Solution

1. Preparation

Tools Required: Jack and jack stands, OBD-II scanner, flashlight, safety goggles, gloves.
Safety Warnings: Ensure the vehicle is on a flat surface and secure with jack stands before working underneath.

2. Inspect and Replace Drive Belts

Sub-steps:
1. Loosen the tensioner pulley using a socket set and remove the old belt.
2. Inspect pulleys for wear or damage, ensuring they rotate freely.
3. Install a new serpentine belt, ensuring it is routed according to the belt diagram usually found on the engine cover.
4. Tighten the tensioner pulley to the manufacturer's specifications (check the service manual for specific torque values).

3. Address Power Steering Issues

Sub-steps:
1. If low, add the recommended type of power steering fluid (check the owner's manual).
2. Inspect the power steering pump for leaks; if leaking, replace the pump.
3. If the pump is noisy but not leaking, replacement may be necessary.

4. Inspect and Replace Wheel Bearings

Sub-steps:
1. Remove the wheel and tire from the affected side.
2. Remove the brake caliper and rotor to access the wheel hub.
3. Inspect the wheel bearing for play or noise; if faulty, replace the bearing.
4. Reassemble components in reverse order, ensuring all bolts are tightened to specifications.
