My power steering pump was whining pretty loud and it felt like it was getting weak so I upgraded it with a pump from a WJ with a hydraulic fan clutch.
When I did the upgrade I was surprised at the lack of difference I felt. A year or so prior to replacing the power steering pump, I upgraded to a faster s-10 power steering box. For a while it was fine but now my steering feels all kinds of sloppy. I attributed it to being used to driving my new Lincoln LS, but now I'm thinking it's abnormally sloppy, especially considering the "upgraded" power steering box.
But what baffles me is why my "new" power steering pump is whining. I realize that it was a junkyard upgrade and there's definitely the possibility of getting a bad pump but the junkyard verified that it was in working order and the WJ that it came from only had ~70k miles. Besides that, when I first did the swap, the power steering pump was quiet but now it's whining similar to (but not quite as loud as) the old pump.
Therefore I'm thinking the problem must somehow lie in the box and that somehow it's making the pump whine. But I don't know all that much about power steering boxes so any help would be greatly appreciated.
