How long have you had it, before it started giving you trouble?
When it is working right, are you generally satisfied with what it does and how it does it?
From what you are saying, it sounds like is the replacment is less robust than what you arleady have? Seems like that might defeat the whole purpose of upgrading; when something fails prematurely, most guys step it up a notch.
The Auburn cone type friction differental clutch, I've heard, is a step up from the factory 8.8 Traction-lok, which uses flat plates. I don't have any person experience with the Auburn, but I've mostly heard good things about them.
I would suggest that you have 2 possible solutions, maybe 3.
First step...If you take advantage of the swap, you could just run it, see if it happens again, then step up to a ful Detroit Locker (or soft locker). 2). while they are fixing the old Auburn, line up a buyer, and put that money toward the Detroit Locker. Basically, get out of it now (Auburn differential) while the "get'n" is good; might even make a enough to off-set some of the conversion cost.
Finally, if something was just wrong with the old (current) unit, the swap might leave you with a good long-lasting unit, no need to change again.
The answer to the first questions may help you decide whether its worth it. Like that old Kenny Rogers tune...half the game is knowing when to hold'em or when to fold'em.
Funny how factory transmissions and rear ends handle abuse...I know guys that have never cracked the case on their factory transmission or rear end, drive it like the car belongs to idiot step-brother and yet the car gives them no trouble. Maybe its traction, burning rubber with one wheel loaded and the other mostly free wheeling? Who knows. Luck o' the draw?
