Sears tried to convince me to pay $200 bucks to have them install and adjust the bolts when I got my alignment recently. Its just barely out of factory range. How are are the bolts to install? The alignment is still under warranty so if I install the bolt and take it back in - they will readjust it since the tow will go slightly out again. I drive on the the interstate a lot, and I hate even the slightest pull to one side.
