vibration while accelarating from stop or speeding up?

Question

I have a 97 caravan with 3.0 engine. The car vibrates when I accelarate hard or moderate from a standing stop or when I punch it from and on ramp or uphill. I have changed the shocks, link, cv-joint on the left side. First it seem like the noise was on the left side but it seem to be coming from SOMEWHERE in the front. I thought it was from the left because I was in the driver seat but when I sat in the pass. seat and my wife drove it seem not to be from the left but instead it seem to come from ALL-OVER the front.

I now suspect the HUD & Bearing, or Harmonic Balancer.

What are the symptoms of a problematic harmonic balancer.

and the symptoms of a bad hud & bearing

If you power break it with out moving the vehicle does it still do it? (eliminating misfire from drivetrain). Have you rotated tires front to back to eliminate a bad cord in one of the tires? And if it is in the drivetrain take a good look at the right inner cv joint. if that joint is badly rusted up inside the boot or has play in it. it will cause a bad shake under a load and will go away as the load is gone.

I will try power braking it; did not try thay yet!  I took a look atthe right cv joint and it seemed ok.  No shaking or rust, but I willlook again.  I am about to change all tires on the car so I would seewhat happens.  my wife mainly drives the car so I hardly get a chanceto be around it.  I do drive my own 96 GC se  with a 3.3L.  I will tryall the above this weekend and post the results.  ANYMORE FEEDBACKS AREWELCOME
