## Discrepancy

ABORTED TAKEOFF AT 75 KIAS DUE TO A SEVERE NOSE WHEEL SHIMMY THAT STARTED AT 50 KIAS.  SHIMMY WAS SO SEVERE THAT LOWER YAW DAMPER WAS KNOCKED OFF.  ALL INSTRUMENT PANELS WERE VIBRATING.  WHEN BRAKES APPLIED SHIMMY DID NOT GO AWAY UNTIL WE GOT TO ABOUT 30 KIAS.  REMOVED AND REPLACED LT/RT NOSE WHEEL ASSY'S IAW MM 32-41-01.  ALSO REMOVED AND REPLACED NOSE LANDING GEAR UPPER AND LOWER TORQUE LINK'S, OPERATIONALLY CHECK'S GOOD.  IAW CE750 M/M 32-20-00.
