vibration at idle

About a month ago truck started to have a slight vibration at idle that can be felt when touching the dash and can be felt in the steering wheel also at idle.Causes a low pitch hum in the cab.Lifted the hood and can feel the same type vibration on the intake tube going to the air filter from the manifold.Anyone experience this?Not sure what to look for.Is the vibration on the intake tube normal? If so some how its now effecting the interior by transmitting .It stock,no mods.

I have a 2009 with 1900 mile and have had the same vibration since day one. I have one near the passenger side which stops when I open the glove box. Not sure where to look and don't want the dealer taking everything apart trying to find.That damn dashboard is all cheap plastic and moves so easy when pressing on it. I think the vibration from the engine go into the dash...just trying to live with it for now.

I have the same symptom. It started after the dealer did a repair for a raw diesel smell during regen. I have not found out what causes it. I took it back to the dealer and they said that it sounded normal to them. I got tired of arguing with them and I have had that vibration for about 18 months now. It goes away at about 950 RPMs and up. Also, if I take a long trip the vibration is almost completely gone at idle. If someone has any suggestions as to what is causing it, I would like to know also.

There are alot of different vibrations, ticks, taps, that these trucks make, for a while at idle my dash would vibrate real loud. The only way to fix it was hold my hand on it. I deleted the DPF and nothing seems to bother me over the sound of the truck now. kind of an ignorant answer. but it worked for me.

Don't know how many miles you have on your truck but around 30K mine started a vibration at idle. I saw nothing wrong so I kept trucking. At 93K I read somewhere (on this site) that it is the belt tension pulley vibrating at idle. changed the Serpentine belt and squeak I had sense the truck was new at shut down just as engine stopped disappeared, and the vibration went away. Now with 118K the vibration is starting to come back. You might have someone look at the belt tension pulley at idle, in gear. Good luck.

Like many of you, I also have a vibration in the dash at idle (only). I have found that my noise comes from contact between the front edge of the dash and the bottom side of the windshield, slightly left of center of the steering wheel. It's hard to see up close at the point where the sound comes from, but it appears that there are some small pads on the front edge of the dash to prevent vibration contact with the windshield. Some of those little pads seemed to have dropped off and now I have contact and a noise. If I put my finger in that area, or a soda straw, or most anything that prevents contact, the noise stops. Probably could solve the problem with a little weatherstrip on the top front edge of the dash - just haven't gotten to it yet.

Second your answer....Its a diesel. You will probably notice that the vibration is more pronounced in the winter time/colder temps.

I have a 2009 with a little under 1600 miles on it and I have the same issue. I asked the stealer about it and they said they can tear the dash apart and spray foam it! WTF!!! I declined of course becuase I don't think I want any parts of a 3 dollar can of spray foam on a 50,000 truck.

I have the exact same annoying vibration in the dash, only at idle - had it from day one -drove me crazy and was same description as Ron above - anything between the two pieces of the dash near the windshield where the little felt pads are would stop it so I fixed it. Last weekend I popped the dash apart, rolled in a small piece of a windshield gasket (rubber, sticky gasket) got it nice and warm, pushed the two pieces of dash back together (had to do some thinning in areas where gasket was too thick) and then trimed off the excess - she's as quiet as a mouse - no rattle, no vibration, nothing.
