I recently installed a new set of Pro Gears in my 12-bolt. I spent a fair amount of time prepping the gear set. I profiled all of the leading/trailing edges on the ring and pinion, bead blasted the set, used the recommended GL6 synthetic lubricant, set the backlash a little on the tight side (.008 vs. .010 spec) and setup the pattern to favor the toe of the ring gear. I also run an LPW support cover. The housing is a Moser with beefier caps and larger cap bolts.

I made a few passes last night and the set has a slight noise/howl on decel which I understand is normal when you setup a gear set to favor the toe. Today I drained the lubricant and pulled the cover to inspect the gears. There is a nice shiny pattern with no signs of galling/scoring but I did end up with fair amount of "molly" looking wear particals in the bottom of the case.

Would this describe normal wear for a pro gear? I realize the metal is softer to absorb shock which would lead me to believe this wear is normal. Thoughts anyone?
