Integy arbors for 12th scale have a known issue about them.
They are nearly impossible to balance. They will always wobble, the part that locks into the wheel is not hollow the like the Hudy one. Thus it puts the weight at the end and causes it to wobble.
Trust me I have both Integy arbors for 12th and 10th touring.
The tenth touring is a pain also, cause it has a set screw to lock on the arbor which can cause it to not be centered on the shaft and cause it to wobble. The Hudy’s crimp on the output shaft of the motor, not like the Integy one.
Once I purchased the Hudy 12th scale arbor I never used the Integy one again. I had a friend drill out the cone that tightens down on the wheel and the problem went away.
Every now and then rear wheels for 12th scale can be a pain to tighten and balance at the same time. So, I am using the Integy arbor as a donor. I am having a friend take a TRC tire (with 6 holes) and drilling out the arbor and tapping it so I can just screw it on and no need for a clamp. And will have dead on balanced wheels all the time.
