thanks.
is it common for that 'out of round' to occur all of a sudden ?
here in Canada we went from winter to spring driving lately and this seems to have coincided. that doesnt make sense to me.
it could be a tire and the bushings and joint.
will have to investigate this wkend.

I do hear a click now
when parked I turn the wheel right
and I hear a 'click' sound.
I do not hear this sound when I turn the wheel left, only when turning right while in park.
It is coming from driver side front, and it feels 'loose' while driving in that area

Besides tires being the issue, a bent rim would also cause uneven tire wear and the issues you describe. Driving into one bad pot-hole would mess up a tire and could most certainly damage the rim.

Yes, there is a TSB on clicking issue
Check this thread and see if these other aspects apply to you. It may be a wheel bearing issue.

But meanwhile for OP (allenst), reading this casually it seems like it could be any of front upper control arm bushings, a bad torn CV joint/boot, or a wheel bearing, let alone the tire issue possibles. I think it needs a first person experienced inspection to diagnose; arm chair diagnostics can't sort that precisely.

I can now add this...
today was first day you could drive with windows down.
I hear a new sound. You cannot hear the sound in the cabin--just when driver window open.
It's a high-pitched whirling sound. It gets fast and higher as the vehicle accelerates.
It sounds like rubber of metal rubbing as the tire rotates.
It's not 'get your attention as you drive by' loud, but audible with window open.

One, it is so good to see MP contributing again. But your problem is starting to sound like a wheel bearing to me. The bushings should not make noise if car is running staright over smooth pavement. CV joint also would be very loud turning.
Not sure why is is noisey turning one way and not the other.

If I'm parked. I hear like a loose click when I turn the wheel right.
The noise is not made in any other turning situations.
The bushings sound like a garbage truck over our roads. Our roads right now must be some of the worst in the western world.
it just sounds all jangly and loose when you run over some shallow rough pavement.
you are right that when on good pavement, even a smooth run over a speed bump, I hear nothing.
it's the low speed wobble. car literally jumps right to left as you slow and gets worse as you come to stop.
whats new to the situation is that high pitched rub sound that is tied to the wheel rotation.

Does the high pitched sound change frequency depending on speed? As in, at low speed its dull but when accelerating its pitch gets higher, and if you let off of the accelerator it dies down again?
Also, please explain the car literally jumping from right to left in more detail. Does it only do this in certain instances? Turning? over a patch of rough or choppy road? etc.
