Solution

1. Preparation

Tools Required: Jack stands, lug wrench, OBD-II scanner, socket set, torque wrench.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery for safety if working on electrical components.

2. Tire Inspection

Remove the wheel covers or hubcaps if applicable.
Use a lug wrench to loosen and then remove the lug nuts completely.
Inspect each tire for signs of uneven wear or foreign objects lodged in the tread.
Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications.

3. Wheel Bearing Inspection

Lift the vehicle using a jack and secure it with jack stands.
Spin the wheel by hand and listen for grinding or roughness, indicating a bad bearing.
If noise is present, use a socket set to remove the wheel and access the wheel bearings.
Replace any faulty wheel bearings, ensuring proper lubrication.

4. Drivetrain Inspection

Inspect the driveshaft and CV joints for any visible damage or excessive play.
If the driveshaft or joints are damaged, remove them using a socket set and replace with new parts.
Ensure all connections are secure and properly torqued.

5. Reassembly and Final Checks

Reinstall all removed components in reverse order.
Reconnect the battery and clear any error codes with the OBD-II scanner.
Lower the vehicle back to the ground and perform a final torque check on the lug nuts.
