## Discrepancy

AIR RETURN DUE TO VIBRATION FELT INFLIGHT.  INSPECTED ALL COMMON AREAS ON AIRCRAFT THAT CAUSE VIBRATION.  FOUND NOTHING THAT COULD VIBRATE.  AFTER REMOVING LT SPINNER FOUND ROUGHLY A 1/4 POUND OF GREASE BUILT UP ON ONE SIDE OF SPINNER.  ALSO FOUND ONE DE-ICE LEAD BROKEN AND SUSPECT ICING BUILD UP THAT THREW PROP OUT OF BALANCE.  INSPECT LT AND RT PROP HUBS FOR OIL.
