I was driving down the highway at 50 mph when I heard a loud noise coming from the back passenger side. Then I felt the car go out of control and I managed to safely get the car to the shoulder. My passenger door side airbag came out. When I got out of the car my tire was almost completely of the rim. I had my car towed to the repair shop and they said I needed a new axle, wheel bearing, control arm, rotor, rim and tire. Upon further inspection they realized the rim went through the underside of trunk and damaged battery and electrical components. They estimated it would cost about $3,000 to fix not including the body damage. I just replaced the right front hub assembly and control arm in Feb. 2011. I have replaced engine coils and valve covers numerous times.
