Once again I'll post a test. Instead of just guessing it is this or that. You could of googled this test and called your self a professional and the rest of us idiots.
If its two wheel drive not for wheel and you wanna check it out. Jack that back end up put it on stands put some wood in front of the tires. Get a buddy or freind Start it up ,run it to you hear the noise get under there and listen to were its coming from. You can use a long screw driver or long pry bar put the butt up to your ear. I would just use my chassis ears but Im not with you.
Try it OP a real test to see what it is. Not a guess. But from my past it sure sounds like a pinion bearing. I suggest calling up jasper and talk to a tech and ask them why its the bearing not gears.
