Technical Service Bulletin TSB 16-001 — 2016 MERCEDES-BENZ SPRINTER 3500

IN 2016, MERCEDES-BENZ RELEASED A NEW 2-PC FLANGE NUT WHEEL FASTENER (MERCEDES-BENZ P/N A 000 990 53 53) WHICH IS TALLER AND HAS A LARGER WASHER DIAMETER THAN THE PREVIOUS 2-PC FLANGE NUT (MERCEDES-BENZ P/N A 000 401 18 72) USED FOR MODEL YEARS 2007-2015. DUE TO THE CHANGE IN HEIGHT OF THE 2-PC FLANGE NUT, ALCOA WHEEL P/N 25080X CANNOT BE USED IN BOTH THE OUTER REAR DUAL POSITION AND INNER REAR DUAL POSITION WITH THE NEW 2-PC FLANGE NUT AS THIS CREATES A SUB-FLUSH THREAD ENGAGEMENT CONDITION. IT IS RECOMMENDED THAT 2-PC FLANGE NUTS ARE AT LEAST FLUSH WITH THE END OF THE STUD. THIS COMMUNICATION EXPLAINS HOW ONLY ONE ALCOA WHEEL (P/N 25080X) MAY BE USED IN THE DUAL CONFIGURATION TO PROVIDE ADEQUATE THREAD ENGAGEMENT AND FASTENING OF OUR WHEEL.
