Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent electrical mishaps.

2. Inspect Power Steering Fluid

Sub-steps:
1. Locate the power steering fluid reservoir.
2. Remove the cap and check the fluid level. If low, top off with recommended power steering fluid.
3. Inspect fluid quality; if dark or contaminated, it will need to be replaced.
Tools Required: None specific for this step.

3. Check for Leaks

Sub-steps:
1. Visually inspect all power steering hoses and connections for signs of leaks.
2. If leaks are found, replace the damaged hoses or connections.
3. Clean any fluid residue and retest the system for leaks.
Tools Required: Torch light for inspection.

4. Inspect Serpentine Belt

Sub-steps:
1. Examine the serpentine belt for cracks, fraying, or signs of wear.
2. Check the tensioner for proper tension; replace if it's loose or faulty.
3. If the belt is damaged, replace it with a new one.
Tools Required: Socket set, belt tensioner tool.

5. Wheel Bearing Inspection

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Rotate each wheel by hand to listen for noise or roughness.
3. If noise is present, remove the wheel and inspect the bearings for wear.
4. Replace any worn or damaged wheel bearings.
Tools Required: Jack, jack stands, socket set.

6. Steering Pump Check

Sub-steps:
1. Start the engine and listen to the steering pump for any abnormal noise.
2. If noise persists, check the pump's mounting and connections.
3. If necessary, replace the power steering pump.
Tools Required: Socket set, possibly a pulley puller.
