Have you tried replacing the thrust bearing with the 1/12 diff spacer (part # 75296)?
You also replace the 1/4x3/8 unflanged bearing with a 1/4x3/8 flanged bearing. But you install it from "other" side of the outdrive instead.
i.e. The old unflanged bearing goes in the "diff ring" side...the new flanged bearing goes in through the "diff nut" side.
You use the same cone "belleville" washer and diff nut. You're basically making the diff work like a 1/12 scale.
I'm sure this mod has been covered somewhere else in this thread.
