Noise underneath driver feet

[STLstroker]

I don't know what exactly it is but it drives me crazy. There is a creeking grinding sound that i can here when going over small bumps coming from the driver side front end. I have taken it to the shop a few times for this nice and all they replace is some bushing or something. Not totally sure. But its been replaced two years in a row now and works for a little while then the noise comes back. Anys suggestion? All the suspension is stock with no lifts at all. Thank you for the help
