I have a 96 Subaru Legacy that the drivers side front suspension is making annoying popping, clattering and banging noises but nothing is loose or broken, and it still drives fine. I have replaced most of the front suspension parts at least once to try to fix it and taken all of it apart to inspect the parts and put it back together and nothing is visibly wrong. It's a bit concerning because especially driving on a washboard road it sounds and feels like someone under the car beating on the floor with a hammer. Do I just ignore it because as far as I can tell all the parts that could cause a dangerous failure appear ok? It seems silly to get rid of the car just because it sounds bad but I don't think fixing it is possible because I can't find the problem.
