Sorry yours were that tore up, but those are supposed to be better diffs. Of course you'll still be shimming them??

When you beat one of these hard - lots of jumping - big air, nasty landings- both on and offspeed, diffs take a pounding. After you've made them good and strong - my diffs are in gpm alum diff cases (same ones as in the SAV how to) and inside gpm alum bulks so there is no twisting under load, start to see the ring gear side brgs wear more than other side. I've had them frag - fail badly, open it up and pieces of brg race and balls everywhere. I replace that brg every time I'm in there for whatever reason.

One fix - take ring gears to machine shop and have brg boss cut down to run 1/8th buggy brgs, 8x16x5mm instead of stock 10x16x5mm. The stock brgs use smaller balls while buggy diff brgs use bigger. Enough diff to fix prob. Nothing I run with 7.5 style buggy diffs (SuperMaxx, Lightning and FLM BL Emaxx) have ever had probs with those diffs or bigger brgs). I was disappointed to see my new Flux using same brgs.

Other fix is some kind of adaptation of one of the CEN diffs. Not familar with that one - yet.
