HELP!! need experts advice on 440 trouble.

Thanks for all the ideas, Im preparing cold coronas and will start checking each item you have all thought of, this community is great. I wish there were some good ol' Mopar boys around my neck of the woods who could just come over and listen to it. I live in Clover, SC...is there any rare chance that somebody from FABO lives near me....Cold Beer and $50 cash to diagnose this noise!! How cool would that be.
