I would check your track bar. Make sure it is torqued right and the bushings havent failed.

Is it a vibration or a shimmy?

If it's a vibration It's likely a ujoint in your drive shaft. Front if the vibration is in your feet ish area, rear if it's in your back butt ish area.

If it's a shimmy which would be a side to side movement, think "washing machine unbalanced". If your shimmying side to side it's likely a loose connection in your trackbar, retorque it. Usually the axle connection causes issues, sometimes that hole is slightly worn out making the bolt loose.

The other thing that would cause a shimmy is your tires are not balanced.

Lastly I'd torque all your control arms again if you replaced them within the last year, I found the all of mine had loosened a bit.

Jack up the rear diff to where both rear tires are off the ground. Make sure she is stable and either give the rear driveshaft a good shake or stick a screwdriver check the U joint for play. Usually a vibration like that is caused by a worn U joint

ditto on the U joint, just had this happen to mine. The shake was there when you were on the gas, but as soon as you let off everything was smooth.
