Thanks, that extremely helpful! Now I am going to drive around in reverse for a bit. Might even throw in a few J-turns Rockford style (J-turn - Wikipedia). Well, maybe not with such a dodgy transfer case underneath...I just had mine replaced yesterday - ~46k miles. You can feel it bumping while accelerating, like there is a small bump, jerk, skip with the inertia as you accelerate through through the gears. It was very noticable in reverse, and you might think it's the transmission. Since my bushings were shot to ****, and tried to pay attention to everything with how the car felt before I dropped it off. When I picked it up, it was night and day.
This is what a my dealer did to confirm....
Drive car (problem is present)
Reporgram control unit for xfer case and drive car (problem is present)
Unplug transfer case and drive car (problem is not present)
Confirmed xfer case needs replacement
