Maybe your timing marks are off or your damper has slipped? I dont know much about mopars but I know my Chev has a two part (inner/outer) damper with an elastomer insulator between them. Have heard that the outer ring can slip. Check your timing mark, correct any problems, and use a timing light. Forget your ear...at your age, your hearing may not be as reliable as it once was...
