Solution

1. Preparation

Tools Required: Wrench set, OBD-II scanner, fluid catch pan, safety gloves.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid electrical shorts.

2. Inspect Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; top off with the recommended fluid if low.
Inspect fluid for contamination; if dirty, it may need to be flushed.

3. Check for Leaks

Use a flashlight to inspect hoses and connections for signs of leakage.
If leaks are found, replace damaged hoses or seals as necessary.
Clean any spilled fluid to prevent slipping hazards.

4. Inspect Power Steering Pump and Belt

Locate the power steering pump; check for signs of wear or damage.
Inspect the drive belt for cracks or fraying; replace if necessary.
If the pump is noisy or not producing pressure, it may require replacement.

5. Check Steering Rack and Components

Visually inspect the steering rack for any visible damage or leaks.
Verify that all steering linkage components are secure and free of play.
If any components are worn, replace them according to manufacturer specifications.

6. Reconnect and Test

Reconnect the battery and start the engine.
Turn the steering wheel from lock to lock to bleed air from the system.
Check for proper operation and fluid level again, topping off as needed.
