Yes. Hamsterpower said it better than me. Don't try to hold a wheel when any kind of power is applied.
I get about 1/8 of a rotation on my wheel, with the other wheel held or on the ground, and the input shaft of the transmission isn't turning. I'm not sure how much is acceptable. Excessive play is one possible explaination for the noises when you let off the throttle.
