Loosen the wheel lug nuts, raise the front of the vehicle, and support it securely on jackstands before removing the wheel. For 2WD models, remove the spring and steering knuckle, then take off the pivot shaft nuts and pull the shaft out or drive it out with a hammer and drift punch to detach the lower arm. In 4WD models, remove the
Torsion Bar and unbolt the lower balljoint from the control arm, then take off the lower arm pivot nuts and shafts to lower the arm from the vehicle. Inspect the lower arm bushings for deterioration, cracking, and other damage; if replacement is needed, take the lower arm to an automotive machine shop for bushing replacement. For 2WD models, slip the pivot shaft into the cross member and through the control arm and bushing from the rear, using a soft-face hammer to tap it into place, then install the lock washers and nuts at the rear and the washer and nut at the front of the pivot shaft. Position the arm at normal ride height with a jack and tighten the nuts to the specified torque. For 4WD models, connect the balljoint to the lower arm and install the bolts and nuts, then position the arm at normal ride height and tighten the pivot shaft nuts to torque before installing the torsion bar. Finally, install the wheel and lug nuts, lower the vehicle, and tighten the lug nuts to the specified torque, then drive the vehicle to an alignment shop for a front end alignment check and adjustment if necessary.
