Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety glasses and gloves.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Remove the wheel on the affected side using a socket set.

3. Inspect and Replace Suspension Components

Control Arms:
- Visually inspect control arms for cracks or signs of wear.
- If damaged, remove the bolts securing the control arm and replace it with a new part.
- Torque the bolts to manufacturer specifications.
Struts/Shocks:
- Check struts or shocks for leaks or damage.
- If necessary, remove the strut assembly by unbolting it from the top mount and lower control arm.
- Replace with new struts/shocks and ensure proper alignment of all mounting points.
- Torque to manufacturer specifications.
Sway Bar Links:
- Inspect sway bar links for play or damage.
- Remove and replace any worn links.
- Ensure all fasteners are torqued properly.

4. Reassemble and Lower the Vehicle

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle back onto the ground and torque the lug nuts to specification.
