The defect
THE BOLTS AND NUTS WHICH ATTACH THE BEARING-HUB ASSEMBLY TO THE REAR AXLE FLANGE ARE NOT SUFFICIENTLY TIGHTENED ON SOME VEHICLES.
The risk
THIS WOULD ALLOW EXCESSIVE MOVEMENT OF THE BEARING-HUBASSEMBLY RELATIVE TO THE REAR AXLE FLANGE AND COULD CAUSE ELONGATION ANDEVENTUAL SEPARATION OF THE ATTACHING BOLTS FROM THE REAR AXLE FLANGE. IF THISWERE TO OCCUR WHILE THE VEHICLE WAS IN MOTION, THE AFFECTED TIRE AND WHEEL COULDTRACK ERRATICALLY, EVENTUALLY CAUSING FAILURE OF THE OTHER ATTACHING BOLTS. THETIRE AND WHEEL ASSEMBLY COULD SEPARATE FROM THE VEHICLE WHICH COULD RESULT IN AVEHICLE ACCIDENT.
The remedy
TIGHTEN REAR AXLE BEARING-HUB ASSEMBLY FASTENERS, AND REPLACE ALL THE FASTENERS ON A WHEEL IF TWO OR MORE BOLTS ARE FOUND TO BE LOOSE.
