Hey guys, not sure if you can give me an idea of what's going on or not but thought I'd give it a shot. I have a 2009 Silverado that when I brake, turn or accelerate I hear a knocking noise up in the front left of the truck. I also hear it occasionally when I go over a bump.

I have a call into the service department to bring it in but was trying to get an idea of what it may be.
