Seen a other post online about having pulleys sliding or coming apart and the last one slide and this one the welds broke on the pulley it's self wasn't sure if they may be a reason to why the pulley again the. Next day broke is it maybe to do from the hydroboost or is something shopping flow and the pump locking up wasn't sure if anyone had this issue and kinda had a better idea of why this is happening

Where was the P/S pump from? We have had problems with defective "rebuilt" pumps from the auto parts stores right out of the box, and snapping the shafts.

The pump is a rebuilt from advance had to get a late night pump not many options at 10 pm lol but it broke the pulley right behind the welds of the center point almost like the metal was to weak and bent then broke

So the factory pulley broke, or the P/S pump shaft broke?

The puller did

But with the first one just sliding of the shaft and then bending the pulley and the shaft we replaced the pump and pulley and now the pulley cracked and broke right behind the welds so was seeing if the hydroboost maybe causing it to bend cause of a bad flow

The only time I have seen P/S pump shaft break is because of a faulty unit, or something failed internally in the pump causing a massive pressure spike causing the shaft to break. As said early I have had personal experience with auto parts store re-man pumps snapping shafts and failing out of the box or shortly after install. I would suggest a brand new pump, not a re-man.
