Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery for safety if working on electrical components.

2. Inspect Suspension Components

Tools Required: Socket set, torque wrench, pry bar
Remove the wheel on the affected side to gain access to the suspension.
Use a pry bar to check for play in the control arms, struts, and bushings.
Replace any worn or damaged bushings, struts, or control arms as necessary.

3. Replace Worn Shocks or Struts

Tools Required: Jack, jack stands, socket set, torque wrench
Lift the vehicle using a jack and secure it with jack stands.
Remove the lower mounting bolts of the shock absorber or strut assembly.
Detach the upper mounting bolts inside the engine bay or trunk.
Replace the shock or strut with a new one, ensuring to use the correct torque specifications for all bolts during reinstallation.

4. Reassemble and Test

Reinstall the wheel and lower the vehicle back to the ground.
Torque the wheel lug nuts to the manufacturer's specifications.
Reconnect the battery and test drive the vehicle over bumps to confirm the noise is resolved.
