2004 Jeep Wrangler Vibration

The fluid level is full. Right. You might try checking the front driveshaft, around the yolk area, these often wear and will cause this type of vibration, you can try to move it around in all directions a very very small amount of movement is most cases ok but not alot, also ujoint in driveshafts bot transfercase and front and rear. Has the jeep been lifted? This can change the angle of the shafts cause excessive wear, and create a vibration. Hope some of this helps. Alot of things can cause this.
