Before working on worn struts or coil springs, consider replacement options. Check part availability and cost before disassembling the vehicle. To disassemble, remove and mount the assembly in a vise. Use a spring compressor to relieve pressure and unscrew the damper shaft nut. Check rubber parts for wear and replace them if needed. Carefully set aside the compressed spring. To reassemble, extend the damper rod and install the rubber bump stop and dust boot, then place the compressed coil spring onto the lower seat of the damper. Install the upper insulator, spring seat, and upper mount, tightening to the specified torque. Remove the spring compressor tool and install the assembly.

Check the strut for leaking fluid, dents, cracks, and other damage. Inspect the coil spring for chips or cracks in the coating, and the spring seat for cuts or deterioration. If any issues are found, proceed with the strut disassembly procedure.

Remove the shock absorber upper mounting bolts, discarding them as new ones will be needed during installation.

Yes, on specific models, remove the control arm-to-strut yoke nut and bolt, and disconnect the tie-rod end from the steering knuckle. Support the lower control arm if needed.
