Solution

1. Preparation

Tools Needed: Jack and jack stands, socket set, torque wrench, pry bar, safety glasses, gloves.
Ensure the vehicle is parked on a level surface and the ignition is off.
Wear safety glasses and gloves for protection.

2. Raise the Vehicle

Use a jack to lift the vehicle at designated lift points.
Securely place jack stands under the vehicle to ensure stability.

3. Inspect and Replace Damaged Components

Struts/Shocks:
- Remove the wheels for better access.
- Inspect struts/shocks for leaks or physical damage.
- If damaged, unbolt the strut/shock from the top and bottom mounting points using a socket set.
- Replace with OEM or equivalent parts and torque bolts to manufacturer specifications.
Bushings and Mounts:
- Check control arm bushings for cracking or deterioration.
- If worn, use a pry bar to remove old bushings and press in new ones.

4. Tighten Loose Components

Inspect all suspension bolts and fasteners.
Use a torque wrench to tighten any loose bolts to the manufacturer's specifications.

5. Reassemble and Lower the Vehicle

Reinstall the wheels and lower the vehicle back to the ground.
Perform a final check to ensure all tools are removed and components are secured.
