weird vibration after 3 grand

[devulz]

im was driving home from the lake the other day and i stepped on it, at about 3200 rpm's i heard a really weird vibration behind me. from about 3200 too about 4000, after that it went away. it does it through all gears, but only on full throttle. i have no idea what it is, but it sure doesn't sound right. someone was telling me it might be the driveline, but that seems weird.

I get vibrations too driving regularly, it is a little discomforting to be driving down the highway at 60 Mph at 2k RPM and feel as if the car is going to break apart around you.

Exhaust system? Vibrations between front and back seats? They just repaired mine under warranty....

Probably your fuel transfer pump, pop the bottem of the back seat off and you will see a black plastic cover, take the 4 screws off and you will see the pump, drive around and have someone listen to see if its the pump (should be pretty ****ing loud)

It could be the diff too. When i hang the arse out in my car (oversteer, of course) and then hit the anchors to make it slide on all four tyres i get a serious vibrating noise out the back. Maybe your diff is nearly on the way out. Could be the transaxle too??

Good luck anyway.
