Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, fluid catch pan, jack and jack stands, torque wrench.
Park the vehicle on a flat, stable surface and engage the parking brake.
Allow the engine to cool if it has been running.

2. Inspect and Replace Serpentine Belt

Sub-steps:
1. Remove the engine cover (if applicable) by unscrewing the bolts.
2. Use a socket wrench to loosen the tensioner pulley and remove the serpentine belt.
3. Inspect the belt for cracks, fraying, or glazing. Replace if necessary.
4. Install the new serpentine belt by routing it according to the belt diagram usually located on the engine cover.
5. Tighten the tensioner pulley and ensure proper belt tension.

3. Check Power Steering System

Sub-steps:
1. Locate the power steering fluid reservoir and check the fluid level; add fluid if low.
2. Inspect hoses for leaks or damage and replace any faulty components.
3. If fluid is contaminated, flush the power steering system and refill with manufacturer-recommended fluid.

4. Inspect Transmission Fluid

Sub-steps:
1. Remove the transmission dipstick and check the fluid level and condition.
2. If fluid is low, top it off with the appropriate transmission fluid.
3. If the fluid is burnt or contaminated, perform a transmission fluid change.

5. Wheel Bearing Inspection

Sub-steps:
1. Safely lift the vehicle using a jack and secure it with jack stands.
2. Grab each wheel and check for play; any movement indicates a bad wheel bearing.
3. If bearings are defective, remove the wheel and hub assembly to replace the bearings.
