Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery if necessary for safety.

2. Tire Inspection

Sub-steps:
- Inspect each tire for uneven wear or foreign objects embedded in the tread.
- Check tire pressure and inflate as needed.
Tools Required: Tire pressure gauge, jack, jack stands.
Safety Warnings: Ensure the vehicle is securely lifted before working underneath it.

3. Wheel Bearing Inspection

Sub-steps:
- Lift the front and rear of the vehicle with a jack.
- Spin each wheel by hand and listen for grinding or roughness.
- If noise is detected, remove the wheel and inspect the bearing for wear.
Tools Required: Socket set, torque wrench.
Safety Warnings: Use jack stands to support the vehicle securely.

4. Drive Belt Inspection

Sub-steps:
- Locate the drive belts in the engine bay.
- Check for fraying, cracks, or signs of misalignment.
- Replace any damaged belts with OEM or high-quality aftermarket parts.
