Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery (if necessary for electrical components).

2. Inspect and Refill Power Steering Fluid

Sub-steps:
1. Locate the power steering fluid reservoir.
2. Remove the cap and check the fluid level; it should be between the "MIN" and "MAX" marks.
3. If low, top off with manufacturer-recommended power steering fluid.
4. Check the condition of the fluid; it should be clear and not burnt or contaminated.

3. Check for Leaks

Sub-steps:
1. Inspect power steering hoses and connections for signs of leaks (damp spots, wetness).
2. Examine the steering rack for leakage.
3. If leaks are found, replace the damaged hoses or rack as necessary.

4. Replace Power Steering Pump (if noisy or ineffective)

Sub-steps:
1. Disconnect the battery.
2. Remove any components obstructing access to the power steering pump.
3. Disconnect the hoses from the pump; be prepared for fluid spillage.
4. Unbolt the pump from its mounting bracket.
5. Install the new power steering pump and reconnect the hoses.
6. Refill the power steering fluid and bleed the system as per manufacturer instructions.

5. Inspect Steering Components

Sub-steps:
1. Check the steering linkage for wear (tie rods, ball joints).
2. Replace any worn components.
3. If necessary, perform a wheel alignment after component replacement.
