Squeaky left front end

I drive a 2003 Ford Explorer Sport with approx. 53,000 miles on it. Recently I have noticed a squeak coming from what I believe to be the left front end. It is apparent when I go over bumpy terrain and apparently, as I found today does not squeak when I apply the brakes going over the same terrain. Lube work needed? Ball joint? I need some input.

Thanks,

Banks

You’re looking in the right direction.

Perhaps a worn bushing?
