Solution

1. Preparation

Gather tools: jack, jack stands, socket set, torque wrench, and pry bar.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel on the side where the noise is more pronounced to access suspension components.

3. Inspect and Replace Components

Struts/Shocks:
- Inspect for oil leaks and physical damage.
- If damaged, remove the strut/shock by unbolting it from the top mount and lower control arm.
- Replace with a new strut/shock, ensuring it is torqued to manufacturer specifications (typically around 50-70 ft-lbs).
Sway Bar Links:
- Check for looseness or damage.
- If necessary, unbolt the sway bar link from the sway bar and control arm.
- Install a new sway bar link and torque to specifications (typically 20-25 ft-lbs).
Control Arm Bushings:
- Inspect for cracks or excessive wear.
- If replacement is needed, unbolt the control arm from the chassis and the ball joint.
- Replace bushings using a press if needed and reinstall the control arm, torquing bolts to specifications.

4. Reassemble and Lower Vehicle

Reinstall the wheel and lower the vehicle from the jack stands.
Tighten lug nuts to the manufacturer's specifications (usually 80-100 ft-lbs).
