Most posts asking for automotive repair help usually start or end with something like "I'm not very mechanical" to mechanically minded people this means "I put in gas, turn the key, and it goes where I want it to" most of the time. And the explanation of the problem in question usually follows suit, something like "it keeps making a noise up front when I turn, stop, or start" this makes a correct diagnosis very hard to give.

If your a car guy the following websites probably wont reveal any new secrets for you, but if your unsure of how this mechanical contraption works and you want to learn a little more on what happens after you turn the key heres some sites that can help out.
