Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and the engine is off.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect Suspension and Steering Components

Tools Required: Socket set, torque wrench, pry bar.
Remove the front wheels to access the suspension and steering components.
Inspect the control arms, bushings, and ball joints for wear. Replace any worn components.
Check the tie rod ends and steering rack for any looseness.

3. Check CV Joints

Tools Required: CV joint puller (if necessary).
Inspect the CV boots for tears or leaks. If damaged, replace the CV joint or boot.
Rotate the wheel and listen for any clicking or clunking noises which indicate a failing CV joint.

4. Inspect Wheel Bearings

Tools Required: Torque wrench, wheel bearing puller (if necessary).
With the vehicle raised, grab the wheel at the 12 and 6 o'clock positions and check for play. If there is movement, the wheel bearing may be worn and should be replaced.
Follow manufacturer specifications for bearing torque values during reassembly.

5. Reassemble and Test

Reinstall the wheels and lower the vehicle to the ground.
Torque the lug nuts to the manufacturer's specifications.
Reconnect the battery and perform a test drive to ensure the noise has been resolved.
