so I had my car up and the wheel off and I was looking at the suspension. The part I circled is "i think" the lower control arm bushing (someone correct me if I'm wrong).
Now, I apologize for the lack of focus on it, but you can probably see that it sits at a strange angle. The bushing appears to be a polyurethane type of sorts, it wasn't rubbery to the touch. Because of its strange angle, the bottom of the bushing touches the metal on the sides.
I have a really minor rear suspension crunch noise over speed bumps (that the dealer checked out and said was non-existant and my suspension was 100% ok). To me, it would make sense that these bushings rubbing on the metal would make such a sound, especially since there is no lube in the area.
