Yep, it was a bearing. Just one, but I had to have it off to tell which one it was. An HHR site had a clear write up on how to change them. Didn't need any special tools. The only hassle was one of the caliper pins was corroded and seized up. That's more because I had to run out and pay retail for the parts.
So, two new bearings and new pins on one brake. The bad pin didn't have the decency to be on the first wheel worked on, but the other side can wait til spring.
For future note, when checking the spin of a drive wheel, should both wheel be off the ground?
Doesn't really matter in the grand scheme if the trans is in neutral. if it's in park, obviously it won't spin at all with only 1 wheel up. on a lift I've tried it in park and in neutral and there's about as much differential noise/vibration either way.
