Ok, my bro had been complaining of a grinding everytime he used his brakes, and excessive pedal travel etc, so I checked his brake pads and there aren't any! He'* on bare metal to metal. anyway, that isn' tthe question, just the story of how I found another problem.
anyway, there is a broken bar of some sort, looks like it might be some kind of stabalizer bar? There are 3 things going to the wheel, the drive shaft, tie rod (the one that goes to the PS rack.) Then a 3rd very large one, and that is the one that is snapped in half. What is this for? he had been saying that he has a sort of shimmy/popping noise in the front end when you hit bumps, so I'm assuming this broken bar is causing this? Any help would be appreciated since I have NO idea what this even is.
