Symptoms of a Bad Motor Mount?

[bullfrogjohnson]

I was getting on the truck pretty hard yesterday and today I have noticed than when I get over 2,000 rpms I get a bad vibration up through the steering shaft and into the wheel. I have never noticed it before. It only does it when I am getting over 50% throttle

What do yall think?

I put my truck in drive and boosted it up to 20 or so psi. My engine lifted up about 4" in the engine bay. Right then, i knew it was bad.:rofl: You can pop the hood and watch while you boost it up.
