ok the other day i was leaving work and i was goin leftand the back end felt like i had a flat tire you know how the car wiggles around on a flat tire it felt like thatbut i got out and look and everything was fine both tires were great so could it be possible that my rear end is moving around that somethin could have came loose . and also if i go any fast that 80mph my car shakes really bad and i think that it could also be caused by that . anyone with any ideas reply please

 

Take a look at your Panhard bar or Track Bar (depending on what you call it). This is what keeps the rearend centered. Don't overlook other rear suspension pieces though, including all the bushings and sway bar endlinks.
