knocking noise from ac compressor pully

[ultravorx]

Well, today after detailing my marauder, i noticed a knocking noice coming from the engine. after a little digging, i saw its coming from the ac compressor.
Whats weird about it everytime it knocks, the belt jumps a little bit around the ac compressor. The belt is properly lined up, and it is a brand new gator back belt. i remove the belt and there are no strange wear mark on the belt or the compressor pully, nor is the pully loose suggesting bad bearings. any ideas on a fix for this? im at a loss right now.

Check the tensioner, I already went through one at 26k miles and it seems to be a common problem. Plus its only $30 so its worth the shot.
Other then that it sounds like weak clutches in the compressor that slip under strain

Frank, does this happen only when the AC is engaged, or all the time?

The magnetic hub on the compressor is engaging. Have a nice day and stop worrying now.

it only happens after the ac is engaged, about 2-3 seconds after it engages it starts "clunking" when it disengages, the noice stops.
