AC belt keeps popping off

[bigbengalbubba]

2003 1500hd with a broken AC belt. During belt replacement I noticed that the tensioner pulley would not turn. I removed it and saw that it was cockeyed and jammed on the bracket. I took it off and a ball bearing fell out. I put it back together and it turned ok although not perfectly smooth. Now the belt keeps popping off within seconds of starting the truck.

I watched to see what was happening and all I can see is that the tensioner moves to where the belt is loose and it pops off. Would my next move be replacing the tensioner?
