Rear end issue?

I'll admit, I tend to over analyze every noise or rumble in my vehicles, but I'm a little concerned about my truck.

ALMOST every time I accelerate, I get a weird sensation in the rear of my truck. I'm not a mechanic, and don't know the proper terms but if I were to describe it I'd say it feels like maybe the wheels are spinning, but they shouldn't be as it's on dry pavement, Falken ATW3s. Or sometimes it feels like maybe I'm shifting to 2nd gear at 5 miles per hour, because when I use ETC power to hold gear a little longer I feel like I get the sensation less often.

Again, I'm clueless, and plan to bring it up when I get my next free oil change. But any information I can get may be helpful.

 

Interesting. Never heard of an issue like you described before.

 

Sorry, I could be describing it incorrectly. IDK how to put it any better, maybe like a hesitation off the line? It starts to accelerate and almost immediately I get some sort of feeling of hesitation in the rear or a VERY brief pause in acceleration before it picks up in the RPMS. I've driven a lot of vehicles, and drive my wifes car regularly and never have any issue with off the line acceleration.
