All Wheel Drive

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.
b. Position the remaining hoist arms at each corner of the vehicle in the normal fashion.
c. Raise the vehicle to a comfortable working level.
2. Position an under-hoist utility jack or transmission jack under rear axle toward the side needing spring replacement. Jack pad should just contact axle.

NOTE: If shock absorber bolt deflects upward during 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.
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.
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.





8. Loosen and remove the 2 bolts and the 2 pin nuts from the spring shackle for the rear leaf spring. Then remove the inner half of the spring shackle from the outer half hanger of the spring hanger and the spring.
9. Remove the rear leaf spring from the outer half of the spring shackle.
10. Remove the leaf spring from the vehicle.





11. Loosen and remove the pivot bolt from the front mount of the rear leaf spring.

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. Tighten the 4 mounting bolts to a torque of 61 Nm (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.
4. Raise axle assembly into correct position with axle centered under spring locator post.
5. Install axle plate bolts. Tighten bolts to 95 Nm (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.

CAUTION: The following sequence must be followed 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. Then tighten the retaining bolts for the inner to outer half of the spring hanger to the torque specification listed. 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 Nm (115 ft. lbs.) torque.
9. Tighten rear spring shackle pin nuts to 61 Nm (45 ft. lbs.) torque.
10. Tighten rear spring shackle inner to outer half retaining bolts to 61 Nm (45 ft. lbs.) torque.
11. Tighten the lower shock absorber mounting bolt to 102 Nm (75 ft. lbs.) torque.
