Driveline vibes will cause this. I saw from another one of your posts that you have a 2" lift, BL and MML. Make sure your driveline angles are correct.
Since you also have a Dana 44 and a 5-speed, like myself, even a 2" lift can cause vibes. If you go out and measure your drive shaft, you'll find it's only about 18 inches from the yoke to the tailshaft housing. A shaft this short will create ungraceful angles, even with a 2" lift.
