Pulsing vibration help!
On a 03 evo 8.
Going 55-60mph (over that and under that it goes away) I get a pulsing vibration. You can feel it through the seat and not through the wheel. I thaught it was one of the rear lower control arm bushings because those had play, replaced those and that was not it. I also replaced both front wheel bearings and that was not it.(needed them anyways) I checked bal joints and tie rod ends and there is no play.
Im leaning toward it being somthing in the drive shaft, bushings? Any other ideas?

Slop in the drivetrain due to normal wear (for an '03) and buffeting of air moving around the body of the car, both at the same frequency. So, the sound/vibration builds up until you can hear/feel it.
You could throw money at the transmission and the transfer case and probably eliminate it for awhile, maybe permanently, or live with it. I'm doing the latter.
