No real change.  I completely leveled the beam, measured across top 
shock mounts, across top of beam, middle of beam, bottom.  Tires are 
off, so I measured again the range of ball joint movement with the beam 
100% level.  I'm getting about 2.9-3.7 on the right side, and 2.0-2.5ish 
on the left.  It might have hit 1.9-2.6, but the sun was making the 
level hard to read.  This makes sense with last nights numbers, because 
when I measured the beam before leveling it, it was about 0.2 degrees.

I then switched ball joints from side to side.  No change, the right 
side is still about 1.5 degrees more than the left.  Setting both sides 
as low as they'll go, I can visually tell that the right side has too 
much positive camber.  (Note: I said left wheel last night but that was 
looking from the front, the passenger/right side has too much camber).

As for the bearing damage with the original beam it was on the 
left/driver side, opposite of my problem wheel.
