More T5 hap-penis

[Frankenstein]

What causes a T5 to have vibration at highway speeds, the T5 I got supposedly has this problem, and I am curious if anyone has any ideas. I dont really want to tear it apart yet, so I am just looking for some educated guesses here.

I am assuming that this is in gear, and gone when in neutral (But not 100% sure)

Thanks,
Brian

Yes, but I was curious late last night when I found out what the problem was, and did not want to wake him, I am sure I will find out some time today.
