Solution

1. Preparation

Tools Required: Socket set, torque wrench, jack, jack stands, pry bar, mechanic’s stethoscope
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Inspect Suspension Components

Remove the wheel on the side where the noise is pronounced.
Use a pry bar to check for play in the control arms and bushings.
Replace any worn or damaged bushings or control arms as necessary.

3. Shock Absorber/Strut Inspection

Locate the shock absorbers/struts and inspect for any signs of leakage or physical damage.
If damaged, remove the old shock/strut by:
1. Unbolting the top mount and bottom bolts.
2. Carefully extracting the shock/strut from its mount.
Install the new shock/strut by reversing the removal steps, ensuring all bolts are torqued to manufacturer specifications.

4. Reassemble and Test

Reattach the wheel and lower the vehicle back to the ground.
Reconnect the negative battery terminal.
Perform a test drive to verify that the clunking noise has been resolved.
