Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the negative battery terminal to avoid electrical issues.

2. Check 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, add the manufacturer-recommended power steering fluid until the correct level is reached.
4. Inspect the fluid quality; if it's dark or contaminated, it may need to be flushed.

3. Inspect Power Steering Pump

Sub-steps:
1. Visually inspect the power steering pump for leaks or damage.
2. Check the drive belt for fraying or signs of wear—replace if necessary.
3. Start the engine and listen for unusual noises from the pump; replace the pump if it is noisy or not functioning correctly.

4. Check Steering Rack

Sub-steps:
1. Raise the front of the vehicle using jack stands.
2. Inspect the steering rack for any fluid leaks or physical damage.
3. Check the rack's operation by moving the steering wheel back and forth to see if it binds or feels rough; replace if defective.

5. Test Serpentine Belt

Sub-steps:
1. Inspect the serpentine belt for wear, cracks, or glazing.
2. Replace the belt if it shows signs of damage.
3. Ensure proper tension on the belt; adjust or replace the tensioner if necessary.
