To remove the strut, start by loosening the wheel lug nuts and raising the front of the vehicle on jackstands. Mark the relationship of the strut to the knuckle for installation reference. Remove the strut-to-knuckle nuts and bolts, being careful not to damage the brake hose or overextend the inner CV joint. Support the strut and spring assembly while removing the upper mounting nuts, then remove the assembly from the fender well. To inspect the strut, check for leaking fluid, dents, cracks, and other damage. Inspect the coil spring for chips or cracks in the coating and the spring seat for cuts or deterioration. If any issues are found, proceed to the strut disassembly procedure. For installation, guide the strut assembly back into the fender well, aligning the index mark made earlier. Insert the upper mounting studs through the holes in the strut tower and secure with nuts. Slide the steering knuckle into the strut flange and install the bolts and nuts, aligning the marks. Install the wheel, lower the vehicle, and tighten the lug nuts. Finally, tighten the upper mounting nuts, have the front wheel alignment checked, and make any necessary adjustments.

Signs of wear may include leaking fluid, loss of damping capability, chipped, sagging, or cracked coil springs.

To install the strut, guide the knuckle into the strut range and position the upper part of the strut to mount it to the body.

To remove the strut, start by moving the side trim in the trunk compartment to expose the strut upper mounting fasteners. Loosen the mounting fasteners without removing them and pull off the rubber cap on top of the strut if it is equipped. Loosen the rear wheel lug nuts, block the front wheels, and raise the rear of the vehicle on jackstands. Remove the rear wheels and detach the stabilizer bar link from the strut. Mark the relationship of the strut to the knuckle for reference during installation. Remove the strut-to-knuckle nuts by holding the oval-shaped bolt heads with a wrench and striking the end with a hammer to push them out of the knuckle and strut. Separate the strut from the rear knuckle, remove the upper mounting nuts, and secure the rear knuckle to prevent damage.

The rubber portion of the upper mount should be checked for cracking and deterioration, and replaced if necessary.
