Strange knocking in front driver wheel well?

:
2003 Mazdaspeed Protege
Im sad I've had to post two different help topics consecutively. :/

It started a couple days ago, and is a consistent knock (Probably about 2 times a second at 25-30 MPH) and when I turn left, it is louder and more agressive, but when I turn right it ceases. Also when I'm coming to a stop it sometimes sounds like plastic being pushed around(Kind of like twisting an empty water bottle) and other times sounds like two different metal pieces scraping together.


anyone have any ideas?

Thanks.
