I'm trying to collect the parts to do the tie rods on at least one side, but there's a new problem now... something is loose behind the left front wheel and sounds like it's alternately hitting and scraping against the brake disc. On a rough road there's a lot of clanking, on a smooth one it sounds much more rythmic (and gets louder in a right turn). If I stab the brakes it will clank, then go quiet, only to fade back in. When I poke around behind the tire everything feels perfectly solid, which leads me to believe that somehow, I have a loose brake pad (only thing I can't directly check with the wheels on) on the left front? So, my question is, how do I get at the brake pads, and what other problems am I likely to find once I do? What would break to cause this?
