If the struts or coil springs show signs of wear such as leaking fluid, loss of damping capability, or physical damage like chips or cracks, consider 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, so check the cost and availability of parts before disassembling the vehicle. To disassemble, remove the strut and spring assembly, mount it in a vise lined with wood or rags to prevent damage, and avoid excessive tightening. Following the tool manufacturer's instructions, install a spring compressor to relieve pressure from the upper spring seat, which can be verified by wiggling the spring. Remove the piston rod nut and the upper suspension support, inspecting the bearing for smooth operation and checking the rubber for any signs of 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 set it aside safely. Slide the dust boot off the piston rod and check the lower insulator for wear, replacing it if necessary. For reassembly, if replacing the lower insulator, position it correctly and extend the damper rod to install 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, aligning the marks or arrows correctly, then install the dust seal and suspension support to the piston rod, tightening the nut to the specified torque before reinstalling the strut/shock absorber and coil spring assembly.
