I have had slightly bent strut rods before. A couple well placed hits with a small 2 lb. sledge and they straightened right up. Just roll them on the garage floor, it is pretty easy to see where they are bent.
Or you can do yourself and your car a big favor and performance upgrade getting aftermarket strutrods from P-S-T. Tey are on of our sponsors and give us a discount.They are heavy duty and will not bend unless you crash your car. Fully adjustable which will give you more caster adjustment on your alignment http://www.p-s-t.com/Products_2/Products/Strut-Rods
