## Discrepancy

AIRCRAFT WAS GROUNDED: DURING PUSHBACK - VERY ROUGH PUSH, VERY LOUD SOUND FROM THE NOSE DURING TAXI - ONLY DURING LEFT TAXI TURNS AND DURING BRAKING. MAINTENANCE CONFIRMED THAT WHEN TURNING THE NOSE LANDING GEAR TO THE LEFT AND TO THE RIGHT WITH THE WHEELS INSTALLED A GRINDING NOISE OCCURS. MAINTENANCE DISCONNECTED THE WHEELS AND THEY WERE ABLE TO TURN THE NOSE LANDING GEAR SLLEVE. MAINTENANCE DETERMINED THE INTERNAL PORTION OF THE GEAR WAS CAUSING THE ISSUE AND REPLACED THE NOSE LANDING GEAR LEG ASSEMBLY PER TASK CARD 26L71032003.
