Paccar Incorporated: Trailer Hitches › Fifth Wheel Assembly
Paccar Incorporated reported this defect to federal regulators on Nov 30, 2006 and put the number of vehicles at risk at 86. The repair is free for as long as the recall stands.
The defect
ON CERTAIN TRUCKS, AN RA529 KING PIN RELEASE AIR VALVE WAS MANUFACTURED WITH THE INTERNAL SPOOL INSTALLED BACKWARDS. THIS RESULTS IN THE AIR OPTION OF THE KING PIN RELEASE SYSTEM BEING INOPERABLE. TO CORRECT THIS SITUATION, THE VEHICLE'S AIR LINES WERE REVERSED RATHER THAN REPLACING THE VALVE.

The remedy
KENWORTH WILL INSPECT THE KING PIN RELEASE SYSTEM AND SUSPECT VALVE. IF ANY VEHICLES HAVE A NONCONFORMING VALVE OR INCORRECT PLUMBING, IT WILL BE REPLACED AND RE-PLUMBED. THE RECALL BEGAN ON NOVEMBER 29, 2006. OWNERS MAY CONTACT KENWORTH AT 1-425-828-5440.

What this page is, and what to do next
A recall is not an opinion. It is a Part 573 report a manufacturer is required by federal law to file once it decides a defect poses an unreasonable risk to safety, and it commits them to repairing the vehicle at no cost to the owner. The three passages above are the manufacturer’s own wording as published by NHTSA.
This page describes the campaign. It cannot tell you whether one particular car has already been through the shop — that is tracked by VIN, and only the manufacturer knows it. Check yours at nhtsa.gov/recalls or with a franchised dealer, quoting campaign number 06V461000.
