REMOVAL & INSTALLATION
See Figures 1, 2, 3, 4 and 51983-88 Vehicles
- Raise the front of the vehicle and place safety stands under both sides of the jack pads just back of the lower control arms so the lower control arms hang free.
- Remove the wheel and tire assembly.
- Remove the brake caliper and support out of the way with a piece of wire.
- Disconnect the tie rod from the steering spindle, using Tie Rod End Remover Tool-3290-D or equivalent.
- Detach the stabilizer bar link from the lower control arm.
- Unfasten the steering gear bolts, if necessary, and move the steering gear out of the way so that the suspension arm bolt can be removed.
- Use Spring Compressor Tool T82P-5310-A or equivalent, to place the upper plate in position into the spring pocket cavity on the crossmember. The hooks on the plate should be facing the center of the vehicle.
- Install the compression rod into the lower arm spring pocket hole, through the coil spring, into the upper plate.
- Install the lower plate, lower ball nut, thrust washer and bearing, and forcing nut onto the compression rod.
- Tighten the forcing nut on the compressor tool until a drag on the nut is felt.
- Remove the suspension arm-to-crossmember nuts and bolts. The compressor tool forcing nut may have to be tightening or loosened for easy bolt removal.
If a new spring is to be installed, mark the position of the upper and lower plates on the spring with chalk. Measure the compressed length of the spring as well as the amount of the spring curvature to assist in the compressing and installation of a new spring.
- Loosen the compression rod forcing nut until the spring tensioner is relieved, then remove the forcing nut.
- Remove the compression rod and the coil spring from the vehicle.
- Place the insulator on the top of the spring. Position the spring into the lower arm spring pocket.
Make sure the spring pigtail is positioned between the two holes in the lower arm spring pocket.
- Position the spring into the upper spring seat in the crossmember.
- Insert the compression rod through the control arm and spring, then hook it to the upper plate. The upper plate is installed with the hooks facing the center of the vehicle.
- Tighten the forcing nut, position the lower arm into the crossmember, then install new lower arm-to-crossmember bolts and nuts, but do not tighten at this time.
- Remove the spring compressor tool from the vehicle.
- With a suitable jack, raise the suspension arm to a normal position. Tighten the lower arm-to-crossmember attaching nuts to 110-150 ft. lbs. (149-203 Nm). Remove the jack.
- Install the steering gear-to-crossmember bolts and nuts, if removed. Hold the bolts, then tighten to nuts to 90-100 ft. lbs. (122-136 Nm).
- Connect the stabilizer bar link to the lower suspension arm. Tighten the attaching nut to 8-12 ft. lbs. (12-16 Nm).
- Position the tie rod assembly into the steering spindle, then install the retaining nut. Tighten the nut to 35 ft. lbs. (47 Nm), and continue tightening the nut to align the next castellation with the cotter pin hole in the stud. Install a new cotter pin.
- Install the wheel and tire assembly, then carefully lower the vehicle.
See Figures 6, 7 and 8
The following procedures are used for removal and installation of the coil springs and MacPherson struts, since they are removed together; one can not be removed without the other.
- If equipped, remove plastic front shock cover cup at the front shock absorber mounting bracket.
- If equipped, remove the electronic automatic ride actuator and actuator mounting washer at top strut mount in engine compartment.
- Unfasten the three upper shock retaining nuts and collar plate/seal from the mounting studs in the engine compartment.
- Raise and safely support the vehicle with jackstands.
- Remove the tire and wheel assembly.
- Remove the lower strut mounting bolt and nut.
- Remove nut at the stabilizer link upper mounting stud.
- Separate the link from the front wheel spindle using Ball Joint Separator/Remover D88L-3006-A, or equivalent.
- Support lower control arm assembly with a transmission jack, or equivalent.
- Raise the control arm and spindle with the jack, until the stabilizer link can be completely separated from the wheel spindle. Position the stabilizer link out of the way.
- Remove the front wheel spindle-to-upper control arm ball joint attaching nut and bolt and discard.
- Carefully lower the jack to separate the spindle from the upper control arm. Do not allow the spindle to hang free, support it with a piece of wire or other means.
- Remove support from lower control arm and remove shock absorber/strut and spring assembly from vehicle.
- Position the shock absorber and upper mount assembly over the lower control arm. Insert the lower shock bolt into the lower control arm.
- Using a jack, raise the lower control arm and strut/shock absorber into position, aligning the upper strut mounting studs with the holes.
- Remove the wire holding the spindle and position the spindle to the upper control arm. Raise the lower control arm with the jack and attach the spindle to the upper control arm ball joint using a new attaching bolt and nut. Tighten the nut to 50-68 ft. lbs. (68-92 Nm).
- Position the stabilizer bar link and lower spindle assembly until link is in position to install the nut onto link. Tighten to 30-39 ft. lbs. (40-55 Nm).
- Remove the jack from the lower control arm.
- Install the lower strut nut, but do not tighten at this time.
- Install tire and wheel assembly, then tighten the lug nuts to 85-105 ft. lbs. (115-142 Nm), using a torque wrench.
- Carefully lower the vehicle, making sure the upper strut mounting studs are aligned with holes.
- Install the shock absorber housing seal and three nuts to the upper mounting studs. Tighten to 17-22 ft. lbs. (22-31 Nm).
- Install the washer, nut and install the electronic actuator, if equipped. Tighten the nut to 28-39 ft. lbs. (37-54 Nm).
- Install the plastic shock absorber/strut cover cup, if equipped.
- Neutralize the lower control arm bushings by pushing down on the front of the vehicle and releasing. Tighten the lower shock absorber/strut nut to 125-170 ft. lbs. (170-230 Nm).
