The eaton in my moser 12 bolt seems loose to me. Not Loose as in the clutches not grabbing, but loose as in the spider gears seem to have way too much play in them. Is there any known problem with this? I had the rear apart before to double check backlash and it was acceptable to me at 11 thousandths, and thats when I noticed the play between spiders. Is there supposed to be a certain backlash for these? Would I be able to shim this a little tighter? Any help is appreciated. Thanks, Sam
