Figured out what went wrong last week with it, why it felt nutless, and why the left rear was smoking when I got home.
Looks like somebody didn't get the preload quite right. I must not have gotten all the slack out when I set it up last time. It looks like I can polish the axle until the new bearings will slide on. It seems to have taken on more metal than it lost as the inner race welded itself on. What fun that was to remove. It's completely apart now, gotta clean up the drum and once a bearing slides on/off can reassemble normally (and hopefully correctly this time). I kept thinking the gutlessness was due to the tune I'd just flashed. I changed operating systems and everything, big update, and figured the timing map or something else didn't follow over correctly. That still may be, but this was definitely playing a part.
