Inspect the power steering pump for any signs of damage or wear.
Check all hoses for cracks or leaks; replace as necessary.
If the pump is faulty, remove it by unbolting it from its mounting and disconnecting the hoses.
Install a new pump by reversing the removal process; ensure all connections are secure.
