## Discrepancy

INBOARD WHEEL ASSY OF LT MLG  WAS MISSING.  RETAINING NUTS AND WASHERS STILL IN PLACE AND SAFETIED.  IB WHEEL BEARING WAS STILL ON AXLE, WITH NORMAL AMOUNT OF GREASE STILL ON IT.  OB BEARING WAS GONE EXCEPT FOR  INNER RING, BUT NO CAGE OR ROLLERS.  AXLE AND BRAKE ASSY INSPECTED OK.  OTHER MLG WHEELS WERE REMOVED, DISASSEMBLED, INSPECTED, AND REASSEMBLED WITH NEW TIRES INSTALLED.  OTHER WHEELS SHOWED NO SIGNS OF WEAR OR DAMAGE.  ALL BEARINGS WERE ADEQUATELY LUBRICATED, BUT DID REPLACE TWO BRGS AND CUPS DO TO NORMAL WEAR PATTERN.  INSPECTION SHOWED OUTER BRG DISINTEGRATED AND INN WHEEL HALF HAD MULTIPLE CRACKS RADIATING FROM BRAKE DISC KEYWAYS.
