Both my 3 gen 4runner and and my father's '05 4dr Tundra are expierencing a quite obnoxious squeaking. The sound seems to be coming from the rear suspension area. Sound cannot seem to be pin-pointed. Usually heard hitting small bumps. Any ideas what this might be or how to stop it?? Doesn't sound threatening or like major mechanical issues, but very annoying to us both!
