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, explore all options before starting any work. The strut body cannot be serviced and must be replaced if there is a problem. However, complete strut assemblies with springs may be available on an exchange basis, which can save time and effort. Before disassembling the vehicle, check the cost and availability of parts. To disassemble, remove the strut and spring assembly. Mount the strut clevis bracket portion in a vise and mark the components for reassembly. Install a spring compressor on the spring and compress it to relieve pressure from the upper mount. While holding the damper shaft, loosen the shaft nut with a socket. Remove the nut and upper mount, inspecting the pivot bearing and upper spring seat for damage. Lift the compressed spring from the assembly and remove the dust boot from the damper shaft. Slide the rubber bumper off the damper shaft and check the lower spring isolator for damage. To reassemble, extend the damper rod and install the rubber bumper. Put the dust boot onto the damper and carefully place the coil spring onto the damper, aligning it with the reference marks made during disassembly. Install the upper spring isolator and seat, followed by the upper mount, and tighten the nut on the damper shaft. Loosen the coil spring compressor until the top coil is properly seated against the upper spring seat and upper mount. Remove the tool from the coil spring and install the strut/spring assembly.
