Remy- Thanks for the link info. I do think it's tire related and I finally got a spare tire last week, so I'm going to change out the front tire and see if the problem disappears.
Greg- I did try tapping on the steering stem collar nuts with a hammer and a drift punch to snug them up, but they wouldn't budge, so I'm assuming they are tight at this point.
I'll try changing the tire first and then work from there.
thanks, guys.
