360 Which components to replace to tighten up off-center steering play?

My 360 has always had a looseness to the off-center steering feel, especially under hard acceleration when the front end goes light, and it’s naturally more noticable at highway speeds. I haven’t driven any other 360’s to know of this is a normal characteristic of the model.
There’s no knocking or untoward sounds associated with it; my ball joints, tie rod ends and sway bar drop links have all been replaced.
Are there other go-to components that I can replace to tighten up the steering feel and eliminate the looseness and play off-center?

Thanks

A few good theories here.
I wouldn’t think it’s an alignment thing. I’ve had a recent alignment, and the car tracks straight. It just the dead spot on-center that can make staying straight difficult because there’s a degree of movement left and right before it affects direction change.
I don’t have a power steering rack, per se, but I had noticed some moisture around one of the boots at the outer end of one of the boots, but not an actual drip. I’ll keep more of an eye on that, but I’ve never had to top the fluid either.
I’ve seen a video on tightening that nut, and I have done it myself, but I was worried about tightening it too, as I didn’t know if it was a 430-specific issue, and I could end up doing more harm than good, but maybe I’ll give it another twist and see if there’s any more slack I can get rid of, unless someone advises me otherwise in the meantime…

 

My 2003 definitely has “a” 27mm nut there. I’ve tightened it before. I just don’t know if it has the same purpose and effect as it does in the 430’s.

 

So I tightened it up some more today and was able to get a few more degrees of movement from it without feeling like I was forcing anything. Went for a test drive and I’m fairly confident it felt tighter, though I didn’t have time to hit the freeway. I think part of the issue is I’m so used to to the electric power steering on my Cayman S daily driver, and I might need to recalibrate my expectations. But having never driven another 360, I can’t really say if it’s just normal and routine.

 

And that’s on a 360?

 

Good to know. Where did you send the rack for rebuild?

 

Indeed; that was my original question. I’ve already replaced the ball joints and the sway bar end links. What other components have the biggest effect on steering “play”?
