bad crank pulley?

[0r1landoDSM]

i just put in my alternator and the alternator belt on the crank pulley keeps mis aligning.. when i watch the pulley as the car is on i see it wobbling a tiny bit not moving straight fluently. would the mis aligning be b.c of the of alternator? or bad crank pulley? oh and it also makes small squeeking noises

i put my hand on the belt and it feels tensioned(tight) no play in the belt

make sure the crank pulley bolts are properly tightened, then watch your pulley while the car is running. it shouldnt wobble any. a common sign of a dead crank pulley is the rubber insulator is cracked/missing/damaged and that it throws your access belts.
