Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Raise the Vehicle

Use a jack to lift the vehicle and support it with jack stands.
Remove the wheels for better access to suspension components.

3. Inspect and Replace Worn Components

Sway Bar Links:
- Remove the sway bar link bolts using a socket set.
- Replace with new sway bar links if they are worn or damaged.
- Torque bolts to manufacturer specifications (typically around 40-50 ft-lbs).
Struts and Shocks:
- Remove the strut assembly by unbolting it from the top and bottom (note the torque specifications).
- Inspect for any signs of oil leakage or physical damage.
- If damaged, replace with new struts/shocks and reassemble, ensuring all bolts are torqued correctly.
Bushings:
- Inspect all bushings for cracks or degradation.
- Replace any worn bushings with new ones, ensuring proper alignment during installation.

4. Reassemble and Lower the Vehicle

Reinstall the wheels and lower the vehicle from the jack stands.
Ensure all components are tightened to manufacturer specifications.
