07 hemi driveline vibration problem

This just started in the middle of a road trip (while driving)Thought it might of been ice buildup on the suspension, but after defrosting, its still there.
07 hemi w QDII 83k mi, 2" bb lift w stock rubi rims/ tires, bilstein hd & MLL's

Symptoms:
Vibration in the steering wheel, cant feel it in the seats or console.
Vibration is audible, like a subwoofer steadily on
Most noticeable between 55-70mph
Only happens when on the gas pedal, instantly goes away when i let off
Sounds the same in all gears and engine rpm, only happens at speed above

What ive checked:
Diff bushings show no cracks, diff doesnt move
Didnt lose a wheel weight
All steering components are tight
Sway bar bushings and links are tight, no cracks or play
No mud or ice buildup anywhere
Tire pressure is even all the way around
No pull left or right

Anyone have any ideas of what else i could check? I really dont want to pay for diagnosis

Thanks

Re: 07 hemi driveline vibration problem

I'd check the wheel bearings. Does the sound change at all when cornering as the bearing is loaded and unloaded?

These can produce a low hum and produce a vibration when really bad.
