Death Wobble After Ball Joint Swap

[blown240]

I put a new upper ball joint on my panel this weekend. I also removed a couple of the camber shims to get the wheel to not lean out, and took out a 1" wheel spacer.

I drove it today for the first time since the work, and at 40-45 mph it gets a bad wobble. It had a wobble when I first bought it, but new tires got rid if it.

What can cause this?
1. Ball joint isn't tight.... I tightened it with the front off the ground and the suspension hanging.
2. Tire is worn odd, and causing this
3. Tire toe is bad is toe out
4. $$$

under 40 mph i barely feel the wobble, but at 45 it gets bad.

Thoughts? Ideas?
