Dang I'm really sorry to hear that, man.

Good point, I heard that the pre-12 trannys and engines are a little under-engineered for large tires but you'd still think that with 3.73, 35s would be drivable. While I was waiting to save up for the regear, I ran with my 3.21 gears and 35s for quite a while with no issues. I guess the tranny and engine improvements for the 12s made the difference, hell my wife actually wheeled with her '12 on 33s with 3.21 gears a couple times with no issues.
OP - I don't know if you have any experience with regearing. I'm like 99.99 percent sure that the carrier for the 3.73 gears is compatible with 4.56 gears, so it shouldn't cost that
much to regear if you have a buddy who does it or you're willing to take on the task yourself. I went from 3.21s which required a new carrier so it was a bit pricey.
