Using a multimeter, check the pump’s electrical connections for proper voltage.
If faulty, replace the power steering pump:
- Remove the drive belt from the pump.
- Unbolt the pump from its mounting bracket.
- Install the new pump and reattach the drive belt, ensuring proper tension.

4. Check Steering Rack

Visually inspect the steering rack for leaks or physical damage.
If issues are found, consider replacing the steering rack:
- Raise the vehicle and remove the front wheels.
- Disconnect the tie rod ends from the steering rack.
- Unbolt the steering rack from its mounts and disconnect the hydraulic lines.
- Install the new steering rack and reattach all components in reverse order.

5. Final Assembly

Reconnect the battery.
Refill the power steering fluid reservoir and bleed the system by turning the steering wheel from lock to lock.
Check for leaks around the pump and steering rack.
