GMC 22868629 Control Arm

To remove the component, first loosen the wheel lug nuts, raise the vehicle, and securely support it on jackstands placed under the frame rails before removing the wheel. Next, disconnect the stabilizer bar link from the control arm and remove the shock absorber lower mounting fasteners. For 4WD models, remove the drive axle, and if working on a model with torsion bar front suspension, remove the torsion bar. Use rope or wire to support the upper control arm and steering knuckle from the top of the shock absorber. To disconnect the lower control arm from the steering knuckle, loosen the ball joint nut a few turns without removing it, then install a ball joint separator to break the ball joint loose from the knuckle; a hammer and drift can also be used if necessary. After removing the nut, take out the lower control arm pivot bolts and nuts, noting the installation direction, and pull the lower arm from its frame brackets. For installation, position the arm in the frame brackets and install the bolts and nuts without tightening them yet. Attach the ball joint to the steering knuckle, install a new nut, and tighten it to the specified torque. The remainder of the installation follows the reverse order of removal, ensuring all fasteners are tightened to the correct torque values. The pivot bolt nuts should be tightened with the vehicle at normal ride height, which can be done after lowering the vehicle or by simulating the height with a floor jack. Finally, install the wheel and lug nuts, lower the vehicle, and tighten the lug nuts to the specified torque. If working on a model with torsion bar front suspension, check and adjust the ride height, and have the front end alignment checked and adjusted if necessary.
