Q: How to assembly and disassembly of a front strut and rear shock absorber/coil assembly on Toyota Prius?
A: The assembly and disassembly of a front strut is demonstrated, with the rear shock absorber/coil assembly being similar yet slightly different. If struts or coil springs show signs of wear such as leaking fluid, loss of damping capability, or physical damage, consider all options before proceeding, 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 disassembly. To disassemble, remove the strut assembly and mount it in a vise lined with wood or rags to avoid damage, ensuring the vise is not overly tightened. Install a spring compressor according to the manufacturer's instructions to relieve pressure from the upper spring seat or spring bracket, verifying this by wiggling the spring. Mark the positions of the upper and lower spring seats and suspension support, then loosen and remove the damper shaft nut, followed by the suspension support or spring bracket. Inspect the bearing in the suspension support for smooth operation and check the rubber for deterioration, replacing as necessary. Lift the spring seat and upper insulator from the damper shaft, checking the rubber spring seat for damage. Carefully remove the compressed spring from the assembly, keeping it pointed away from your body, and slide off the rubber bumper. Check the lower insulator for wear and replace if needed. For reassembly, if replacing the lower insulator, position it correctly and extend the damper rod to install the rubber bumper. Place the coil spring onto the lower insulator, ensuring the end fits properly. Install the upper insulator and spring seat, aligning the flats on the damper shaft with those in the spring seat. Attach the dust seal and suspension support, ensuring all previously marked positions align, then install a new nut and tighten it. Finally, reinstall the strut assembly or rear shock absorber/coil spring as required.
