To disassemble the strut and spring assembly, you need to mount the strut clevis bracket portion in a vise and mark the components for reassembly. Then, install a spring compressor on the spring and compress it to relieve pressure from the upper mount. While holding the damper shaft, loosen the shaft nut with a socket. Remove the nut and upper mount, inspecting the pivot bearing and upper spring seat for damage. Lift the compressed spring from the assembly and remove the dust boot from the damper shaft. Slide the rubber bumper off the damper shaft and check the lower spring isolator for damage.

To simulate normal ride height, the rear suspension should be raised with a floor jack positioned under the knuckle.

To reassemble the strut and spring assembly, you need to extend the damper rod and install the rubber bumper. Put the dust boot onto the damper and carefully place the coil spring onto the damper, aligning it with the reference marks made during disassembly. Install the upper spring isolator and seat, followed by the upper mount, and tighten the nut on the damper shaft. Loosen the coil spring compressor until the top coil is properly seated against the upper spring seat and upper mount. Finally, remove the tool from the coil spring and install the strut/spring assembly.

Compress the coil spring with a spring compressor, following the tool manufacturer's instructions. Compress the spring until tension is removed from the upper bracket.

Remove the shock through the bottom of the spring and inspect all parts for damage. Install the parts on the new shock in the correct order. Install the washer and damper shaft nut, tightening it while holding the damper shaft with a wrench.

If you plan on removing the springs and overhauling the shock unit, follow the appropriate procedures.
