The hubs on my 12 are loose on the spline of the axle. This lets the wheel rock back and forth while attached. Has anyone ever came up with a fix to cure this problem apart from putting on different hubs? I was thinking of taking the hubs off and drilling and tapping a hole on the inside of the hub into the splines and then grinding a small flat spot on the axle and putting a setscrew in the threaded hole and running it down to lock the hub on like a set collar. Anyone see a downside to the idea or have a different suggestion apart from changing the hubs?
