Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, OBD-II scanner.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Inspect and Replace Wheel Bearings (if needed)

Lift Vehicle: Use a jack to lift the vehicle and secure it with jack stands.
Remove Wheel: Take off the wheel where noise is suspected using a socket set.
Inspect Bearing: Spin the hub and listen for grinding or roughness.
Remove Old Bearing: If defective, remove the hub and bearing assembly.
Install New Bearing: Place the new bearing in the hub and secure it using the appropriate torque specifications (check manufacturer specs).
Reassemble Wheel: Reattach the wheel and lower the vehicle.

3. Check Driveshaft and CV Joints

Visual Inspection: Check for any visible cracks or tears in the CV boots.
Remove Driveshaft (if necessary): If damage is found, remove the driveshaft and inspect the joints.
Replace Joints: If worn, replace the CV joints with new ones, ensuring they are properly greased.
Reinstall Driveshaft: Secure the driveshaft back in place and torque to specifications.

4. Inspect Suspension Components

Visual Inspection: Look for worn struts, bushings, or any loose components.
Replace Worn Components: If any parts are damaged, replace them as necessary.
Reassemble: Ensure everything is tightened to manufacturer specifications.
