REMOVAL & INSTALLATION
- Raise the front of the vehicle and position safety stands under both sides of the jack pads, just to the rear of the lower arms.
- Remove the wheel and tire assembly.
- Disconnect the stabilizer bar link from the lower arm.
- If necessary for access, remove the disc brake caliper and wire it out of the way, then remove the rotor and dust shield.
- Disconnect the tie rod assembly from the steering spindle/knuckle using Tie Rod End Remover TOOL-3290-D or equivalent.
- Remove the steering gear bolts and position out of the way so the control arm bolt my be removed.
- Remove and discard the cotter pin from the ball joint stud nut, and loosen the ball joint nut one or two turns. Do NOT remove the nut at this time.
- Tap the spindle/knuckle boss sharply to relieve the stud pressure.
- 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 toward 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 onto the compressor tool until a drag on the nut is felt.
- Remove and discard the ball joint stud nut, and raise the entire stud and spindle/knuckle assembly. Wire it out of the way to obtain working room.
- Remove and discard the control arm-to-crossmember retaining nuts and bolts. The compressor tool may have to be tightened or loosened for easy bolt removal.
- Loosen the compression rod forcing nut until spring tension is relieved, then remove the forcing nut, lower control arm and coil spring.
- 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 and lower control arm onto the compression rod.
- Tighten the forcing nut and position the lower control arm into the crossmember.
- Install new lower control arm-to-crossmember bolts and nuts, but do not tighten yet.
- Remove the wire from the strut and spindle/knuckle assembly, pull the assembly down and attach to the ball joint stud. Install a new ball joint stud nut, but do not tighten yet.
- With a suitable jack, raise the control arm to a normal attitude position. Remove the compressor tool.
- With the jack still in place, tighten the lower arm-to-crossmember attaching nuts to 110-150 ft. lbs. (149-203 Nm).
- Tighten the ball joint stud nut to 100-120 ft. lbs. (149-203 Nm). Tighten the nut to align the holes, then install a new cotter pin. Carefully lower the vehicle and remove the jack.
- Install the brake dust shield, rotor and caliper, if removed.
- Install the steering gear-to-crossmember bolts and nuts, if removed. Hold the bolts and tighten them to 90-100 ft. lbs. (122-135 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.
- Connect the stabilizer bar link to the lower control arm. Tighten the attaching nut to 9-12 ft. lbs. (12-16 Nm).
- Install the wheel and tire assembly.
- Remove the safety stands and carefully lower the vehicle.
See Figure 1
- Raise and safely support vehicle on jackstands.
- Remove the tire and wheel assembly.
- Loosen the lower ball joint nut 3 or 4 turns.
- Rap on spindle with a heavy hammer, just enough to separate the ball joint from the spindle. Leave the nut on the ball joint.
- Support the spindle by a wire or other means to prevent excessive sagging of the upper control arm.
- Matchmark the position of the camber adjustment cam.
- Hold the lower control arm strut by the flats with a wrench, then remove the nut retaining the lower control arm strut to the control arm bushing joint and discard.
- Remove the lower shock attaching bolt and nut.
- Remove the pivot (camber) bolt and nut.
- Remove the nut from the lower ball joint, then remove lower control arm.
- Position the lower control arm in vehicle and loosely install the pivot (camber) bolt and nut.
- Install the tension strut insulator bushings and loosely install the attaching nut.
- Install the ball joint nut loosely.
- Install the lower shock bolt and nut but do not tighten at this time.
- Tighten the ball joint nut to 83-113 ft. lbs. (113-153 Nm) and install a new cotter pin.
- Tighten the tension strut control arm nut to 83-113 ft. lbs. (113-153 Nm).
- Remove the wire or other type of support holding the spindle.
- Install the tire and wheel assembly. Tighten the lug nuts, with a torque wrench, to 85-105 ft. lbs. (115-142 Nm).
- Carefully lower the vehicle.
- Push down on the front of the vehicle and release to neutralize the suspension. Tighten the lower shock nut to 125-170 ft. lbs. (170-230 Nm).
- Align the camber marks at the pivot bolt and tighten nut to 83-113 ft. lbs. (113-153 Nm).
If the lower control arm was replaced, the alignment must be checked.
CONTROL ARM BUSHING REPLACEMENT
See Figures 2 and 3
- Remove the lower control arm as outlined previously.
- Press out the lower control arm mounting bolt bushing with Bushing Remover T78P-5638-A5, Receiving Cup T78P-5638-A4 and Forcing Screw T78P-5638-A1.
- Install a new lower control arm bushing into the lower control arm from the front of the control arm using Bushing Replacers T78P-5638-A and T89P-5493-B, Forcing Screw T78P-5638-A1 and Forcing Screw Washer T79P-5638-A6. Turn the Forcing Screw until it bottoms.
- Install the lower control arm, as outlined earlier in this section.
- Have the front alignment checked by a reputable repair shop.
