Straightening your steering wheel per the instructions on that website will take 10-15 minutes with just a wrench and big set of pliers to rotate the steering wheel adjustment link. EASY, don't even consider paying to have it done.
Doing your own toe-in adjustment is nearly as easy and takes nothing more than the same tools mentioned above plus a tape measure. And I kid you not with this and make no exaggeration, you can very easily set your own toe-in just as accurately
as the latest laser-driven alignment rack can. Just as accurately and easily. I can set my toe-in on the trail in a few minutes and have the same accuracy.
