Warm up vibration

[Farmer Fran]

SO I recently got a vibration in the truck during the first few miles at speed, I go about 20mph for about 1 mile then hit 45 to 55 and I get a vibration (for lack of a better explanation), It is not in the steering, it is not in the brakes, nothing is loose that I can tell, the tires are at the correct pressure ETC...

After about, maybe a few miles, it stops.

Is it those darn active ant-vibration Whatchamacalitz?

You ever figure out the vibration?

I think it is the main road by my house.
