2007 BMW F800 ST Suspension Problems

TL* THE CONTACT OWNS A 2007 BMW F800 ST. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 40 MPH, HE NOTICED A CHIRPING SOUND COMING FROM THE REAR. THE VEHICLE WAS TAKEN TO THE DEALER FOR DIAGNOSIS. THE TECHNICIAN STATED THE REAR WHEEL BEARING WOULD HAVE TO BE REPLACED AS WELL AS THE REAR AXLE SUSTAINED DAMAGE DUE TO THE REAR BEARING FAILURE. THE MANUFACTURER WAS NOT MADE AWARE OF FAILURE. THE VEHICLE WAS REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 18,000.

DURING USE LAST WEEKEND I NOTICED THE DRIVE BELT RIDING ABNORMALLY ON THE REAR DRIVE PULLEY. I DISASSEMBLED THE REAR DRIVE ON THE MOTORCYCLE TODAY AND FOUND THE BEARINGS AND REAR WHEEL SUPPORT SHAFT IN NEED OF COMPLETE REPLACEMENT. INVESTIGATION ON THE WEB READILY REVEALS DOZENS OF THREADS ON THIS SUBJECT, WITH RESULTS OF FAILURES INCLUDING COMPLETE WHEEL LOCKUP AT HIGHWAY SPEED. SIMPLY DO A SEARCH USING "BMW F800 BEARING FAILURE" AND PRIMARY RESULTS ENCOUNTERED WILL BE FOR THE REAR WHEEL BEARINGS - SEVERAL PAGES OF THEM. THE REAR SUPPORT AXLE WAS REDESIGNED WITH NEW SHIPMENTS IN MID 2009, HOWEVER, BMW DESIGNATES THIS AS AN "IMPROVEMENT" NOT A CORRECTION OF DEFECT. THESE FAILURES ARE ALMOST ALL ON PRE 2009 MODELS AND GENERALLY OCCUR AT LOW MILEAGE SUCH AS THIS MACHINE. FAILURE OF THIS COMPONENT CAN READILY CAUSE A COMPLETE LOCKUP OF THE REAR WHEEL AS REPORTED BY SEVERAL RIDERS, RESULTING...
