## Discrepancy

VIBRATION AT 156KTS AT THE POINT OF NOSE STRUT EXTENSION CONTINUED TILL NOSE WHEEL FULLY RETRACTED. SOMETHING IS LOOSE IN THE NOSE GEAR ASSYMBLY.  FOUND NLG DOOR ASSY AS SUSPECTED CAUSE OF VIBRATION DUE TO EXCESS FREEPLAY. FOUND HARDWARE ON LINK ASSY TO DOOR AND HARDWARE FROM LOWER FITTING ASSY TO GEAR LEG WORN. R/R'D HARDWARE AS REQUIRED PER AMM 32-22-15. NO FREEPLAY NOTED AFTER HARDWARE CHANGE. OK FOR SERVICE.
