Thanks for your help guys. This question was for my XXXT MF2 truck. I went to an old friend and he tought me a trick. There was nothing wrong or missing, I just needed to learn a couple techniqes...... :devil: :devil: .......now my diff is smooth as butter! :thumbsup:
What I do with all my diff rings is sand the surface so diff balls have a rough surface to grip. The smooth surface may not provide enough friction and until it all break in it may feel a little scratchy at first. After assembly is completed I then breakin tranny to get gears seated, then after a breakin 5-15min it's gets adjusted for racing.
