So my son and I are in our first year of the BSA PWD, and we've had fun putting the car together. While going through the steps, I think some of our axels may have gotten a bit out of round. I notice while adding graphite that there is a slight wheel wobble. Not sure how much is tolerable but 2 of the wheels roll smoothly, and the other two have a little bit more of a vibration.
Weigh in is tonight, and we don't have huge expectations other than to be there, and have fun, but to minimize any negative performance what is the rule of them on wheel/axle placement?
Where should the smoothest rolling wheels go? The front or back?
