Having trouble with my car, the rear tire (driver side) collapsed. when we jacked the car up and took of the tire we saw a part that was like a horseshoe shape, and it was broken, we have no idea wat the part is called, and were trying to avoid taking it too a mechanic cause wed have to tow it and the charges would be huge, so maybe if ou can give me a link to the schematics perhaps or something, thank you very much. (we cant find a duplicate of the part anywhere online)
