Sorry to hear that toms500 Usually the main shaft/u-joint will break before the output shaft/pinion shaft, and judging by the "clean break", i'd say it was defective - it should show signs of "twisting" if it was a stress break.
Like TrailRunner said, I use ice chains on my 500 2x4, and run it hard - need to if I want to keep up with everyone on 4x4's - haven't had any problems yet.
