Years ago Hendersons was recommended for alignment. When the subject comes up I've asked others about their experience. That's why I went there for shocks and a banging noise which resulted in watching and learning what they do and talking to other owners. I went in the pit as they and they explained what they were prying on and looking for, no problem. Alignment showed tow in problem and rear axle torque problem that was just out of spec and did not need resolution - cutting and rewelding involved.
From your post you might benefit from their Road Performance Assessment. Their work is pricey.
