Archived Strange Vibration, '06 2500 2wd

[olznut]

I got my new 2500 last month, this is my first diesel and while I love the way the thing runs, there's a strange vibration that shows up at about 50-55mph once she warms up, and only happens under light throttle, and can feel it in the floor, and when my arm is resting on the door, etc etc. Once I tap into the power more or totally lift, it goes away. Something in the back of my mind tells me not to trust my local dealer, so would anyone be able to help me with like a few things to look at first before I take it in? I also notice she's got a bit of a what sounds like rocker arm tick. I can really hear it like when in a drive through, etc. Please help! Maybe a good dealer to take it to in So Cal?

I don't think I have heard of any problems on the later 3rd genners, I think there is a TSB out for the 2wd to shim the carrier bearing. Where in So. Cal are you?

Santa Clarita, just north of LA, pretty much I-5 and Highway 14. Where can I look up TSB's? It's not too noticeable, but it's driving me NuTz!! I don't recall seeing a carrier bearing on mine tho. How did you level the front, this thing has a SERIOUS rake to it.
