Thank you for the awesome replies. When I said that I have replaced everything I mean I have TRULY swapped out every part except the headset when I converted the bike from an SS Mtb to a geared monstercross bike.

Last night I removed the cranks/BB and I recorded a 30 second HD video of the bottom bracket "play" when it is 99% screwed in. The BB screws in smoothly and tightens appropriately. I will upload the video after I get home from work tomorrow.

Thank you for all of the input guys!
