Ok update I just talked to someone that knows a bit about this stuff and he thinks the bearings are bad that the pully mounts too. So he sugests if you never did replace the whole asembly (bearings) not just the pully to do so. He also thinks it could be the tensioner pulley but to start with the bearings to the one that broke before.

So is the car sill broken or giving you problems?

You might want to see if you can get a metal ribbed tensioner pulley. I've had problems with plastic ones, switched to metal and never had a problem since.
