2001 Hyundai Sonata 6 cyl Front Wheel Drive Automatic 68000 miles. The vehicle was broadsided in the area of the rear wheel. The wheel is leaning (neg. Camber) about ten degrees. What component would fail first? The arms look and I believe the curvature of the spindle failed?
You will have to consider all the rear suspension components, and the strut top mounting in the body. The most obvious would be the stub axle assembly, lower control arm, and trailing arm. You will have to have the rear end alignment checked as a Deg or 2 will be enough to destroy a new tire very quickly and give driving stability problems as well.
