bad vibration in entire frame

[Pushit2.0]

We have a lot of mph info but no engine rpm info, what engine rpm does this happen at, and does this noise happen when you rev the car while someone looks under the hood for the noise. I would think its ither the front balance shaft belt or a problem with the clutch. Also when you miss shifted on the test drive what happened? 3rd to 2nd at redline in 3rd or what? Just take the car to someone who knows what they are doing, because it sounds like thats what you are going to do to get it fixed anyways.

My talon used to have a shake to it when I it was going 60-70mph, and had the foot on the accelerator. Didn't matter what RPM, just as long as I was in that speed range. Chromepuff on here knows what it felt like, he rode in the car once when it did it. If I let off the gas, it would mostly go away, but still be there slightly, but when I accelerated, it was the worst. Felt like the whole car shook.

I ended up injecting a bunch of urethane into my carrier bearing, and that took care of it.
