on my mate's hsp flying fish, one of the dogbones didn't sit far enough in the diff cup and caused all sorts of issues. i fixed it by a couple of 0.2mm shims on the inner wheel bearing side to move the dogbone closer to the diff cup, and a couple on the opposite diff bearing side, to move the entire diff 0.4mm over for a total of 0.8mm. after that, the dogbone sits nicely in the cup. and mesh still fine. the diffs for my vrx cars come with 5 shims, if you get them wrong the mesh can be too tight, and i guess usually its for adjusting mesh, but on this HSP, it really needed some shimming
Appreciate the info. Gonna get right on that. Think I'll see if ican just adjust it on the cvd hub end first. Never had the issue till I stiffened up the diff. Thanks again
