Ok, I took the hub off of the other side of this axle without issue, replaced it, and I think everything is on right in the proper order. I get to this side and There is something jammed on the axle. I'm assuming it's not supposed to be there because I can't get the new hub on far enough... Is it supposed to come off? I am 99 percent sure there wasn't one on the other side because the hub slid right on... It almost looks like a piece that had bearings on it at some point... Thanks for the insight. Craigan.
