My power steering pump does not line up very well with the rest of the pulleys because the bolt holes dont line up well. It only has 2 bolts in it right now and it kinda lines up with the pulleys but it shakes badly because it doesnt havr the 3rd bolt. The bolt which really does not line up is the far one to the drivers side which mounts to the big bracket that also holds the back of the A/C compressor. Am I missing something? Could I have the wrong PS pump on there? I thought they were all about the same. BTW, my cas has the original LG4 V-Belt setup.

 

That third bolt that threads in from the rear side - isn't that a fun one? You really need to install that one, and may have to loosen the pump and remove the belt to be able to manipulate the pump into position to be able to install this bolt. Once they are all started, you can install the belt and tension it. I'm guessing that it isn't really the foer-and-aft position of the sheave that's the problem as much as the angle of it, right?
