Dan-
You know it's a bearing/fork problem because it goes away once you engage them slightly.
It could be a wrong fork or a wrong sized release bearing that would tend to 'cock' the bearing.
But my first thought is that this style of external slave demands a stiff return spring to keep the release bearing off the clutch forks.
This also helps keep the 'self adjusting' feature of this setup functional.
Basically you should have at least 1/16" over all clearance between the release (throw out) bearing around the circumference of the clutch's arms.
The heavy spring holds the fork off the clutch arms to prevent the bearing from 'racing' with out load (source of whine?) all the time.
The spring should be in line with the trannie shaft center line, the fork's pivot, and the slave's rod ...
Good luck.
It should take longer than a weekend to totally crap out a new release bearing.
But just in case, I'd toss in a tool box and an extra one and go have fun ...
