Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Ensure the vehicle is stable before working underneath.

3. Inspect and Replace Components

Struts and Shocks:
- Remove the wheel to access the strut assembly.
- If struts are worn, use a socket set to unbolt the strut from the top and bottom mounts.
- Replace with new struts, ensuring proper alignment and torque to manufacturer specifications.
Control Arms:
- Check control arm bushings for wear.
- If damaged, remove the control arm by unbolting it from the frame and ball joint.
- Replace the control arm with a new part, and torque bolts to specifications.
Sway Bar Links:
- Inspect sway bar links for looseness or damage.
- Remove and replace any faulty sway bar links, ensuring they are properly tightened.

4. Reassemble and Lower the Vehicle

Reattach the wheel and lower the vehicle back to the ground.
Double-check all bolts and connections for tightness.

5. Final Inspection

Conduct a final visual inspection of the suspension components.
Ensure no tools or materials are left in the engine compartment or undercarriage.
