2007 Dodge Caliber suspension problems

The contact owns a 2007 Dodge Caliber. The contact stated that while driving at an undisclosed speed, there was an abnormal sound coming from the rear passenger side. The contact looked in the rearview mirror and saw sparks coming from the rear passenger side. The contact pulled over, and upon inspection, the contact noticed that the rear passenger's side tire was inward and the cross member was corroded. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer.

The first indication of the problem was as I was driving at higher speeds (above 50 MPH). I noticed a definite shaking which I took to mean that the tires were not balanced properly. I had the vehicle checked and was told that the front ball joints, control arms and tie rods were worn out. I replaced these parts and the tires as they had begun to wear badly. I am now about to replace the same parts for the fourth time! There are also major problems with the rear suspension.
