Solution

1. Preparation

Gather tools and safety equipment.
Park the vehicle on a flat surface and engage the parking brake.

2. Raise the Vehicle

Use a jack to lift the vehicle and support it securely on jack stands.
Remove the wheels for easier access to suspension components.

3. Inspect Suspension Components

Check struts and shocks for any fluid leaks or signs of wear.
Inspect control arms and bushings for cracks or deterioration.
Look for any loose bolts or fasteners and tighten them to manufacturer specifications.

4. Replace Damaged Components

If any components are found to be damaged or excessively worn, replace them.
- For struts or shocks, remove the top mounting bolts, detach the lower mounting bolts, and replace with new units.
- For control arms, remove the bolts securing them to the frame and replace with new.

5. Reassemble and Lower Vehicle

Reinstall the wheels and lower the vehicle back to the ground.
Torque the lug nuts to the manufacturer's specifications.
