Not sure what to do about this, but here it goes: I have 97 Nissan Pathfinder. Now, I'm a relatively new driver, so this might just be something that happens to cars over time, and I just don't know it. Whenever I go over a bump of some kind, I hear a little squeaky noise that "feels" like it's coming from the suspension (I apoligize if this is incorrect, I do not know much about the internal workings of a car). The same noise also happens when my subwoofer is at a medium volume (enough to shake the car, but not so loud that I can't hear the squeak). I think it has gotten worse over time. Is there anything I can do to fix this? Thanks!
