  Problem

  KENWORTH IS RECALLING CERTAIN MODEL YEAR 2009 THROUGH 2010 T660 TRACTOR TRAILORS MANUFACTURED FROM JULY 1, 2008 THROUGH JULY 31, 2009.

THE FASTENERS ATTACHING THE STEERING GEAR TO THE FRONT DRIVE BRACKET MAY HAVE RECEIVED INSUFFICIENT TORQUE DURING THE INSTALLATION PROCESS RESULTING IN LESS THAN REQUIRED CLAMP LOAD.

  Risk
