I did the mod a while back and have so far had no problems with it. I used a small straight edge to make sure the washers were not ground down past the end of the axle. I colored the end of the axle with a marker, then (with the washer on) passed the edge back and forth across it...when it barely scratched off the marker, I knew I was done. Plus, I didn't torque the crap out of anything, just snugged it up nicely. Enough that i couldn't loosen anything by hand yet not so much that I mangled anything. Honestly, the hub spins better with the mod than without it, and mine doesn't have the play in it that everyone complains about. Time will tell if what I did was wrong, I suppose.
