Welcome to the forum. A lot of people have experience vibrations of diffrent kinds. Can you be a little more specific? Is it coming from the front or the rear? Is it a hard or soft vibration? Is there a sound associated with it? It could be coming from a lot of diffrent places like the exhaust, the driveshaft, the rearend, the transfer case, etc. If you type "Vibration" into the search bar it will pull up several threads on this. Let us know a little more and I'm sure others will jump in.
