Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety goggles and gloves.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Ensure all weight is off the suspension for inspection.

3. Inspect and Replace Suspension Components

Inspect Struts/Shocks:
- Remove the wheel to access the strut assembly.
- Check for oil leakage or physical damage.
- If defective, remove the strut by unbolting from the top mount and lower knuckle.
- Replace with new struts/shocks, ensuring proper torque specifications (typically 35-50 ft-lbs for strut bolts).
Inspect Sway Bar Links:
- Check the sway bar links for play or wear.
- Remove the links if damaged and replace with new units, torquing to manufacturer specifications.
Inspect Control Arms:
- Look for any bushings that are cracked or worn.
- If necessary, unbolt the control arm and replace it, ensuring all bolts are torqued correctly.

4. Reassemble and Lower Vehicle

Reinstall the wheel and lower the vehicle back to the ground.
Tighten lug nuts to manufacturer specifications (typically 80-100 ft-lbs).

5. Final Check

Perform a bounce test again to ensure the suspension is functioning correctly.
Take the vehicle for a test drive to confirm the noise has been resolved.
