Check the strut 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 with the strut disassembly procedure.

Remove the shock absorber upper mounting bolts, discarding them as new ones will be needed during installation.

Yes, on specific models, remove the control arm-to-strut yoke nut and bolt, and disconnect the tie-rod end from the steering knuckle. Support the lower control arm if needed.

If the struts or coil springs show signs of wear such as leaking fluid, loss of damping capability, 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 strut assemblies available 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 mounted in a vise. 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 shaft in place. The nut and upper mount should be removed and laid out in the order they were removed. The rubber parts of the upper mount and spring seat should be checked for cracking and deterioration, and replaced if necessary. The dust boot and rubber bump stop should be slid off the damper shaft, and the bump stop should be checked for deterioration. The compressed spring should be carefully lifted and set aside. To reassemble, the damper rod should be extended and the rubber bump stop and dust boot 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 upper insulator and spring seat should be installed, followed by the upper mount and mounting nut, which should be tightened to the specified torque. The spring compressor tool can then be removed, and the strut/spring assembly can be installed.
