GM 15777767 Front Lower Control Arm Assembly

Start by loosening the wheel lug nuts and raising the vehicle on jackstands to remove the control arm on a 2WD model. Remove the wheel, and then coil spring. To a dealer or shop equipped with all needed tools, take your control arm for replacement of any balljoint and bushings if necessary. When installing the control arm, follow reversal of removal steps noting that once the vehicle is at normal ride height, every fastener should be tightened to correct torque specs. The other method starts by loosening the wheel lug nuts and raising the vehicle on jackstands. After removing the wheel, front splash shield might be required in some cases. Disconnect both shock absorber and stabilizer bar from lower control arm. Finally detach lower balljoint from steering knuckle to remove torsion bar followed by lower control arm itself. Replacing control arm may depend on inspections made on its bushings which should appear either worn out or damaged. Raise it into position after positioning it correctly as you insert washers alongside pivot bolts of control arm without tightening them completely yet. When inserting cotter pin through lower nut's hole put floor jack up until ball joint stud can be seen inside steering knuckle hole and then tighten ball joint stud nut properly using correct torque wrench value set. Connect stabilizer bar; mount shock absorber;install torsion bar; do not forget about connecting stabilizer bar again; install cover over this part too, if needed.The last phase involves installation of wheels plus lug bolts and lowering vehicles as well before final tightening of lugs according to specified levels of torque.Tighten rearward pivot bolt types for correlation between current spindle angle readings as well as their prespecified torques when shield becomes applicable.Correct vehicle's levels at lateral points followed by regulating torsion bar until equal elevation attained largely across its body frame sections otherwise referred as maintaining levelness in such cases.

Support the vehicle securely and remove the wheel.

Yes, there is another method of removal. Begin by loosening the wheel lug nuts and raising the vehicle on jackstands. Remove the wheel and front splash shield if applicable. Disconnect the shock absorber and stabilizer bar from the lower control arm. Remove the torsion bar and then the lower control arm by detaching the lower balljoint from the steering knuckle. Check the bushings for damage or wear, replacing the control arm if necessary.

Disconnect the upper balljoint from the steering knuckle.

To remove the control arm on a 2WD model, start by loosening the wheel lug nuts and raising the vehicle on jackstands. Remove the wheel and then the coil spring. Disconnect the lower balljoint and take the control arm to a dealer or properly equipped shop for any necessary replacements of the balljoint and bushings.

Mark the positions of the adjuster cams to the frame.

Position a floor jack with a wood block under the lower control arm.
