When doing this, one must use a spring compressor, which can usually be rented from auto parts stores or equipment yards. If the struts or coil springs seem damaged by leaking fluid, failure to dampen fast enough, or broken coil springs, it is important to consider repair options before proceeding. Problems require replacing strut and coil spring assemblies that cannot be repaired. Full strut assemblies with springs may be available for exchange and will save you time. Before disassembling: part availability and cost should be considered (John 2002). The first step is to remove the strut and spring assembly; however, care should be taken while fastening the strut clevis bracket on a vise so as not to destroy other parts of it using wood or rags. Follow all of the spring's manufacturer's instructions in order to install a spring compressor on it until compressing everything above the upper spring seat completely relieves any pressure. Use a socket wrench to grip the damper shaft and take off the nut from it and also remove the damper shaft itself together with an upper mount. Keep all taken-apart pieces arranged in their proper sequence and inspect rubber part of upper mount for cracks or deterioration-replace if necessary (John 2002). Take away upper spring seal after checking the rubber part for wear and tear and bearing for smooth functioning replacing as required (John 2002). Slip off the bump stop made of rubber from damper shaft and check its condition-replace if necessary (John 2002). Carefully lift out compressed spring from assembly making sure you label springs as LEFT & RIGHT if removing both struts (John 2002). For reassembly: extend damper rod, put on rubber bump stop, drop compressed coil spring onto lower seat of damper making sure end sits against raised stop (John 2002). Put on top insulator; place spring seat; put on top mount; then mount nut, tight to specified torque (John 2002). Finally, take off the spring compressor tool and replace the strut/spring assembly.

The first thing to do when replacing worn shock absorbers or coil springs is checking for typical signs of wear such as fluid leaks, loss of damping or damaged coil springs. Think about replacement options and check the parts availability. The shock absorber/coil spring assembly should be removed and the pressure on the upper spring seat released by means of a spring compressor. At this stage hold the shock damper shaft in one hand while the retaining nut is removed with the other hand. Other components like upper cup, insulator, top carrier, lower insulator, sleeve, lower cup and bump stop have to be removed as well. If you are replacing the spring, carefully release it from the compressor. Inspect all components for wear and replace as needed. When working with both assemblies, remember to label them left and right springs. The shock should be inspected for fluid leaks, pitting on the damper shaft or damage to the shock body. Its operation has to be tested for smooth uninterrupted resistance. Replace it in case of any found issues. The extended shock damper shaft should have rubber bump stop fitted onto it as well as lower cup, lower insulator and sleeve Install the compressed coil spring on lower seat ensuring that it contacts at its bottom most part Position upper spring seat on top carrier then install top carrier on shock damper shaft with coil spring such that the end of spring fits into upper seat's recessed portion When installing tightened upper insulator upon cup then retain nut Remove the compressing tool finally reinstalling assembly of absorber/shock coil.

After reassembling the shock absorber/coil spring assembly, you should remove the spring compressor.

Remove the shock carrier's lower mounting bolts.

A spring compressor is necessary for this procedure, which can typically be rented from auto parts stores or equipment yards.

Have the front wheel alignment checked and, if necessary, adjusted.

Support the strut and spring assembly with one hand and remove the upper mounting nut.

Chock the front wheels to keep the vehicle from rolling.
