Thanks, everyone was alright, no one was hurt. I rolled the wheel, brake drum, and axle assembly out of the left lane quick before anyone hit it. Luckily, it rolled kind of off to the edge of the road, up against the plowed-snow bank where it wasn't really in the way. I put some new gear oil in and it seems to be driving great. The wheel bearing looked to be unscratched and felt good so I left that in. I did put a new Timkin axle seal in, the old one got damaged from the axle coming out. Actually, I damaged the first replacement axle seal during installation and had to go back for a second seal. The second try was a charm, and doesn't appear to be leaking.
