Strange noise while turning right on 2002 Sonata

My wife has started noticing a noise coming from what sounds from the
driver's side front when making gentle sweeping turns at medium speed.
Kind of a "whomp-whomp-whomp". I was finally able to notice it too;
there's a slight vibration coming back too that you can feel. It seems
to be only while the steering wheel is turned to that exact position -
any more or less, and it goes away. We don't notice it on sharp turns.

I looked around under the car and didn't notice any obvious damage on
the front suspension components. Has anyone had a similar experience
or have an idea what might be the issue?

 

Could be CV joints or some other part of the front end. You won't see damage
just looking under the car. A competent mechanic will easily diagnose the
problem

 

What condition is the tire tread in?
