So I've finally had a chance to lift the front end, but I'm still confused. If I grab either of the rack ends, it feels like I can jiggle them a tiny bit, but I can't see any play. I might be able to jiggle the right side a little more than the left, but this is hardly a scientific test. (The part of the tie rod end that sticks into the ball joint can't be moved by hand at all.) Is this normal, or is that a sign that they should be replaced?
Furthermore, when I look closely, I can see that the tires do move a little bit when I wiggle the steering wheel, so it might not be steering "play", precisely, but it seems like the tires should be moving more than they are. Am I just not used to the NSX steering ratio? Can I tighten it up by performing the steering gearbox adjustment?
