8 3/4 vs 9" cost-wise
Stock non nodular 9" yes, but a billet aluminum no.
I have seen plenty of the nod cases do it also, and even some break the caps and stamp the housing.
If the 3rd bearing falters you will have even the daytona pinion come ripping out of the case, nothing can change it from happening if the 3rd bearing falters, all by design, that 3rd bearing suffers and the pinion can move just a bit, snap and forward it comes..
Happens a lot, but people
think the 9" is better, loading the bearings more than other diffs and carrier.
I am gonna have another one that just ripped itself apart tomorrow, and i'll explain to that customer step by step the pros and cons of that diff and he'll understand why when they break, they grenade everything (it also was a nod case, daytona pinion).
A dana, 8.75, 9.25, 10blt, 12blt have a bearing failure and you may need gears, those 3 will give you a warning, i have never seen them shoot the pinion thru the shaft and kill a trans though, i did see even the aam 14 bolts do the same thing, and even 1 of the amm modernized 14 bolts kinda get the pinion out of the case.
