Knocking sound in front of my car (Chrysler LHS 1999)?

Today when pulling out of my insurance companies driveway for my auto insurance, me and my wife heard a clunking noise and the noise started to sound like something flapping against the engine block/front of engine. I drove maybe 200 hundred ft. then stopped, popped the hood, and nothing wrong from a spot check, no fluids leaking, but burning rubber smell. Start to drive again and a knocking noise started from the front end of the car when I drove over 10mph but not when going uphill. Got the car home, checked the belts in the front and they are all in one piece. No knocking/engine running a bit high (little over 1000 rpms in idle), but once driven, it starts up. Took it to local Chrysler dealership and the half stupid guy said it would probably be "something" with the crankshaft... But didn't know what. Because I had no money he would't look at it. So, what would the part be named (possibly part number too) that connects the belt assembly (crankshaft position sensor or the tensioner and timing belt?) to the crankshaft at the bottom of th engine. Thanks!

    "Harmonic balancer" is the pulley at the end of the crank but I don't think it will cause the knocking sound (unless it is loose).

    It is possible that one of the idler pulleys or the tensioner pulley is worn out and wobbling. Check under the hood with the engine idling and see if the pulleys turn straight. Good luck.
