Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Power Steering Fluid

Remove the power steering fluid reservoir cap.
Check the fluid level against the minimum and maximum marks.
If low, top off with manufacturer-recommended power steering fluid.
If fluid is dirty or contaminated, perform a complete fluid flush:
- Disconnect the return line from the pump and place it in a container.
- Start the engine briefly to pump out old fluid (do not run dry).
- Reconnect the line and refill the reservoir with fresh fluid.

3. Inspect and Replace Power Steering Pump (if faulty)

Remove any components obstructing access to the power steering pump.
Disconnect the power steering hoses from the pump using appropriate wrenches.
Unbolt the pump from its mounting bracket.
Install the new power steering pump:
- Align it properly and secure with bolts to the manufacturer's torque specifications.
- Reconnect the hoses, ensuring they are tight and leak-free.

4. Inspect Steering Rack and Tie Rods

Lift the vehicle using a jack and secure it on jack stands.
Inspect the steering rack and tie rods for wear or damage.
If any components are worn, replace them:
- Remove the tie rod ends using a tie rod puller.
- Replace with new parts and ensure proper alignment.

5. Final Assembly and Fluid Check

Reassemble any components that were removed during the process.
Start the engine and turn the steering wheel from lock to lock several times to bleed air from the system.
Check power steering fluid level again and top off if necessary.
