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..
