Hi All, first post here. I've just picked up my Kraton EXB and after researching the boards here, inspected the diffs to ensure I have a "V2" Kraton with the initial diff issues fixed. Turns out I do have the V2 version, with all limited slip diffs with the rear diff in the "minimal effect/1 face" configuration.
I've read threads indicating that all you need to do with the updated/revised Kraton EXB is check the fluids "and send it", and possibly replace the slip plates in the rear with specific shims for an open rear diff - a solution apparently identified on these boards and adopted by Arrma as I understand it.
However, I purchased a couple of spare assembled limited slip diffs (ARA310990), which are identical to the diffs in my EXB, and noticed that one of the diffs I purchased is much "notchier" than the other one that I purchased. It's also notchier than the ones I pulled off my Kraton EXB. By "notchy", I don't mean harder to turn; just that you can distinctly feel every tooth as you turn the out-drives, whereas on all the other diffs you can't really feel the teeth as you spin them. I disassembled and reassembled the notchy diff, and it remains notchy. Also tried adding fluid - and it's still notchy.
My first question is, is the notchy diff in need of shimming adjustments? If so, how - in the updated limited slip diff, if I went to thinner shims at the ends of the diff cup, in theory reducing the notchiness, then there would be too much play in the out-drive and pin - right?
My second question is, there is the smallest bit of play when I wiggle the out-drives - meaning the tiniest bit of slop underneath the pin where the two shims and o-ring are. This is just barely detectable, but equally present in all diffs. Is this okay?
Any advice is welcome! Hopefully I've posted this in the right area - let me know if not.
