Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine turned off.

2. Tire Inspection

Sub-steps:
1. Check tire pressure using a tire pressure gauge and inflate to the manufacturer's recommendation.
2. Visually inspect tires for signs of uneven wear or damage.
3. Rotate tires if wear is uneven to ensure even tire life.
Tools Required: Tire pressure gauge, tire iron.

3. Wheel Bearing Inspection

Sub-steps:
1. Raise the front or rear of the vehicle using a jack and secure with jack stands.
2. Grab the wheel at the 12 and 6 o'clock positions and wiggle. There should be minimal play.
3. Spin the wheel and listen for any grinding or roughness, which indicates a failing bearing.
Tools Required: Jack, jack stands.

4. Drivetrain Components Check

Sub-steps:
1. Inspect the driveshaft for any visible damage or excessive play.
