WHILE ON A CROSS COUNTRY MOTORCYCLE TRIP. I WAS TRAVELING AT HIGHWAY SPEEDS WHEN THE MOTORCYCLE BEGAN TO HAVE A GRINDING NOISE AND VIBRATION FROM THE REAR. I STOPPED TO FIND OIL LEAKING FROM THE FINAL DRIVE ALL OVER THE REAR TIRE AND WHEEL ASSEMBLY. WHILE ATTEMPTING TO STOP, THE REAR ABS SYSTEM ACTIVATED BECAUSE THE GEAR OIL SATURATED THE BRAKE ROTOR AND PADS. I ALMOST CRASHED THE MOTORCYCLE BECAUSE OF THE OIL ON THE TIRE. THE FINAL DRIVE WAS SERVICED PER BMW SPECIFICATIONS OF GEAR OILTYPE AND WEIGHT DAYS PRIOR TO THE TRIP. THERE WERE NO INDICATORS PRIOR TO THE FINAL DRIVE FAILING. THE GEAR OIL ESCAPED THE HOUSING DUE TO A TORN BEARING SEAL ON THE BACK SIDE OF THE HOUSING NEXT TO THE BRAKE ROTOR. TEARDOWN OF THE FINALDRIVE ASSEMBLY FOUND A DISINTEGRATION OF THE MAIN BEARING INCLUDING BALL BEARINGS. THE METAL IN THE HOUSING TEARING THE BEARING SEAL LEAKING OIL ON TO THE REAR WHEEL ASSEMBLY. THE METAL IN THE HOUSING ALSO DAMAGED THE SECOND SMALLER BEARING WHICH HAD TO BE REPLACED.
