Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and turn off the engine.
Disconnect the battery to avoid electrical issues.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; top off with the appropriate fluid type if low.
Inspect the fluid condition; if it appears dark or contaminated, it may need to be replaced.

Visually inspect all hoses and connections for any signs of leaks.
Clean any areas with fluid residue and monitor for reoccurrence after the vehicle has been run.

4. Test the Power Steering Pump

Examine the power steering pump for any unusual noises or signs of wear.
If necessary, remove the pump by loosening the mounting bolts and disconnecting the inlet and outlet hoses.
Replace the pump if it is found to be defective.

5. Examine the Steering Rack

Check the steering rack for binding or damage.
If there is resistance, it may require lubrication or replacement.

6. Inspect the Serpentine Belt

Check the tension and condition of the serpentine belt.
Replace the belt if it shows signs of wear or does not maintain proper tension.
