1997 SH... I have the "monsterous" AEM pullies on here btw. (Anyone know where to get the replacement belts for these pullies?)

I replaced my power steering pump and now the power steering belt is halfway off the pulley. What could be causing this? misalignment?

I was trying to look if I missed any bolts or washers and I know I got everything on correctly.

Anyone have any ideas I would greatly appreciate it. I dont want it to fall off when im driving. :/

Thanks
