You can Select Your Vehicle to check if 15777768 fits your vehicle.

Remove the upper control arm pivot bolts and nuts, and inspect the pivot bolt bushings for wear. Replace if necessary.

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.

To install the control arm using the alternative method, raise it into position and install the control arm pivot bolts, washers, and nuts without fully tightening them. Carefully raise the lower control arm with a floor jack until the balljoint stud can be inserted into the hole in the steering knuckle. Install the balljoint stud nut, tighten it to the proper torque, and install a new cotter pin. Install the torsion bar, connect the stabilizer bar, and install the shock absorber. Finally, install the wheel and lug nuts, lower the vehicle, and tighten the lug nuts to the torque specifications. Tighten the lower control arm pivot bolts to the correct torque specifications and install the splash shield if applicable. Measure the vehicle's ride height on each side and adjust the torsion bar accordingly until the vehicle sits level.

Start by loosening the wheel lug nuts and raising the front of the vehicle on jackstands.

Support the vehicle securely and remove the wheel.

Finally, install the air cleaner extension if it was removed.

Yes, there is another method of removal.
