Solution

1. Preparation

Gather tools: socket set, torque wrench, jack stands, and a pry bar.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the vehicle.

2. Inspect and Replace Worn Components

Inspect Struts and Shocks:
- Remove the wheel using a socket set.
- Check for leaks or damage on struts or shocks.
- If damaged, remove the strut assembly by unbolting the upper and lower mounting points.
- Replace with new strut or shock absorber, ensuring proper torque specifications are followed (usually 20-30 ft-lbs).
Check Suspension Bushings:
- Inspect control arm bushings for deterioration or play.
- If worn, use a pry bar to remove the old bushing and press in the new one, ensuring it's seated properly.

3. Reassemble and Test

Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications (typically around 80-90 ft-lbs).
Reconnect the battery and lower the vehicle.
Perform a test drive over bumps to ensure the noise has been resolved.
