- Remove the serpentine belt by releasing the tensioner with a wrench.
- Inspect the belt for cracks or fraying; replace if damaged.
- Reinstall a new belt, ensuring it’s correctly routed and tensioned.

4. Examine Drivetrain Components

Sub-steps:
- Raise the vehicle using a jack and secure it with jack stands.
- Inspect the driveshaft for play or damage; replace if necessary.
- Check the differential fluid level; if low, top up with the manufacturer's recommended fluid.
