You might check your center drive shaft. At first, the way you describe it, sounded like a noisy f-pump/filter. There is a fair bit of shielding under neath these cars. Pretty easy for debris to get stuck up there. You might also check the condition of your motor mounts since these car are so dependent on them. If the drive line has dropped, it can create a whole host of noises/vibrations.
