It doesn't make the noise if the belt is off. Belt tensioner and water pump have been replaced.
I need to supercharge this thing or buy another van...
Is my harmonic balancer going bad?

Re: Is my harmonic balancer going bad?
One test I do know of to check the harmonic is to see if there is any play in it. Try to move the belt with the engine off...there should be none.
Sounds like a bad tensioner/idler pulley to me though. Thats the sound they make when the bearings go bad. I've had one go bad on almost every car I've maintained. 93's went bad at 97k.
With the belt off...see how easy the tensioner pulley turns...should feel semi-tight, not loose and spins like nothing.

Sounds a lot like the Dampener is gone...
How far can you rotate the belt? If you have any back and forth plat at all the Dampener is shot

Re: Is my harmonic balancer going bad?
Can I drive it like this for a day or two until I can get it fixed? *dang* thing won't come off with 3 different pullers and I'm going to end up having to pay someone to take it off.

Re: Is my harmonic balancer going bad?
I wouldn't totally recommend it.... But your doesn't sound horrible yet..
Whats happening is that the balancer is hitting the stops, the outer part of the balancer has the rubber in the middle, this rubber is the dampener... The center of the dampener( metal part ) actually moves on a roller bearing, so this allows for rotational play in the pulley absorbing or dampening items like the compressor clutch turning on and or off..
When the rubber breaks the dampener can bounce off the stops creating a horrible racket...
