PAINT ON THE WHEEL MOUNTING SURFACES CAN ACT AS A SHIM BETWEEN THE WHEEL AND THE ROTOR/DRUM. AS THE VEHICLE IS DRIVEN, THE WHEEL IMBEDS INTO THE PAINT, LOOSENING THE LUG NUT AND CAUSING A LOSS OF CLAMP LOAD.
ONCE CLAMP LOAD IS LOST, ALL TIRE LOADS ARE TAKEN BY THE WHEEL STUDS RESULTING IN A FRACTURE OF THE WHEEL STUDS. THIS COULD CAUSE THE WHEEL TO SEPARATE FROM THE VEHICLE AND COULD RESULT IN A VEHICLES CRASH WITHOUT PRIOR WARNING.
DEALERS WILL CLEAN THE WHEEL MOUNTING SURFACES FOR ALL FOUR WHEELS. ALSO, THE WHEEL STUDS WILL BE INSPECTED FOR DAMAGE AND WILL BE REPLACED AS NECESSARY.
SYSTEM: WHEELS; LUG NUTS; BOLTS.VEHICLE DESCRIPTION: PASSENGER CARS.
