Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect and Tighten Components

Sub-steps:
1. Using a socket set, check and tighten all suspension bolts, including those on the strut assembly and sway bar links.
2. Inspect the lower control arm and trailing arm bolts for tightness.

3. Replace Worn Components

Sub-steps:
1. If any sway bar links or bushings are found to be damaged, remove the old components using a wrench and replace them with new parts.
2. For struts or shock absorbers that are leaking or damaged, remove them by first unbolting the top mount and then the lower mount.
3. Install new struts or shocks, ensuring they are torqued to the manufacturer’s specifications (typically around 15-20 ft-lbs for bolts).

4. Reassemble and Lower Vehicle

Sub-steps:
1. Reinstall any components removed during the inspection, ensuring all fasteners are tightened.
2. Lower the vehicle back to the ground and remove the jack stands.

5. Final Checks
