Our Club and another sponsored a rally this weekend and I finally got to race the Blaze. It was a double elimination 300 foot track. I placed first and even made the local paper. Of course the cK5 stickers were even visible, Got to love the advertisment. But now the bad news. I was talked into doing the mud drag the next day (Swore i would never hit the mud cause that's what makes trucks break. Well I did!!!! Thank God i only gernanded a front hub. Well tonight I tried changing it and spent over an hour trying to get it out. I ended up fabbing a hub puller to get it out. Well my question is how much up and down movement should be in a 10 bolt short shaft? i have at least 1/4-3/8" of play up and down. P.S. The new MT/R's kicked ass1!!!!
