Vibration

Hi all. I have an 08 F250 with the DashDaq running th 210 tune. I had the truck lifted with a Fabtech coil over kit (8") and am running 37" Nitto Terra Grapplers. After the lift, I have a vibration that no one can figure out. It is at idle and it resonates through the cab. It feels like an ultrasonic vibration. You can feel it on the steering wheel, doors, dash, change cup, etc. It doesnt matter if your in neutral, park orin gear it is still there! When your driving it is less noticeable, but still there. This is not a driving vibration, but one when stopped. I swear it wasn't there until the truck was lifted. Any help or ideas would be greatly appreciated.

Wow. That sure is a perplexing problem.

I don't know jack about lifts, but is it possible that something is resting against the motor? There would be no other reason that I can think of that you would get a vibration like that and have it coincide with your lift.

Here is a for ya.

I haven't taken the DD out and replaced the stock pipe, but I am positive this vibration was never there before the lift. The shop has looked and looked and nothing. Fabtech says they have never heard of this vibration either. If you touch the coil spring in the middle, it's real noticeable. The higher or lower you touch on the spring it is less noticeable. It is driving me nuts! Thanks for the input.

Were the tuner/exhaust and suspension done at the same time? (Making it harder to know which started the issue?)

Make sure your complete exhaust system is not touching anywhere!

The tuner/DPF were done a few months before the lift and there was no vibration. I'll have them double check the exhaust! Thanks
