Solution

1. Preparation

Gather tools: Tire pressure gauge, jack and jack stands, socket set, and torque wrench.
Ensure vehicle is on a flat surface and secure with wheel chocks.
Disconnect the battery if working on electrical components.

2. Tire Inspection

Remove the wheel covers or hubcaps if applicable.
Inspect each tire for uneven wear and proper inflation (recommended PSI is typically found in the driver’s door jamb).
If uneven wear is found, rotate or replace tires as necessary.

3. Wheel Bearing Inspection

Raise the vehicle using a jack and secure it with jack stands.
Grab the wheel at the 12 and 6 o'clock positions and shake it gently.
If there is movement, the wheel bearing is likely worn and should be replaced.

4. Drivetrain Component Check

Inspect the CV joints and boots for any signs of wear or damage.
Check the differential fluid level and condition; if low or dirty, replace it.
Examine the driveshaft for any signs of wear or imbalance.

5. Reassembly

Reinstall wheels and torque the lug nuts to manufacturer specifications.
Lower the vehicle from the jack stands.
Reconnect the battery if it was disconnected.
