The only thing I can really think of is the axle had nothing really maintaining it centered(ie. no needle bearing) and when I hit a bump it got out of balance and started bouncing around until I slowed down enough or it "fixed itself" and got back in balance so that it wasn't hitting anything anymore. I am supporting this theory with the fact that it completely sheared off two of the teeth on my warn hub(the brass component internal to the hub) and the video evidence I posted earlier. Do you guys think I should get an alignment now that all components are replaced?
