Lets say I split the damn case and replace the 3rd and 4th gear pinions, whats to prevent this from happening again? I see that a couple of bearings have new part #'s were they discovered to be the culprit of this overwhelmingly common problem? If not what was ever determined as the fundamental problem? I mean I have read post after post of this very problem, I see that alot of the posts originated in 04 is this just around the life expectancy of these parts, 4-5 yrs? What the F@%^k is the damn deal! Shit!
