Blkgs300

I have a 1999 gs300, when i turn the steering wheel slowly it makes a loud creaking sound coming from the front drivers side. This doesnt happen all the time but it usually happens at low speeds and when its not moving, it does not happen when it is on a jack. I think its the lower ball joint after i did the research but i dont want to buy the part if im wrong.does anyone know what it is?It feels like its cominng from this but cant pinpoint it

Can I ask you if you were able to resolve the suspension noise problem? If so what was it?
