Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Use jack stands to secure the vehicle after raising it with a jack.

2. Inspect and Replace Suspension Components

Inspect Shock Absorbers/Struts:
- Remove the wheels using a socket set.
- Check for fluid leakage from the shock absorbers.
- If leaking, proceed to replace the shock absorbers.
Replacing Shock Absorbers:
- Use a socket set to remove the bolts securing the top and bottom of the shock absorber.
- Install the new shock absorber and torque bolts to manufacturer specifications (usually around 40-50 ft-lbs depending on the model).
Check Sway Bar Links:
- Inspect the sway bar links visually for play or damage.
- If damaged, remove the sway bar links using a wrench and replace with new ones.
Replacing Sway Bar Links:
- Remove the old link and install the new link.
- Torque the nuts to specifications (generally 30-40 ft-lbs).

3. Reassemble and Lower Vehicle

Reinstall the wheels and hand-tighten lug nuts.
Lower the vehicle and torque lug nuts to manufacturer specifications (typically 80-90 ft-lbs).

4. Final Inspection

Double-check all connections and components for proper installation.
Ensure the vehicle is safe for a test drive.
