Are you referring to when you press the output shafts onto the spider gears you end up with play?

I remember having that problem, and asked KAAZ and Bill, and neither could help. I ended up doing something to fix it but for the life of me can't remember. (I think I might have used a different cir clip) I don't have endplay and it doesn't leak.

But your using an 02A right? so maybe something is different in relation to output shafts on 020.

Going to test breakaway torque this weekend and will post my findings.
