Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery negative terminal for safety.

2. Inspect and Replace CV Joints (if damaged)

Lift Vehicle
- Use a jack to lift the front of the vehicle and support with jack stands.
- Tools Required: Jack, jack stands, wheel chocks.
Remove Wheel
- Loosen lug nuts and remove the front wheel.
- Tools Required: Lug wrench.
Inspect CV Joint
- Check the CV joint and boot for tears or excessive wear.
- If damaged, proceed to replace the CV joint.
Remove CV Axle
- Remove the axle nut using a socket and ratchet.
- Disconnect the lower control arm if necessary to free the CV axle.
- Pull out the CV axle from the transmission and hub.
Install New CV Joint
- Coat the new CV joint with grease as per the manufacturer’s specifications.
- Insert the new CV axle into the hub and transmission.
- Reattach the axle nut and torque it to the manufacturer's specification (usually around 30-50 ft-lbs).

3. Inspect and Replace Wheel Bearings (if faulty)

Remove Brake Caliper
- Detach the brake caliper from the rotor.
- Tools Required: Socket set, caliper hanger.
Remove Brake Rotor
- Slide off the rotor from the hub assembly.
- Tools Required: Hammer (if stuck).
Check Wheel Bearing
- Rotate the wheel hub to check for roughness or grinding.
- If faulty, remove the wheel bearing.
Replace Wheel Bearing
- Use a bearing puller to extract the old bearing.
- Install the new bearing using a press or hammer (ensure it’s properly seated).
- Reassemble the rotor and caliper in reverse order.

4. Reassemble and Test

Reattach the wheel and lug nuts.
Lower the vehicle from the jack stands.
Reconnect the battery terminal.
Test drive the vehicle to ensure the noise is resolved.
