If the struts or coil springs show signs of wear such as leaking fluid, loss of damping capability, or chipped, sagging, or cracked coil springs, it is important to explore all options before starting any work. These components are not serviceable and must be replaced if a problem arises. However, there may be the option to replace the entire strut assembly with springs on an exchange basis, which can save time and effort. Before disassembling the vehicle, it is recommended to check the cost and availability of parts. To disassemble, the strut and spring assembly should be removed and the upper strut cap cover should be unbolted to expose the damper shaft nut. A spring compressor should be used to relieve pressure from the upper spring seat, and the damper shaft nut should be unscrewed while holding the strut rod with a 45 Torx bit. The nut and upper mount and bearing should be removed and laid out in the order they were removed. The rubber portion of the upper mount should be checked for cracking and deterioration, and replaced if necessary. The upper spring seat should be removed from the damper shaft and the rubber portion should be inspected for cracking and hardness. The bearing in the spring seat should also be checked for smooth operation. The rubber bump stop should be slid off the damper shaft and checked for deterioration. The compressed spring should be carefully lifted from the assembly and set aside. To reassemble, the damper shaft should be extended and the rubber bump stop should be installed. The compressed coil spring should be placed onto the lower seat of the damper, with the end of the spring resting against the raised stop. The bearing and upper insulator/spring seat should be installed, followed by the upper mount and damper shaft nut, which should be tightened to the proper torque specifications. The spring compressor tool can then be removed, and the strut/spring assembly can be installed.

If the springs are being replaced, transfer the upper and lower spring pads to the new springs.
