some cars in my case there is a lot of vibration when hubs moves, but after some speed everything is good, some other cars, any vibration. that's normal since hub dyno absorbs vibrations that tires do. also it has to do too with some cars with very very stiff suspension.

if you have axial vibration, it has to do with balance of your shafts. if you have any video maybe i can try to help you a bit more. what do you use for absorb vibration/ adjust camber?
