They have been working on a fix for over a year already i beleive, maybe longer. When I was searching around to see if they had ever improved the design that was apparantly problematic, I found something, but that was a while ago (at least a year, did my 8.8.. gears, locker about march last year).
Do you have any lockers? I run an Eaton Elocker in my D30 and love it. Ford LSD in the back with the carbonfiber disc pack & S spring and it works good, my main limiting factor is probably the 33's. I understand being in Denver you're probably trying to avoid doing a lunchbox locker in the rear.
