2010 MACK CXU612 — Problems, Recalls & Safety Data

THE 5TH WHEEL MOUNT BOLTS ON MY COMPANY'S 2010 AND 2009 MACK TRUCKS ARE STRETCHING AND BECOMING LOOSE. I SAW UNIT 10101 ON SUNDAY, 20 MARCH 2011 ON OUR YARD READY TO HOOK UP. I HAD FINISHED MY SHIFT AND WAS WALKING PAST THE UNIT WHEN I REACHED OUT AND TURNED THE BOLT BY HAND. *TR

I AM A MECHANIC FOR A LARGE TRUCKING FIRM. I HAVE BEEN COMPLAINING ABOUT THE 5TH WHEEL BOLTS ON OUR 2008, 2009, AND 2010 MACK TRUCKS FOR TWO YEARS NOW. THE COMPANY HAS YET TO IMPLEMENT A PROGRAM TO CORRECT THIS MATTER, INSTEAD CHOOSING TO THREATEN ME WITH DISCIPLINARY ACTION FOR POINTING OUT LOOSE BOLTS ON OUR ROAD TRACTORS. TODAY (03/15/2011) I PASSED A 2010 TRACTOR ON THE READY LINE. IT WAS UNIT #10289 WITH ONLY 76327 MILES ON IT. THE 5TH WHEEL PLATE HAD BEEN SHIFTING ON THE FRAME AND ALL OF THE FASTENING BOLTS WERE RUSTY. THE TWO BOLTS THAT I CHECKED TURNED EASILY BY HAND - RATTLING LOOSE. THE BOLTS WERE NOT HITTING ANY THING THAT MIGHT HAVE LOOSENED THEM, THEY HAD STRETCHED. THE SHOP FOREMAN ON DUTY WAS THE ONE WHO HAD TOLD ME THAT I WAS "OUT OF LINE" TO LOOK AT TRUCKS THAT I DID NOT HAVE A WORK ORDER ON, SO I DID NOT RISK TELLING HIM. THE HEAD OF OUR SAFETY DEPARTMENT AT THE GENERAL OFFICE HAD TOLD ME THAT "THE COMPANY IS HANDLING IT AND FOR ME TO LEAVE IT ALONE" SO I AM REPORTING IT TO THE ODI. THE 5TH WHEEL BOLTS ARE LOOSE. *TR

MACK HAS BEEN SELLING OVER THE ROAD TRUCKS WITH SUBSTANDARD BOLTS HOLDING THE 5TH WHEEL TO THE FRAME. AS A MECHANIC WITH ABF, I AM SEEING TRUCKS EVERY DAY WITH 5TH WHEELS THAT ARE LOOSE. ON 22 SEPTEMBER 2010, I WORKED ON UNIT #10222 AT THE LITTLE ROCK SHOP. THIS TRUCK HAD ONLY 4376 MILES ON IT AND I COULD TURN THE 5TH WHEEL BOLTS WITH ONE HAND USING A 10 INCH COMBINATION WRENCH. I TRIED TO TORQUE THE BOLTS TO SPECS, BUT THEY ONLY STRETCHED. I REPLACED THE BOLTS WITH AFTERMARKET BOLTS WHICH TIGHTENED NORMALLY. *TR

AS A MECHANIC CONTRACTED TO MAINTAIN ABF ROAD TRACTORS, I WORKED ON UNIT 10064 ON 9/22/2010. I DISCOVERED THAT THE 5TH WHEEL MOUNT BOLTS WERE ALL LOOSE. THIS TRUCK HAD ONLY 51,285 MILES OF SERVICE PULLING PUP TRAILERS! I REMOVED THE BOLTS TO MAKE SURE THERE WAS NO THREAD DAMAGE, LIGHTLY OILED THEM, AND ATTEMPTED TO TORQUE THEM TO MACK SPECS OF 235 FT.LBS. TORQUE. NONE OF THE BOLTS WOULD TIGHTEN PROPERLY, ALL OF THEM STRETCHED. I REPLACED ALL OF THE BOLTS AND TAGGED THE DEFECTIVE BOLTS FOR MACK WARRANTY. AS A CITIZEN WHO EXPECTS THE HIGHWAYS OF THE UNITED STATES TO BE SAFE FOR TRAVEL, I AM ASKING THE ODI TO FIND OUT WHY ALL OF THE MACKS DELIVERED TO ABF HAVE DEFECTIVE 5TH WHEEL MOUNT BOLTS AND TO FIND OUT IF THE MACKS DELIVERED TO MORE DEMANDING CUSTOMERS ( SUCH AS LOGGERS, GRAVEL TRUCKS, CONCRETE TRUCKS, AND TANDEM AXLE FULL TRAILER LOAD TRUCKERS ) ARE ALSO ASSEMBLED WITH INFERIOR QUALITY FASTENERS THAT FAIL PREMATURELY. *TR
