REMOVAL & INSTALLATION
SPRING BETWEEN AXLE HOUSING AND FRAME
- Place a jack under the rear axle housing. Raise the vehicle and place jackstands under the frame side rails.
- Disconnect the lower studs of the shock absorbers from the mounting brackets on the axle housing.
- Lower the axle housing until the springs are fully seated.
- Remove the springs and insulators from the vehicle.
- Place the insulators in each upper seat and position the springs between the upper and lower seats.
- With the springs in position, raise the axle housing until the lower studs of the rear shock absorbers reach the mounting brackets on the axle housing. Connect the lower studs and install the attaching nuts.
- Remove the jackstands and carefully lower the vehicle.
If one spring must be replaced, the other should be replaced also. If the car is equipped with a rear stabilizer bar, the bar must be removed first.
- Raise and safely support the car at the rear crossmember, while supporting the axle with a jack.
- Lower the axle until the shocks are fully extended.
- Place a jack under the lower arm pivot bolt. Remove the pivot bolt and nut. Carefully and slowly lower the arm until the spring load is relieved.
- Remove the spring and insulators.
- Tape the insulator in place in the frame, and place the lower insulator in place on the arm. Install the internal damper in the spring.
- Position the spring in place and slowly raise the jack under the lower arm. Install the pivot bolt and nut, with the nut facing outwards. Do not tighten the nut yet.
- Raise the axle to curb height, and tighten the lower pivot bolt to 70-100 ft. lbs. (95-135 Nm).
- If removed, install the stabilizer bar and tighten it to 20-27 ft. lbs. (27-37 Nm).
- Remove the crossmember stands, then carefully lower the car.
See Figures 1, 2, 3, 4, 5, 6, 7 and 8
- Raise and safely support vehicle on jackstands.
- Remove rear tire and wheel assembly.
- Remove the rear stabilizer (sway) bar link nuts at both ends of bar. Rotate the bar up and out of the way.
- Disconnect the rear parking brake cable and conduit from the caliper.
- Install three Rotunda Spring Cages 086-00031 or equivalent, to the rear spring, as follows:
- Place a transmission jack or suitable stand under the lower control arm as far outboard as possible.
- Support the rear knuckle by using a wire or other suitable means to support the upper control arm to the frame or body.
- Remove the lower strut/shock mounting bolt, washer and nut.
Control arms must not be lowered until pivot bolts are loose. Do not attempt to remove plastic cap on the front of the pivot nut.
- Mark the toe adjustment cam-to-subframe position with a suitable marker. Loosen both inboard pivot bolts on lower control arm.
- Remove the two bolts and nuts attaching the lower control arm to the knuckle.
- Lower the control arm by carefully lowering the support jack. Make sure the spring cages are properly seated on spring as the control arm is lowered.
- Remove the jack, pull the control arm down fully by hand, then remove the coil spring with the cages in place.
- If necessary, remove the spring center mounting insulators.
If new springs are to be installed, or cages removed from old spring, measure the length of the spring (with cages still installed and spring compressor installed), install a spring compressor D78P-5310-A or equivalent into the spring and compress the spring. Remove the spring cages and then the spring compressor. Install the spring compressor into the new spring and compress to previously measured length, or 10.5 in. (267mm). Install the spring cages and remove the spring compressor.
- Install spring center mounting insulators, if removed.
- Place spring, with cages installed, onto upper and lower control arm seats. The cage with no adjuster must face inward and cages must be closer to the bottom of spring. The spring pigtails can be in any position.
- Position two jackstands under the front bumper reinforcement. This will prevent the vehicle from lifting off of the supporting stands at the rear of the car.
- Position the jack under the lower control arm and raise enough to line up mounting holes, ensuring that the spring seats properly.
- Install the bolts and nuts attaching the control arm to the knuckle and tighten bolts to 110-148 ft. lbs. (149-201 Nm).
- Remove the wire, or other means of support, holding the upper control arm assembly.
- Install the lower strut/shock bolt and nut, tighten nut to 83-113 ft. lbs. (113-153 Nm).
- Remove the jack from under the control arm, and remove the spring cages.
- Connect the parking brake cable to brake caliper assembly.
- Install the stabilizer (sway) bar links and attaching nuts at both ends of bar.
- Set toe adjustment cam to the mark previously made on removal.
- Tighten lower front control arm-to-subframe nut to 166-202 ft. lbs. (225-275 Nm). Tighten the lower rear control arm-to-subframe nut to 142-191 ft. lbs. 192-259 Nm).
- Carefully lower vehicle, then have the alignment checked.
