this past weekend i had a rear end failure due to 5 of the pinion gear teeth breaking. this is not at all an uncommon problem with this differential (currently the only legal one), just this weekend 3 of us had failures, and another had a problem that was caught before it became catostrophic.
there are other problems with the LSD unit itself, but specifically referring to the ring and pinion gear, i'm looking for a way to keep this stuff from breaking, as it's just too expensive to replace on a regular basis.
i was thinking of sending them off to be cryo treated and REM'd. cryo would hopefully harden the material, and a REM on them would hopefully reduce friction and thus oil temps, allowing the oil to work as it was intended. although i don't think oil breakdown is our problem (mine was certainly not cooked when it gave up the ghost).
i'm looking at you engineers and materials experts as to if this is a legitmate solution to a rather significant problem. i'm also not in the least concerned about legal issues regarding these treatments, so please keep that discussion for another topic.
