Solution

1. Preparation

Gather tools: socket set, torque wrench, jack stands, and pry bar.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Suspension Components

Raise the Vehicle
- Use a jack to lift the vehicle securely and place jack stands under the frame for safety.
Remove Wheel
- Use a socket set to take off the lug nuts and remove the wheel to access suspension components.
Examine Struts and Shocks
- Check for any leaks or damage. If damaged, remove the strut or shock by unbolting it from the top and bottom mounts. Replace with new components and torque the bolts to manufacturer specifications.
Check Sway Bar Links
- Inspect the sway bar links for any signs of wear. If damaged, use a socket set to remove and replace them. Ensure the new links are torqued properly.
Inspect Control Arms and Ball Joints
- Use a pry bar to check for play in the control arms and ball joints. If either is worn, remove them and replace with new parts, ensuring all bolts are torqued to specification.

3. Reassemble and Lower Vehicle

Reinstall Wheel
- Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the Vehicle
- Carefully remove the jack stands and lower the vehicle back to the ground.
Torque Lug Nuts
- Use a torque wrench to tighten the lug nuts to the specified torque for your model.
