## Discrepancy

(CAN) DRIVE SHAFT WAS RECENTLY INSPECTED, GREASED AS REQUIRED AT MFG.   OLD BOOTS WERE SERVICEABLE, BUT AGE WAS NOT KNOWN SO REPLACEMENT WAS ELECTED AS A SAFETY PRECAUTION.  NEW BOOTS INSTALLED AND DRIVE SHAFT SERVICED.   21.1 HOURS AFTER REPACK GREASE LEAK WAS DETECTED BY PILOT AND DRIVE SHAFT REMOVED.   AS A SERVICEABLE DRIVE SHAFT WAS AVAILABLE THE LEAKING ONE IN QUESTION WAS (RED TAGGED).  UNSERVICEABLE DRIVE SHAFT DISASSEMBLED AND BOOT FOUND DETERIORATED, ALMOST TO A DISSOLVED STATE, RUBBER SEEMS MORE LIKE A PLASMA THEN RUBBER STATE.  BOOT INFO SKF BO201 SKF BCO-BO-7206 MFG 1/19/07.
