Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and is secure.
Disconnect the battery before working on electrical components.

2. Inspect Power Steering System

Sub-steps:
- Locate the power steering reservoir and check fluid level.
- If low, top up with manufacturer-recommended power steering fluid.
- Inspect hoses for leaks or damage; replace if necessary.

3. Inspect and Replace Belts

Sub-steps:
- Visually inspect serpentine and accessory belts for wear or fraying.
- If damaged, use a socket set to remove the tensioner and replace the belt.
- Ensure proper alignment and tension of the new belt (check manufacturer's specifications).

4. Inspect Wheel Bearings

Sub-steps:
- Jack up the vehicle and secure it with jack stands.
- Spin each wheel by hand and listen for any grinding or roughness.
- If noise is detected, remove the wheel and inspect the bearing; replace if necessary.

5. Check Differential Fluid

Sub-steps:
- Locate the differential and check fluid level using the fill plug.
- If fluid is low or dirty, drain and refill with manufacturer-recommended gear oil.
- Inspect for leaks around seals and gaskets.
