Hello and good morning. My 92 240 has a power steering pump thats putting out a loud whine from the pulley. When I spray some lube between the pulley and the box, the sound goes away, so I know its the pulley bearings. The steering box works fine so I was wondering if I could just remove the pulley and replace the bearing. Is this possible? And if so, whats the bearing number? Thanks for any help.
