I own a 2005 Lincoln LS V8 and anytime I go over 40 mph the right rear wheel wobbles and causes the entire car to vibrate and shake. The vibration and shaking doesn't stop until I slow below 40. I just had the shocks and struts changed out to see if that would fix the problem and it didn't. I jacked up the rear right side of my car and my tire move up and down with ease. I think maybe I need to replace my ball joints or maybe the sway bar but I'm not sure and could use some help. I need to know what's wrong with my car and if anybody could provide me with some insight it would be greatly appreciated. Thanks in advance.
