Stand at the front of the car and sight along the edge. You will be able to see if the rear wheels or front wheels are angling the wrong way. Both front and rear should exhibit a little negative camber, meaning top of wheel is tucked toward the car. They should appear very parallel to the centerline of the car front to back. If that all looks good then you may have something broken, such as a sway bar link in the rear. YOu can also jack up the car and try to wiggle each wheel. There should be zero play in them.
