If the struts or coil springs show signs of wear such as leaking fluid, loss of damping capability, or physical damage, explore all options before starting any work, as strut/shock absorber assemblies are not serviceable and must be replaced if issues arise. Strut assemblies with springs may be available on an exchange basis, which can save time and effort. Always check the cost and availability of parts prior to disassembling the vehicle. Disassembling a strut can be dangerous, so focus on the task to avoid serious injury, using only a high-quality spring compressor and adhering to the manufacturer's instructions. After removing the coil spring from the strut assembly, place it in a safe area. To disassemble, remove the strut and spring assembly, mount it in a vise lined with wood or rags, and avoid excessive tightening. Install the spring compressor according to the manufacturer's instructions and compress the spring until all pressure is relieved from the upper spring seat, which can be verified by wiggling the spring. Remove the piston rod nut and the upper mount, inspecting the bearing for smooth operation and checking the rubber portion for deterioration. Lift the spring seat and upper insulator from the piston rod, checking the rubber spring seat for damage. Carefully lift the compressed spring from the assembly, ensuring the ends are pointed away from your body, and slide the dust boot off the piston rod. Check the lower insulator for wear and replace it if necessary. For reassembly, if replacing the lower insulator, position it correctly and extend the damper rod to its full length before installing the dust boot. Place the coil spring onto the lower insulator, ensuring the end fits into the recessed portion. Install the upper insulator and spring seat, ensuring the cutout on the spring seat faces outward, then install the dust seal and upper mount to the piston rod. Finally, install the nut and tighten it to the specified torque before reattaching the strut/shock absorber and coil spring assembly.

Guide the brake hose through its bracket in the strut and install the retaining clip.

Position a floor jack under the lower rear suspension arm and raise the suspension arm slightly.
