Bad vibration

[gooseman55]

i know that there is a lot of posts about trucks vibrating but the things that my truck is doing seems like i havent seen any other truck doing. When i get to about 50 MPH my truck gets a bad vibration to it. The vibration will stay there as long as i keep my foot light on the throttle. As soon as i let off the throttle or hit the throttle harder it goes away. I have some movement in my carrier bearing and my u joints dont look bad. The vibration is still there in 4 wheel drive but seems to go away when the truck is put in neutral. being new to diesels im at a stand still not knowing if the carrier bearing can still be problem if the vibration goes away in neutral. truck is stock except a 2" leveling kit in the front, any help is appreciated , thanks everybody

Does it have an aftermarket exhaust ? might be the downpipe causing that. cause thats somewhat how mine feels like.

ive been having the same issue lately but been trying to ignor it. Feels like its coming through the floorboard on mine. I cant figure it out for the life of me, thought it was a unit bearing for the longest time but i checked those, u joints, ball joints, out put shafts on the transfer case....and so on but no joy. Only thing i could figure was maybe it might be the tourqe converter or something in the tranny.... im gona keep any eye on it though.

No aftermarket exhaust. Ive tried looking to see if i have a possible exhaust leak. Everything looks ok. I dont see any cracks or holes anywhere
