Solution

1. Preparation

Tools Required: Socket set, torque wrench, OBD-II scanner, fluid catch pan.
Ensure the vehicle is on a flat surface and the engine is off.
Disconnect the battery to avoid any electrical issues.

2. Inspect Power Steering Fluid

Remove the power steering fluid reservoir cap.
Check fluid level against the markings; add fluid if low (use manufacturer-recommended fluid).
Inspect fluid for contamination or burnt smell; replace if necessary.

3. Check for Leaks

Visually inspect all power steering hoses and connections for signs of leaks.
Clean any spilled fluid and monitor for fresh leaks while the engine is running.
If leaks are found, replace the affected hoses or fittings.

4. Test Power Steering Pump

Start the engine and turn the steering wheel from lock to lock.
Listen for unusual noises; if the pump is noisy, it may need replacement.
Measure the power steering pressure using a gauge while turning the wheel. Refer to the service manual for specifications.

5. Inspect Steering Components

Raise the front of the vehicle and secure it on jack stands.
Inspect the steering rack and tie rods for any wear or damage; replace components as necessary.
Check for play in the steering linkage by moving the steering wheel back and forth while observing the linkage.

6. Final Assembly and Testing

Reinstall any components that were removed during the inspection.
Reconnect the battery.
Test drive the vehicle to ensure the steering issue has been resolved.
