Travelling from Nevada to Alaska in the Middle of Winter

So I finally finished the repack and I hope and pray I did it right. A couple of concerns I had when working this. Three of the four hubs were difficult to remove and reinstall because the brake pads were quite snug to the drum. Also, the wheel that had some very slight movement seems to be a bit better but when I spin the wheel it starts smooth but then kind of rattle to a stop. It almost seems to be a balance issue.
