I have a 1999 Pontiac Montana. Wife com\complains belt is slipping in the morning making squealing noise goes away after 10-15 mins. So I changed the belt then ran the engine, while checking out the new belt I noticed the belt was vibrating after it came from the harmonic balancer while looking at the balancer it looks like it's shaking out of round this also causes the tensioner to jump am I right to think the harmonic balancer is gone and needs replacement.
