i was drivin down the raod today and went over a bridge, theres a bit of a bump at either end of the bridge. when i went over each of the bumps, i noticed that my tranmission, made a pretty nasty grinding sound, didnbt make a noise really except then. got to my buddies house, watched the entire race, started driving home, thought a felt a little vibration the whole way. left my house headed somewhere, and there it was, pretty bad constant vibration, except when i'm holdin in the clutch or in neutral. it almost seems as if the tranny has come lose or something and isnt sitting square like it should. i sure hope its nothing expensive or hard and def not the tranny itself. (i've had 2 inswtalled in the past 6 months... any ideas where to start?
to check your ujoint, twist the d-shaft, if you see any play at the ujoint, its bad. when my tranny mount was dead, it was the most noticeable on take off. when i bent my d-shaft, it was noticeable constantly but worse with more speed. check your weights on ur tires too. an out of balance tire can make it feel like the whole thing is coming unglued

I hadn't thought of it until I read what whitebuffalo wrote, but I have gotten water and muc inside my tires from off roadin'. If that happens, it'll feel like the whole thing is blowing apart, just like he said.
it was the u-joint near the rear diff..... i've now got another issue, it kind of shaved a good little bit out of the side of the yoke(?) going into the rear diff.... is this little bit shaved off going to cause any balance problems?
