- Locate the power steering fluid reservoir.
- Remove the cap and check the fluid level; add fluid if low.
- Inspect the fluid for contamination; if dirty, it may need to be flushed.
Tools Required: None
Safety Warnings: Always wear gloves when handling fluids.

3. Inspect Power Steering Pump

Sub-steps:
- Visually inspect the power steering pump for leaks or physical damage.
- Check the drive belt for proper tension and condition.
- If leaking, replace the pump.
Tools Required: Socket set, belt tension gauge
Safety Warnings: Ensure the engine is turned off and cool before inspection.

4. Check Steering Linkage

Sub-steps:
- Raise the front of the vehicle using jack stands.
- Inspect the steering rack and tie rod ends for wear or damage.
- Replace any worn components as necessary.
Tools Required: Socket set, wrenches
Safety Warnings: Always support the vehicle securely with jack stands.

5. Test Power Steering System Pressure

Sub-steps:
- Connect a power steering pressure gauge to the pressure port on the steering pump.
- Start the engine and observe the pressure readings; they should be within manufacturer specifications.
- If pressure is low, it may indicate a failing pump or blockage in the system.
Tools Required: Power steering pressure gauge
Safety Warnings: Be cautious of moving parts while the engine is running.
