when backing up on a steep incline or too quickly in reverse, the truck will pop out of gear and grind. i replaced all bearings in rear differential and the pinion bearing. ring gear appears to be fine. u-joints are new too. is this a transmission problem?

It sounds like a weak, or bad engine mount, or maybe a trans mount, allowing the linkage to pull the trans out of reverse.
