i have the craziest problem, when i am driving at highway speeds up until cruising speed it vibrates and while im cruising it will vibrate. however, with no change of speed or climbing angle it will suddenly STOP. no vibes whatsoever. the vibe is much like a ujoint vibe i have felt. sometimes it feels like it will rattle your teeth outta my head and others its just soft. and when its off it doesnt fade away, its like a switch on and off. also when it begins to vibe really bad the gas pedal seems really easy to push down. i dont knwo if thats got anythign to do with it. also the driveshaft has been ballanced recently and i dont think they did it wrong. also didnt lose any wheelweights. WHAT IS GOING ON!?!

check your diffs.
trans has 14k and diffs are good! they rotate smoothly but it couldnt hurt to pop the covers.
