This is weird, just starting today, there's a sort of crunching/creeking sound coming from my wheel wells whenever I go over a bump fast enough to compress the springs at all. It's pretty loud, very audible from in the car but it feels no different. I'm absolutely sure it never happened before, and the only thing I did was wash my car yesterday. Is it possible for the water to make parts rust in there? Never happened before and I've always sprayed under the wheel wells...
