95 intrepid, 3.3 front end vibrates on the highway over 55mph, but only when accelerating. Rotated tires, no change. When in neutral, no vibration. The threshold for the vibration seeems to be getting slower as time goes on. Did change driver side half shaft that that had loose CVJ and wheel bearing (destroyed when pressing out stuck shaft) with no change. Transmission or engine problem? Help?

sound like a bent rim or bad tire

I assumed I eliminated a tire/wheel problem by not having a vibration when the car is in neutral and still moving at over 55mph? I have more vibration as I apply more throttle. Any thoughts?

It's probably your driveshaft. Had same problem on another car I had. Cost is prob around 2 - $300 used. Hope this helps.

when was the last time you had an oil change for your transmission? What you are describing sounds like torque converter shudder, occurs when the fluid starts to wear out and when the TCC starts to apply (normally that's around 38-45 MPH) you feel it applying. If you are using it already, run Mopar ATF +4, and try getting your system flushed out, that should help.
