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. The strut/shock absorber assemblies cannot be serviced and must be replaced if there is a problem. However, there may be strut assemblies available 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 mounted in a vise, taking care to protect the unit. A spring compressor should be installed following the manufacturer's instructions to relieve force from the upper spring seat. The damper shaft nut should be loosened and removed, along with the suspension support. The bearing and rubber portion of the suspension support should be inspected and replaced if necessary. The top mount assembly and upper spring seat should be removed, checking for cracking and replacing if needed. The compressed spring should be carefully lifted and set aside. The dust boot and rubber bumper should be removed, and the lower insulator should be checked for wear and replaced if necessary. To reassemble, if the lower insulator is being replaced, it should be set into position with the dropped portion seated properly. The dust boot should be replaced, and the damper rod should be extended and the rubber bumper installed. The coil spring should be placed onto the lower insulator, with the end resting properly. The upper spring seat and top mount should be installed, aligning them correctly. The damper nut should be tightened to the specified torque, and the spring compressor tool can be removed.
