Left Front suspension makes a squeaking noise

When i drive very slow i can hear a squeaking/creaking noise coming from the drivers front side. Also when i push up and down on the drivers side/left side of the car i can hear the same squeaking/creaking noise. Whats causing it?

Also, I don't know if it is related. Sometimes when pulling out of my driveway, at the very end of my driveway ( Which Dips down where it meets the road ) i hear what sounds like metal on metal grinding sound.

This ONLY happens when turning left.

I took it to the Lincoln dealer and they said they could not recreate the problem.
