If you put it in N and it doesn't vibrate, it's before the trans. If it does, it's after the trans or chassis related.

Another thing to check is to rev it to the 2600-2800 RPM while parked, see if it vibrates. That will also tell you if it's engine or chassis related.

Usually, if it's RPM related, it's engine related, if it's speed related, it's a chassis issue.

I've seen people have pulleys and fans out of balance that they kept swapping for config to config, car to car, and it followed them.
