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.

Before starting work, it's essential to check for signs of wear on the struts or coil springs, such as leaking fluid, loss of damping ability, or damaged coil springs. Explore repair options if issues are found.
