ya it only the outdrive splines that are stripped not the actual diff itself.... I tightened the diff right up when I built it and then checked the other night when I took it apart and it was still nice and tight... oh and i had put extra spacer in the outdrives as i read on here that it seemed to help....and I am running the cvds as well

kinda bummed out that I spent as much on it as I did and it only essentially worked maybe half a season

oh well
