Solution

1. Preparation

Gather tools: socket set, wrench set, OBD-II scanner, fluid catch pan.
Ensure the vehicle is on a level surface and the engine is cool.
Disconnect the battery for safety.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
1. Remove the power steering fluid reservoir cap.
2. Check fluid level; if low, add the manufacturer-recommended fluid.
3. If the fluid is dirty or has metal shavings, prepare to flush the system.
4. Using a fluid catch pan, drain the old fluid from the reservoir.
5. Refill with new power steering fluid and replace the cap.

3. Inspect and Replace Power Steering Pump (if needed)

Sub-steps:
1. Remove the serpentine belt by loosening the tensioner pulley with a wrench.
2. Disconnect the power steering pump from the hoses (use a line wrench to avoid damage).
3. Unbolt the power steering pump from its bracket and remove it.
4. Install the new power steering pump by reversing the removal steps, tightening bolts to manufacturer specifications.
5. Reconnect the hoses and serpentine belt.

4. Bleed the Power Steering System

Sub-steps:
1. With the engine off, turn the steering wheel fully left and right several times to remove air from the system.
2. Start the engine and repeat the steering motion to fully bleed the system.
3. Check fluid level and top off as necessary.
