Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a level surface.
Disconnect the battery to prevent any electrical issues during repairs.

2. Fluid Inspection and Replacement

Remove the power steering reservoir cap.
Inspect the fluid; if dirty or low, siphon out the old fluid using a turkey baster.
Refill with manufacturer-approved power steering fluid.
Replace the cap securely.

3. Steering Component Inspection and Replacement

Lift the vehicle using a jack and secure it with jack stands.
Inspect the steering rack and tie rods for any play or damage.
If any component is worn, remove the bolts securing the component (use a socket set) and replace with new parts.
Torque bolts to the manufacturer’s specifications (typically around 30-50 Nm, verify with service manual).

4. Power Steering Pump Inspection

Locate the power steering pump and check for leaks.
If a leak is present, remove the pump by disconnecting the hoses and unbolting it from its mount (typically requires a socket set).
Replace with a new pump if necessary. Ensure all connections are tight and secure.

5. Alignment Adjustment

After replacing any components, perform a wheel alignment using a professional alignment machine to ensure proper handling and tire wear.
