Strange feel in 4-HI

Took the jeep down to some trails along the Arkansas river here in Tulsa, Ok. I left it in 2wd until the sand became so heavy, the back wheels started chattering and bogged the motor down. When I put it in 4-hi, I could feel something odd in the floorboard, like something was loose. Every little dip or bump I'd hit, it felt as though the TC and front DS was really shifting around under there. I've never really noticed it before.
The 4-hi worked great, and so did 4-low, but something just didn't feel right. There was no noise coming from under there....just the feel.
Should I be concerned or am I over thinking it?

Check if the ujoints are good in the front DS. Any leaks from TC or front differential?

Check the transmission mount under the skid plate.

I haven't checked the trans mount. I'll check it out. The U-joints were relplaced about 3 mos ago. I don't notice anything until it goes in to 4wheel, so it obviously has something to do with the torque of the front ds.
This jeep leaks absolutely nowhere. I feel pretty fortunate about that.
