Default Deep vibration

I am getting a deep bass like vibration coming from the rear in between 55 and 60 miles an hour. I just did a five tire rotation and had all five wheels balanced. Two weeks ago I did do rotors and pads in the rear but I don't think that has anything to do with it. I have a 2010 JK you with a foreign a half inch lift 37 inch MTR's and I still have my stock rear driveshaft. The front was upgraded two years ago. Any help would be greatly appreciated I'm thinking it's the driveshaft.

Does the vibration stop when you let off the gas?

It doesn't matter if I'm on the gas or not. That's what's throwing me off

I wish I had the time but there's no way I'm gonna be able to pull the DS before the weekend and test drive it. Going wheeling ha

Doubt it is the driveshaft. That would be a higher frequency. More like a buzz usually with vibration. Do you hear a clanking sound when let off the gas? Does it resemble wind buffeting? Kind of like when you roll a window down to just the right spot? Try changing the AC settings like vent or recirc and different window positions. If the sound changes with different air settings, inspect the vent flaps on the tailgate. If not I would inspect the wheel bearings and axle shafts.

No clanking. It's sounds like the car next to me is blasting base but I guess it could kinda be like a wind buffeting. Ill definitely check that and thanks for the new idea.
Rear bearings are barely a year old. I just upgraded last fall but I'll pull em when I get a chance and take a look.
I'm not overly concerned cause I don't actually "feel" a vibration it's more like a hear it but it's such a deep sound that I feel it a bit like base. Ha sorry best descript I can do

Nothing has changed with either DS so it can't be that
