I AM A MAINTENANCE MECHANIC FOR A LARGE TRUCKING FIRM. ON 4 OCT 2011, I CHECKED THE TORQUE ON THE 5TH WHEEL BOLTS OF UNIT 11054 BECAUSE I COULD SEE THAT THE 5TH WHEEL WAS SLIDING ON THE FRAME. THE BOLTS WERE DEFECTIVE - YIELDING PRIOR TO REACHING THE RECOMMENDED TORQUE OF 236 FT.LB. I ADJUSTED THE TORQUE WRENCH TO 200 FT.LB., ITS LOWEST SETTING, AND COULD NOT GET ANY OF THE BOLTS TO HOLD. I REPLACED ALL TEN BOLTS WITH 5/8" GRADE 8 HARDWARE INSTEAD OF THE FACTORY 16MM 10.9 METRIC BECAUSE THAT WAS ALL WE HAD AVAILABLE. THERE WAS NO INTERFERENCE BETWEEN THE 5TH WHEEL BOLTS AND THE HUCK RIVETS ON THE FRAME RAIL. THE BOLTS WERE WEAK. *TR

Reading this record

No unusual pattern of severe incidents in the complaint record.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Most recent recall on file: none. Source: NHTSA Office of Defects Investigation.
