It is my understanding you can only adjust Toe, which can be done at home. Even right on Iron Rocks Tie Rod page it says: **Steering toe-in adjustment needed after installation. While a professional alignment is best, this can be done successfully at home using a tape measure.** So what all are shops doing for a minimum of $70? I paid at the dealer next to my work and got a refund as they corrected nothing. So what are the facts here? I have a new set of 33s about to go on, would like them not get all chopped up like my 31s
