I am hearing a loud squeaking noise when I am driving. Sounds like a large old rusted spring. I can hear it more when I'm in park and turn my when left or right. I narrowed down the noise to the driver side front wheel well somewhere. Sprayed liquid wrench underneath, but that did not help. I also hear it when I jack up the driver side front tire. Any suggestions?
