REMOVAL & INSTALLATION
See Figures 1 through 8
- Raise and safely support the vehicle.
- Remove the wheel and tire assembly from the side of the vehicle requiring control arm replacement.
- Remove the steering knuckle-to-ball joint ball stud, clamping nut and bolt.
- Remove the 2 attaching links connecting the stabilizer bar to the lower control arms.
- Loosen, but do not remove the bolts holding the stabilizer bar retainers to the crossmember. Then, rotate the stabilizer bar and attaching links away from the lower control arms.
- Use a prybar to separate the steering knuckle from the ball joint stud. Be careful when separating the ball joint stud from the knuckle, so the seal does not become damaged.
- Remove the front lower control arm bushing-to-crossmember attaching nut and bolt. Remove the rear lower control arm-to-crossmember and frame rail attaching bolt. Then, remove the lower control arm from the crossmember.
- Position the lower control arm into the front crossmember. Install the rear lower control arm-to-crossmember and frame rail attaching bolt. Do NOT tighten the rear bolt at this time. Then, install the front lower control arm-to-crossmember nut and bolt.
- Tighten the front lower, then the rear control arm nut and bolt to 120 ft. lbs. (163 Nm).
- Place the ball joint stud into the steering knuckle. Install the steering knuckle-to-ball joint stud clamping bolt and nut. Tighten the bolt to 70 ft. lbs. (95 Nm).
- Assemble the stabilizer bar-to-lower control arm link assemblies and bushings.
- Rotate the stabilizer bar into position, installing the stabilizer bar links into the lower control arms. Install the top stabilizer bar link bushings and nuts. Do NOT tighten the link yet.
- Install the wheel and tire assembly.
- Carefully lower the vehicle so the suspension is supporting the total weight of the vehicle.
- Tighten the stabilizer bar-to-lower control arm links to 21 ft. lbs. (28 Nm).
- Tighten the stabilizer bar bushing retainer-to-crossmember attaching bolts to 21 ft. lbs. (28 Nm).
CONTROL ARM BUSHING REPLACEMENT
Front Isolator Bushing
See Figures 9, 10, 11 and 12
- Remove the front lower control arm from the vehicle.
- Mount a suitable C-clamp, C-422-F in a vise. Install bushing remover tool 6804 and bushing receiver tool 6758 on the C-clamp.
- Place the lower control arm on the special tools assembled for removal of the front isolator bushing, as shown in the accompanying figure. Be sure the tool are positioned and assembled properly on the C-clamp.
- Tighten the screw on the C-clamp to press the front bushing out of the lower control arm.
- Mount installer cup tool C-429-F on the C-clamp. Then, mount the bushing installer tool 6810 on the screw part of the C-clamp.
- Start the front bushing into the lower control arm by hand, making sure it is square with its mounting hole in the lower control arm. The bushing is to be installed in the lower control arm from the machined surface side of the lower control arm bushing hole.
- Install the lower control on the special tools. Make sure the tools are properly installed.
- Tighten the screw of the C-clamp, pressing the front bushing into the lower control arm until the special tool 6810 is flush on the machined surface of the lower control arm. This will correctly position the front bushing in the lower control arm.
- Install the lower control arm in the vehicle, as outlined earlier in this section.
Rear Isolator Bushing
See Figures 13, 14, 15 and 16
Removal and installation of the rear isolator bushing requires the use of an arbor press and a variety of special tools. Do NOT try to use a different procedure, other than the one given to replace the bushing.
- Remove the lower control arm from the vehicle.
- Position the lower control arm in an arbor press supported at the rear bushing using receiver cup tool 6756. Position the remover/installer tool 6758 on top of the rear control arm bushing, as shown in the accompanying illustration.
- Press the isolator bushing out of the lower control arm.
- Install the rear bushing into the lower control arm in the direction indicated in the accompanying figure. The rear bushing must be positioned in the lower control arm with the void in the bushing pointing toward the compression strut of the lower control arm, as shown in the accompanying figure.
- Place the lower control arm in an arbor press supported at the rear bushing hole using receiver cup 6756. Correctly position the remover/installer tool 6760 on top of the rear control arm bushing.
