Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Wear safety glasses and gloves.

2. Inspect Power Steering System

Tools Required: Screwdriver, funnel, power steering fluid.
Check the power steering fluid level using the dipstick.
If low, fill with the appropriate power steering fluid until it reaches the correct level.
Inspect power steering hoses for leaks or damage.

3. Check Transmission Fluid

Tools Required: Transmission fluid dipstick, funnel.
Remove the transmission fluid dipstick and check the fluid level.
If low, add the recommended transmission fluid until it reaches the proper level.
Check the fluid condition; if burnt or dirty, consider a fluid change.

4. Inspect Serpentine Belt

Tools Required: Belt tension gauge, flashlight.
Visually inspect the serpentine belt for signs of wear or damage.
Check the tension; if loose, adjust or replace the tensioner if necessary.

5. Examine Wheel Bearings

Tools Required: Jack, jack stands, wheel chocks, torque wrench.
Lift the vehicle and remove the wheel.
Grasp the wheel at 12 and 6 o'clock and check for play; any movement indicates worn bearings.
If necessary, replace the wheel bearings following manufacturer specifications.
