1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a level surface and secure it with jack stands.
Disconnect the battery.

2. Inspect and Replace Bushings

Sub-steps:
1. Remove the wheel on the affected side using a socket set.
2. Locate the suspension bushings (control arm, sway bar).
3. Use a bushing removal tool or a press to remove old, worn bushings.
4. Clean the mounting surfaces with a wire brush.
5. Install new bushings, ensuring they are properly seated.
6. Reassemble the suspension components and torque bolts to manufacturer specifications.

3. Inspect and Replace Struts or Shocks (if necessary)

Sub-steps:
1. Remove the relevant wheel and locate the strut or shock absorber.
2. Disconnect any mounting hardware and remove the strut/shock from its mount.
3. Compare the old strut/shock with the new one to ensure proper fitment.
4. Install the new strut/shock and secure it with the appropriate hardware, torquing to specifications.
5. Reinstall the wheel and lower the vehicle.

4. Lubrication of moving parts

Sub-steps:
1. Apply a high-quality silicone spray or grease to all moving parts of the suspension, including bushings and joints.
2. Ensure thorough coverage and wipe off excess lubricant.
