2002 Chevy Cavalier Soft thump in front end

Hi there
My new "used" car is making a strange thump noise in the front end that I can feel in the pedals and steering when I turn a corner

Started a few weeks back, would initially come and go and now seems to be more regular.

What could this be and will it fall under the dealers 90 Day Lemon warranty?

I keep hearing expensive things like CV joints etc. But the car had a full inspection 2 months ago at time of purchase. Also, the life span of CV joints is supposed to be over 100K

What else could this be?

Thanks
