Last nite it was wet out and I went to go over a speed bump. After getting over it the light was going to turn so I punched it, broke the tires loose a little, feathered the gas to stop it when it hooked up it made a squeal (tires) but as I was going through the light ( making a left) the rear started to shake as if I forgot to tighten the lug nuts.... I let off, then got back on the gas and it stopped... Same situation about 2 hrs later, tires slipped corrected it then made a right turn this time, and I thought the rear was going to fall out.... :think: Wtf could this be? I have a 4-6 could I of possibly twisted the rear downward so now theres driveshaft vibration? Or could it be something else??? It only happened twice and since... none.... Sorry so long, help me out here..

Not the driveshaft, you would have a vibration all the time. I would think more along the lines of something with the rear end, ring and pinion, gears and stuff. wierd.
