Solution

1. Preparation

Gather tools including a socket set, jack stands, and a torque wrench.
Ensure the vehicle is on a flat surface and the parking brake is engaged.
Disconnect the battery to avoid electrical issues during inspection.

2. Inspect and Replace Suspension Components

Inspect Control Arms and Bushings:
- Remove the wheel using a socket set.
- Visually check control arms and bushings for cracks or excessive wear.
- If damaged, proceed to replace with new parts.
Replace Control Arm Bushings:
- Remove bolts securing the control arm to the chassis and suspension.
- Replace old bushings with new ones, ensuring they are properly seated.
- Reinstall the control arm and torque bolts to manufacturer specifications (typically 50-60 ft-lbs).

3. Inspect and Replace CV Joints

Check CV Joints:
- Remove the wheel and inspect the CV joint boots for tears or leaks.
- If the boot is damaged, replace the CV joint, which typically involves:
  - Removing the axle nut and separating the CV joint from the hub.
  - Installing the new CV joint, ensuring the boot is properly clamped.
  - Reinstalling the axle nut and torqueing to manufacturer specifications (usually around 150 ft-lbs).

4. Test Drive and Adjust

Reassemble any removed components and wheels.
Perform a test drive to determine if the clunking noise persists.
If noise remains, further inspection of the steering rack may be necessary.
