Before starting, check the cost and availability of parts. When disassembling the strut assembly, use a high-quality spring compressor as stated in the manufacturer's instructions. Remove the damper rod nut and inspect the upper bearing assembly. If it's not smooth or shows deterioration, replace it. To reassemble, install the rubber bumper and dust cover, place the coil spring onto the strut, and install the upper bearing assembly. Install and tighten the damper rod nut, remove the spring compressor tool, and install the strut/spring assembly.
