It's not uncommon to find stress cracks in the front section of the frame on the 88 and newer IFS GM trucks that are using snow plows. They are typically found right behind the rear most upper control arm mount. I have seen several situations where the frame rail broke right off in this area, and that was on 1/2, 3/4, and 1 ton models. As for the locking differential that GM uses, it's a joke too... it's the G80 code "Gov Loc". Also known as "Gov Bomb" These so called lockers in order to lock in require a difference in speed from one wheel to another in order to kick in. It's not uncommon to see these launch through the cover and splatter on the ground. All it takes to destroy a Gov Loc is getting stuck and mashing the gas a little too hard then BOOM! Pieces and parts everywhere! Tough trucks huh?
