dur-
ing removal, raise axle by adjusting support jack. If
shock absorber bolt deflects downward during
removal, lower axle by adjusting support jack (or by
pulling on axle).

(3) Begin removal of the shock absorber lower

mounting bolt (Fig. 27).

(4) Using 2 jack stands positioned under the outer

ends of the axle, raise the axle enough to remove the
weight of the axle from the rear springs.

(5) Loosen and remove the axle plate bolts from

the rear axle (Fig. 28).

(6) Using the jack stands slowly lower the rear

axle, permitting the rear springs to hang free.

(7) Loosen and remove the 4 bolts at the front

mount of the rear leaf spring (Fig. 26).

(8) Loosen and remove the nuts from the spring

hanger for the rear leaf spring (Fig. 35).

(9) Remove the hanger plate from the hanger and

remove the spring from the spring hanger (Fig. 35).

(10) Remove the leaf spring from the vehicle.
(11) Loosen and remove the pivot bolt from the

front mount of the rear leaf spring. (Fig. 30).

INSTALLATION

CAUTION: Pivot bolt must face inboard to prevent
structural damage during installation of spring.

(1) Install the front eyelet of the rear leaf spring

into the spring mount. Install the pivot bolt and nut.
Do not tighten the pivot bolt at this time.

(2) Position the front spring mount for the rear

leaf spring against the floor pan of the vehicle.
Install the 4 mounting bolts for the front spring
mount (Fig. 26). Tighten the 4 mounting bolts to a
torque of 61 N·m (45 ft. lbs.).

(3) Install rear of spring onto rear spring shackle.

Install shackle plate and nuts (Fig. 35). Do not
tighten at this time.

(4) Raise axle assembly into correct position with

axle centered under spring locator post.

(5) Install axle plate bolts (Fig. 28). Tighten bolts

to 95 N·m (70 ft. lbs.) torque.

(6) Install shock absorber bolts. Do not tighten

at this time.

(7) Lower the vehicle and remove hoist arms and

block of wood from under vehicle.

(8) Tighten the spring front pivot bolt to 156 N·m

(115 ft. lbs.) torque.

(9) Tighten rear spring shackle pin nuts to 61 N·m

(45 ft. lbs.) torque.
