Here lately i've been developing a problem with my car not wanting to start. It used to just start up fine, no sounds, just turn over once or twice and it started up just like that. 2 days ago is when it really started getting bad. When i try to start it, it makes this god-awful sound. I dont even know where to start trying ot describe it, but its ugly and incredibly loud. the sound has been getting progressivly worse; the sound getting louder, and one time last night it wouldn't even turn over (just made the terrible sound). So i slide up under the car real fast acting like i know what im doing, mess with the starter to see if its loose or something - its not. Luckly when i tried to start it again, it started. Other than making sure the starter is tight, what should i try to do? Could it need shimming out? I don't understand why it just suddenly starting happening, and getting worse over the course of a few days. Any ideas?
