Hey guys, first time posting on here and yes, I've searched for my answer. I need to know the exact length of the rear axle bearing spacer tube so I can make one. I'm a fabber by trade. I had a wheel bearing blow out on me a few days ago, got some SKF 6006 2RS1/C3 bearings from work (brand new in box) threw them on the bike and less 30 miles I can hear a light clicking noise from the rear end. So, pulled it all apart and I noticed then that the spacer just kinda rolls around in the wheel. I know its suppose to be tight. One end of it is very slightly mushroomed. Any help guys?
