Okay, so for awhile now I keep hearing this sound in my rear suspension (I think). It's when I go over bumps or potholes (there are a lot of them here in Eugene Oregon). I am thinking it could be because I have a Toyota Paseo with big, heavy, 17X7.5's....the car doesn't have heavy-duty enough bushings to handle that much weight on bumps. Has anyone else had this sort of problem, maybe any advice?
