For that price I would take a round trip plane ticket from here to there and back. Wow that is expensive compared to here. I changed mine today for a total of $42.00.... Serious.... The alignment is simple. If all your four tires are the exact size make sure all four have same pressure. They should not be "out of shape" Take a string and tie it to your rear chasis behind the rear wheel.. Bring the string across the rear tire all the way to the front tire. It must go over the center of both wheels. If when the string touches the side of the front wheel nearest to you, it also touches the front side of the rear wheel, and the rear side of the front wheel, all at the same time then you have a 99.9% alignment. If confused pm me.
Sorry that should be $242.00
