Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Place wheel chocks in front of the front wheels for safety.

2. Remove Rear Wheel

Loosen lug nuts with a socket wrench.
Raise the rear of the vehicle using a jack and secure it on jack stands.
Remove the rear wheel to access the suspension components.

3. Replace Shocks/Struts

Tools Required: Socket set, wrench set, spring compressor (if applicable).
Remove the bolts securing the shock/strut at the bottom and top mounts.
Carefully detach the old shock/strut from the vehicle.
Install the new shock/strut, ensuring it is aligned properly.
Torque the mounting bolts to the manufacturer’s specifications (consult a repair manual for exact torque values).

4. Inspect and Replace Bushings (if necessary)

Check the condition of the suspension bushings for signs of cracking or wear.
If bushings need replacement, use appropriate tools to remove the old bushings.
Install new bushings and ensure they are seated correctly.

5. Inspect and Replace Springs (if necessary)

If coil springs are damaged or sagging, remove them using a spring compressor.
Replace with new springs as needed, ensuring correct orientation and installation.

6. Reassemble and Lower Vehicle

Reattach the wheel and hand-tighten the lug nuts.
