It was dead simple... I tied the end of the string to the rear tow eye which was about level with the center of the tire and ran it around the back of the tire at the center of the hub to the front, just get everything loose on the steering rod and make adjustments until all 4 points are lined up and tighten it down. I only jacked enough to get most of the tension off of the wheel, it was not off the ground, you still need some on it and it should be firm when your pulling it into alignment.
You can use the same anchor for both sides and once your aligned and snug up the bolts I lowered it then tightened it after a quick recheck..
All in took maybe an hour and 1/2 that was figuring out how to do it.. I just took it for a 20 drive, tracks nice and straight
