I was driving my z yesterday and i noticed a consistent vibration when i was coasting... now all of a sudden it has gone from that to a out of control gyration that shakes the whole assend of my car even at like 15 mph. does anyone know what the hell is going on?

take your wheels off and have a look, it could be as simple as your lug nuts being loose ;0

i can only hope so.... i am so scetched out tho.

could be a number of things, wheels out of ballance, driveshaft out of ballance, bad u-joint, bad cv joint, carier bearing, could be a diff mount, pinion bearing or wheel bearing

wheel out of balance - seems too sudden and severe for thatdriveshaft out of balance - possible, but usually midshaft bearing wear comes on slowly, unless the driveshaft took a hit or one of the midshaft bearing mounts brokediff mount - could definately be that toowheel bearing would grind and squeak and then sieze rather than shake violently

have you had a chance to get under it and have a look at it yet?

somebody tried to jack your rims! (that or you lost one a while ago and the second one finally loosened up and came off).

Broken studs will do the same thing.
