300 front diff flipped in rear for IRS = POP. Decently built 350 foreman motor and 27 vamps raped the poor little ring & pinion. - lol
Seems bracing the "snout" section of the carrier "cap" piece behind the ring gear made the carrier stay in place, thus the bearings and the housing held, and apparently the next weakest link is the ring & pinion. - I haven't got it out/apart yet, but there is no side to side slack anywhere and the pinion rotates smoothly.......about a 1/4 turn back and forth before any teeth find each other.
Looking at the earlier 400 big bear diffs right now, as they are very simliar physically(even accept the same inner CV = no axles issues), but have a 3.67 ratio. The 3.5% steeper ratio has a 9 tooth pinion which is a little larger than the 300's 3.80 ratio. Since I would have no problems going to 29.5 or possibly larger with my current gearing, the slightly steeper ratio won't hurt me for the planned 28's.

Saracasm - just another service I offer(lol). We all knew it would fail, it was just a matter of when. Didn't expect it to be the first ride.
Got it apart; the snout again broke off carrier cap, thus letting the ring gear "climb" the pinion resulting in the gear set eating itself and everything else. - I'm debating between machining out a billet "cap" piece for the carrier or just going all out and machinging out a full drag-car type spool to replace the entire stock carrier. I really think the snout deal is the only real strength issue with these diffs.
