Solution

1. Preparation

Tools Required:
- Socket set
- Torque wrench
- OBD-II scanner
- Fluid catch pan
- Funnel
Park the vehicle on a level surface, engage the parking brake, and allow the engine to cool before starting work.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir (usually near the engine).
Remove the cap and check the fluid level against the dipstick.
If low, add the recommended power steering fluid type (usually Dexron III or equivalent).
Inspect the fluid for contamination (dark color or debris).

3. Inspect for Leaks

Visually inspect the power steering pump, hoses, and connections for any signs of fluid leaks.
If leaks are found, replace damaged hoses or seals as necessary.

4. Test Power Steering Pump

Start the engine and turn the steering wheel from lock to lock several times.
Listen for any unusual sounds (whining or grinding) indicating a failing pump.
If noises persist, consider replacing the power steering pump.

5. Check Power Steering Belt

Inspect the power steering belt for signs of wear, fraying, or cracking.
If damaged, loosen the belt tensioner and replace the belt.
Re-tighten the belt to the manufacturer's specified torque.
