Loosen the wheel lug nuts, raise the front of the vehicle, and support it securely on jackstands. Apply the parking brake and block the rear wheels to prevent rolling off the jackstands, then remove the wheel. If only one control arm is being removed, disconnect that end of the stabilizer bar; if both are being removed, disconnect both ends. Remove the balljoint stud's castellated nut and cotter pin, then separate the balljoint from the control arm using a separation tool or a large pry bar, taking care not to overextend the inner CV joint. Remove the two control arm pivot bolts and detach the control arm. Inspect the control arm bushings for hardening, excessive wear, and cracks; if they are worn or deteriorated, take the control arm to a dealer service department or repair shop for replacement. Position the control arm in the suspension support and install the pivot bolts without fully tightening them. Insert the balljoint stud into the control arm, install the castellated nut, and tighten it to the specified torque, adjusting if necessary to align the cotter pin hole, then install a new cotter pin. Use a floor jack under the balljoint to raise it to simulate normal ride height and tighten the control arm pivot bolts to the specified torque. Install the stabilizer bar-to-control arm bolt, spacer, bushings, and washers, tightening the nut to the specified torque. Finally, install the wheel, lower the vehicle, and tighten the lug nuts to the specified torque, then drive to a dealer service department or alignment shop for a front wheel alignment check and adjustment if needed.
