Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Use jack stands to secure the vehicle after raising it.

2. Inspect and Replace Worn Components

Suspension Components:
1. Remove the wheel on the affected side using a socket set.
2. Inspect the struts, sway bar links, and control arms for any signs of damage or wear.
3. If any components are found to be defective, proceed to replace them:
  - For struts, detach the top mounting bolts and lower bolts, replace with new struts, and torque to manufacturer specifications (typically around 40-50 ft-lbs).
  - For sway bar links, remove the nuts and replace with new links.
  - For control arms, remove the bolts securing them to the frame and replace with new control arms.

3. Reassemble and Test

Reinstall the wheel and torque the lug nuts to 76 ft-lbs.
Lower the vehicle and perform a bounce test again to check for any remaining noise.
Test drive the vehicle over bumps to confirm the noise has been resolved.
