Gary, thnaks so much for your post regarding replaceing the power steering pump on a 2003 workhorse. I am now faced with a leaking pump and I am paying a local shop to repair (replace the pump) those pumps are not standard and cost $595 from Ultra RV who also owns the workhorse parts web site. The shop has decided to cut out the wheel liner to access the pump.
thx again, jim bennett (jmbennett07@yahoo.com) (805) 459-1132
