*Thud* When Accelerating

So I've noticed that when the jeep is in park and I punch the gas to rev the engine a little, there is a heavy thud noise. I can't tell if it's doing it on the street, but definitely while in the driveway. Hard to tell where it's coming from. Anybody know what might be causing it? It only happens if I punch it hard enough to reach about 2,500 RPM.
