Check your trans and motor mounts before proceeding any further.

Besides mounts, I'd check the rear driveline U-joints. (when the front is pullen it's taking some of the load.) On level ground with the wheels chocked, in neutral, You can see if you can find any play between the ears turning the rear driveline back and forth. Zero play! Also I don't happen to have tried it, but after a bit of a drive I suppose a bad one will be warmer/hot, compared to the other. Pretty common that they fail.

Yep. This Jeep needs some intensive "noggin pokin'".
