REMOVAL & INSTALLATION
See Figures 1 through 6
Be sure new wheel hub retainer nuts, tie rod end castellated nuts, stabilizer bar link nuts and knuckle-to-strut pinch bolt/nuts are available. These parts lose their torque holding/retention capabilities during removal and must not be reused.
- Turn the ignition switch to the OFF position. Leave the steering column in the UNLOCKED position.
- With all four wheels on the ground, remove the wheel hub retainer nut. Discard the nut.
On the SHO vehicles:
- Detach the height sensor wiring connector.
- Remove the wiring harness from the routing clip on the front shock absorber.
- Remove air suspension height sensor from the height sensor ball studs.
- Loosen the three top mount-to-strut tower nuts, but do not remove the nuts at this time.
- Raise and safely support the vehicle.
- Remove the wheel and tire assembly.
When raising the vehicle, do not lift by using the lower control arms.
- Remove the disc brake caliper. Hang the caliper out of the work area with wire to prevent damage to the brake hose.
- Remove the disc brake rotor.
- Remove the anti-lock brake sensor wiring harness clip and the mounting screw from the brake hose bracket on the strut assembly. Move the anti-lock brake sensor aside.
- Remove the cotter pin and the castellated nut from the tie rod end. Discard the cotter pin and nut.
- Using Removal tool 3290-D, or equivalent and Adapter tool T81P-3504-W or equivalent, separate the tie rod end from the steering knuckle.
- On SHO vehicles, remove the vinyl cover from the upper link stud.
- Remove the sway bar (stabilizer bar) link nut and link from the strut. Discard the link nut.
- Remove and discard the lower ball joint retaining nut. Using Ball Joint Remover T96P-3010-A or equivalent, separate the ball joint from the lower control arm.
- Using Spring Compressor 164-R-3571 or equivalent, compress the coil spring until the ball joint clears the lower arm.
- Remove the pinch bolt and nut from the bottom of the steering knuckle. It may be necessary to use a drift punch to remove the bolt. Discard the pinch bolt and nut.
- Separate the halfshaft from the wheel hub using Front Hub Remover/Replacer T81P-1104-C or equivalent and the required adapters.
- Support the halfshaft with wire in a level position to prevent it from hanging by the inner CV-joint.
- Remove the three top mount-to-strut tower nuts while supporting the strut. Lower the strut assembly from the vehicle.
- Install the strut assembly with the spring compressor installed to the vehicle and install the three top mount-to-strut tower nuts loosely.
Further compress the coil spring if added clearance is required for installation.
- Install the steering knuckle and hub assembly to the strut. Install a new pinch bolt and nut. Tighten to 73-97 ft. lbs. (98-132 Nm).
- Install the halfshaft into the hub using care to align the splines.
- Install the sway bar link to the strut and install a new sway bar link nut. Tighten to 55-75 ft. lbs. (75-101 Nm).
- On SHO vehicles, install the vinyl cover to the upper link stud.
- Install the tie rod end onto the steering knuckle using a new castellated nut. Tighten the nut to 35-46 ft. lbs. (47-63 Nm). Continue to tighten the nut until a slot lines up with the opening in the tie rod end stud and install a new cotter pin.
- Install the anti-lock brake sensor wiring routing clip and tighten the brake hose bracket mounting screw.
On the SHO vehicles:
- Install air suspension height sensor to the height sensor ball studs.
- Install the wiring harness to the routing clip on the front shock absorber.
- Attach the height sensor wiring connector.
- Install the disc brake rotor and caliper. Tighten the caliper anchor bracket bolts to 65-87 ft. lbs. (88-118 Nm).
- Install the wheel and tire assembly. Tighten the lug nuts to 85-105 ft. lbs. (115-142 Nm).
- Tighten the three top mount-to-shock tower nuts to 22-29 ft. lbs. (30-40 Nm).
- Lower the vehicle.
- Install a new wheel hub retainer nut. Tighten the nut to 170-202 ft. lbs. (230-275 Nm).
- Pump the brake pedal several times prior to moving the vehicle, to position the brake pads.
- Road test the vehicle and check for proper operation.
See Figures 7 and 8
- Remove the strut from the vehicle.
- Compress the coil spring using a suitable spring compressor until the spring comes away from the seat.
- Remove the large center nut and slowly release the spring compressor.
- Remove the upper bearing from the strut assembly.
- Remove the spring from the strut assembly.
- Remove the lower spring insulator from the strut.
- If replacing the strut, transfer any necessary components from the old strut.
- Install the lower spring insulator onto the strut.
- Compress the spring and install it on the strut.
- Install the lower washer and upper bearing assembly.
- Install the upper washer and a new nut. Tighten the nut to 39-53 ft. lbs. (53-72 Nm) while holding the rod with a T-50 size Torx® socket.
- Install the strut assembly in the vehicle.
