And having changed a rack and pinion on a Sentra, MUCH easier to do

. A lot lighter also. I imagine a lot of the problem is when something gets moved and the assist computer's placement of wheel center is not where wheel center is and it tries to correct it. Working on KIA, a couple customers have had their vehicles aligned and had similar problems. KIA uses a light to alert the driver, and it is a simple matter of resetting the center to center in the computer.
