## Discrepancy

DURING LANDING ROLL OUT,  CREW FELT A VIBRATION IN THE NOSE GEAR SIMILAR TO A FLAT TIRE.    MAINTENANCE INSPECTED ACFT AND FOUND THE RT NLG WHEEL ASSY BEARING ON AXLE NUT SIDE OF THE WHEEL ASSY HAD FAILED.  A TEMPORARY RT NLG WHEEL ASSY WAS INSTALLED. FURTHER INSPECTION FOUND AXLE GOUGED BEYOND LIMITS. NLG LOWER INNER CYLINDER AND SEALS, AND THE NLG RIGHT AXLE NUT, ALONG WITH THE TEMPORARY RIGHT NLG WHEEL ASSY AND THE LT NLG WHEEL ASSY WERE REPLACED.
