2005 Nissan Altima Q&A
2005 Nissan Altima Question: Why are my back tires leaning?
You almost certainly broke or damaged some suspension components. I couldn't tell you how much to expect to pay without knowing how extensive the damage is. Best to have a good shop take a look and tell you specifically what needs to be replaced. - matte
I agree with Matt. Something is badly bent. May be best to have an alignment shop check the car first to see how out of specification the camber and other alignment figures are. They may refer you to a body shop to ensure the chassis is not damaged or bent. - patrick mannion
The car could have bent a rim, or damaged a lower a arm, or even broke a rear strut, if you take a close look underneath and see nothing different than the other side chances are you just bent a rim, a new steel rim is usually about 60-80 dollars - Tyler94
