So I take a route where there is a stop sign. I have to turn right there. And right there on the right side there is a aggressive speed bump. I mean it seems like it's made out of those parking spot concrete wheel stops. So I try to go over it as slow as possible while making a full 90 degree turn. And no matter how slow I go over it there is always a loud grinding sound coming from the drivers side wheel. It sounds like two casting parts or two rocks rubbing against each other. What it might be?
