ARVINMERITOR IS RECALLING CERTAIN REPLACEMENT WHEEL STUDS WITH PART NO. NC-11 MANUFACTURED BETWEEN APRIL 7 AND MAY 19, 2008. THESE WHEEL STUDS WERE ALSO ASSEMBLED INTO TRAILER AXLE HUBS AND SOLD TO VARIOUS VEHICLE MANUFACTURERS FOR USE ON HEAVY TRUCKS. THE SUSPECT WHEEL END STUDS WERE IMPROPERLY TEMPERED, POTENTIALLY RENDERING THEM BRITTLE AND SUSCEPTIBLE TO FRACTURE. IF ONE WHEEL STUD FRACTURES, THE REMAINING WHEEL STUDS ARE REQUIRED TO CARRY MORE LOAD. IF LEFT IN THIS CONDITION, THE REMAINING WHEEL STUDS MAY ALSO FRACTURE EVEN IF THEY ARE PROPERLY MANUFACTURED.
