Misaligned Belt '07 JK 3.8L

My power steering pump went out a few weeks ago and I got it replaced at a local mechanic shop that I have never been to. I specifically mentioned that I did not want a refurbished pump. Well I only drove four blocks before turning around and taking it back. They put in a new pump and after a couple of days I developed a squeak that changed pitch with the RPMs. I took it to my hometown mechanic and he just replaced the belt tensioner, belt and placed a washer behind the upper idler pulley to help the belt align better. Well now there is a very loud ticking noise coming from the power steering pump pulley and the belt is wobbling horribly. I removed the washer and it did not help. I figured out that the noise is coming from the ribs of the belt and power steering pump pulley rubbing against each other because the belt is misaligning on the pulley itself and snapping back into place at the top of the pulley. I do not want to take it back to the same mechanic if they can not even install a power steering pump correctly. Should I just reinstall the pump and pulley myself? Does anyone have the torque specs for the power steering pump and pulley? Is something else causing this misalignment? I can upload pictures and videos if needed. Trying to fix it quickly as my jeep is an everyday driver and I do not want to shred through serpentine belts!

The pulley on the pump is supposed to be aligned by the shop when they install it, at least thats the way it worked with my TJ when I had to replace the pump. I believe there is a specific pulley puller for power steering pumps.

There is a puller, I am just reluctant to take it back to the same shop after they have struggled twice to replace it. I am hoping someone can give me some advice on how to realign it on my own.

Their is a laser alignment tool that you can use. Google dayco pulley alignment tool.

Aligning the belt? Lasers?

WTF

Granted it has been a long time, but I used to pull power steering pulleys off and press them into the replacement pump all the time. You must use a power steering pump pulley puller or else the pulley becomes damaged which is probably what happened in this case. The idea of using a washer to space out the tensioner is assanine.

You press the pulley into the replacement pump until the lip of the pulley is flush with the end of the shaft. It is really simple. And there is nothing wrong with a remanufactured pump from a reputable company such as acardone commonly called A1. They come with a lifetime warranty.

Every person that has worked on your Jeep is an idiot.
