Yea the vibrating isn't in the steering its like In the whole truck lol... but it could be front end parts i suppose

Yes, i had a very reputable shop check the front shaft, velocity joint and all... and balance the shaft... made no difference and the truck still vibrates without front shaft in... but! It is worse with the front shaft in

I thought this, so i installed a full set of new rims and tires and its still doing it

If I am on the throttle hard I will not even feel the 25-32 one and will still feel the 55+ one, but I am slowing down acceleration by then.

Started this fall and has steadily been getting worse. I have checked the u joints and all feel fine, both front and rear. My next thing to try is to take my traction bars off and run around like that for a while and see if they might be out of adjustment. Towing a trailer only makes it worse with mine, and that is what my 06 does 90% of the time I am driving it.

This is how mine started, so bad you couldn't drive it.. mine got better with new rims/ tires... but since then i can't do anything to make it go away entirely

Mine started after I smashed a Honda with it, so I am sure it is something in the driveline tweaked. I have all new brakes, rotors, pads, front end including axle joints, steering, hub bearings, new front driveshaft and joints. The only things that have more than 10k miles on them are the rear driveshaft and its joints and the traction bars, which I think might need adjusted, they have been installed for about 75k miles or so. Mine is a hopping more than a vibration, so I feel it is driveline bind somewhere.

I think my transfer case output is shot. Little slop. How much is normal tho idk
