Default Balancing a fan

I got so much help on my sprayer, I'm trying again...

Full time investigation and part replacement has me working on this theory
of the problem cause: The squirrel cage fan is out of balance. It is barely
detectable because the fan has a 2" solid steel shaft and some serious
pillow block bearings mounted solid to a beefy frame. At the resonate RPM,
this imbalance feeds on the slack in the drive line. Any system upset causes
the fan to become unstable and it lurches back and forth.

I've called around and not found a place to dynamic balance something like
this. Are there any home brew methods? Or other suggestions? Its built so
solid I don't think I'm looking for a minor imbalance.
