    I have a 2005 2.7l automatic and I have had this problem since I bought it new. I have had it in three times and three different service managers have told me it is normal, everything checks out.

    When I am sitting in drive at a stop light, after about 30 seconds a vibration sets in and continues to build to a very annoying harmonious vibration that makes the antenna wiggle.

    Slipping it out of gear makes it go away. So I suspect it is in the drive train.

    I did a search but could not find this mentioned in the forum.

    Anyone have a problem like this?

    Thanks!

    Your 2.7 LOVES to breathe and it posesses the same easyflo exhaust as the six..just my humble opinion..your exhaust system develops a vibe-and as you take the load off the engine you throw the harmonic off.

    I am not sure I understand exactly how the exhaust system makes it vibrate when it is in drive.

    So what is the solution?

    When you are at idle in neutral the rpm's are slightly higher because there's no burden. When you put it in drive, there be the burden which slightly lowers rpms, exhaust load becomes a little more intense, and your exhaust system being long and taught anchored to the frame with rubber mounts can develop a harmonic vibration at a certain load/rpm. I would take it to the dealer or a muffler shop to have them eyeball it in action and see if they can reconfigure a mount or add one. One way to check it yourself-CHOCK a tire, put on the e-brake tight, run it in drive, lay ALONGSIDE the truck (not in the tire path) and watch things underneath. You might see that exhaust problem yourself. I could be wrong here too- I can't see your truck. But it does sound like it.

    Thanks for the suggestion. I will give it a look. I would not have thought that the exhaust system, being tied to the frame in many places, would have enough free mass to to do that, but sometimes it doesnt take much.

    Anybody else have a theory?

    Well, its not the exhaust system.

    My mechanic suggested that the idle configuration be adjusted by a dealer, since they have the computer to do it. Since I have had it in 3 times for this and everything was "in spec", I doubt they would do anything different.

    Any suggestions?

    I don't know if I have the same vibration as you, but it started two days ago after the truck went back to be under coated and rust proofed. Started it up in the garage and when I put the automatic tranny into reverse I heard it. Sounds like the tail pipe vibrating on the rear fender. Should the pipe be touching the fender? The fender does have a curve or recess above the pipe, but I can't remember if it was touching before.

    i have the same exact problem as you hot brass, my truck as done this for as long as i can remember. when it gets bad enough i can here what sounds to be like my tail pipe hitting something which it could be since my exhaust isnt stock. but when i look at it, the pipe is not touching anything and its tight enough to where i cant shake it. but i believe it could be the exhaust. ill try the parking break idea in the next day or so and let you know but i would like to get it fixed because it it annoying
