## Discrepancy

ON GEAR RETRACTION AS THE NLG ENTERED THE MLG WW COCKPIT CREW FELT & HEARD THE SPIN DOWN OF NOSE WHEEL THE TIME FRAME APPROXIMATELY A MINUTE.  IT WAS MUCH LOUDER THEN NORMAL & COULD FEEL EXCESSIVE VIBRATION  THROUGH PEDALS.  THIS IS A REPEAT WRITE UP.  AFTER PERFORMING THE TPC & NOTING NOSE TIRES WERE BOTH AT 163 PSI, AXLE JACKED NLG IAW MM 7-10- 07. PERFORMED A GVI OF NOSE WHEELS WITH NO OBVIOUS DEFECTS NOTED. PERFORMED REQUESTED SPIN-DOWN TEST  OF BOTH WHEELS.  REMOVED SUSPECTED FAULTY NR 1 NOSE WHEEL ASSY IAW MM 32-42-01. REMOVED SUSPECTED FAULTY NR 2 NOSE WHEEL ASSY IAW MM 32-42-01. DURING REMOVAL OF WHEELS, TECHS NOTED THE BREAK-AWAY TORQUES WERE 140 INCH IBS FOR THE NR 1 WHEEL, & 180 INCH LBS FOR THE NR 2 WHEEL. INSPECTED BEARINGS & NOTED GREASE APPEARED NORMAL IN COLOR & A SUFFICIENT AMOUNT PRESENT. CLEANED BEARINGS, BEARING SEALS, WHEELS, & AXLES WITH ONE DISCREPANCY NOTED; ONE GREASE SEAL, INBD SIDE NR 2 WHEEL, HAD A SMALL CUT.  PER MCC, THE LAST EVENT INVOLVED A RETORQUE AND WERE ADVISED THE BREAK-AWAY TORQUE AT THAT TIME WAS FOUND AT 500 INCH LBS FOR ONE OF THE WHEELS. THIS MAY HAVE DAMAGED THE WHEEL. PLEASE REPLACE THE WHEELS AT THIS TIME.  INSTALLED A REPAIRED NOSE WHEEL ASSY WITH TWO NEW BEARING SEALS, THE NR 1 POSITION IAW MM 32-42-01. INSTALLED AN OVERHAULED NOSE WHEEL ASSY WITH TWO NEW BEARING SEALS IN NR 2 POSITION IAW MM 32-42-01. VERIFIED A NORMAL SPIN DOWN OF BOTH WHEELS THAT WAS EQUAL WITH BOTH WHEELS. NO FURTHER ACTION IS REQUIRED.
