You can Select Your Vehicle to check if 4656163 fits your vehicle.

Check for leaking fluid, dents, cracks, and other obvious damage. Also, check the coil spring for chips and corrosion. Replace any damaged components.

Check the shock absorber for rod binding, and inspect the shock mount, upper spring seat/isolator, and coil spring for any cracks, distortion, deterioration, rips, chips, or corrosion. Replace any worn or defective components.

To remove the shock absorber, start by rolling back the trunk carpeting and removing the plastic cap to access the upper shock mounting bolts. Then, lift the carpeting and unsnap the plastic cover to remove the two upper mounting nuts. Next, loosen the rear wheel lug nuts, raise the vehicle, and support it on jackstands. Remove the rear wheels and the shock absorber lower mounting bolt from the rear knuckle. Push down on the rear suspension and pull the shock away from the knuckle to remove it. To inspect the shock absorber, check for leaking fluid, dents, cracks, and other damage. Also, check the coil spring for chips or cracks and inspect the spring seat, rubber isolators, bushings, dust shield, and jounce bumper for any deterioration. Replace any components as necessary. For component replacement, mount the shock assembly in a vise and mark it as right or left. Use a spring compressor to relieve pressure from the upper mount, then unscrew the damper rod nut and remove the washer. Remove the isolator bushing, shock absorber mount, spring isolator, rod washer, and dust boot. Lift the coil spring off the shock absorber and remove the jounce bumper, collar, and coil spring isolator. Reassemble the shock absorber in the reverse order of removal, making sure to install the sleeve with the undercut side facing downward and the top washer with the "TOP" stamp facing upward. When reinstalling the spring, align the studs at the top of the mounting plate with the hole in the bottom clevis bracket. Finally, for installation, guide the shock absorber into place, insert the upper mounting studs through the holes in the shock tower, and tighten the nuts. Connect the lower end of the shock absorber to the knuckle and tighten the bolt/nut. Install the wheels, lower the vehicle, and tighten the lug nuts. Finally, tighten the upper mounting nuts and install the cap.
