I bought the lude with bad alignment so when I went to get it done at a shop I was told the rear toe bolt was rusted where it couldn't be adjusted. My right toe is eating my tire fast. Is this adjustable bolt located on the (right) rear control arm? If it is which bolt? Is a replacement of a rear control arm hard? I have a buddy who can replace the control arm so I can get the alignment done at a repair shop. Any info would be helpful. Thanks.
