Defect: ON CERTAIN TRUCKS AND TRUCK-TRACTORS EQUIPPED WITH TRW DRAG LINK ASSEMBLIES, THE REPLACEMENT CLAMP AND DRAG LINK ASSEMBLIES CONTAIN A POTENTIALLY DEFECTIVE 5/8-11-GRADE B PREVAILING TORQUE HEX NUT. IF THE FINAL TIGHTENING IS LESS THAN 65 LB.-FT., THE CLAMP LOAD WOULD BE UNACCEPTABLY LOW AND COULD COMPROMISE THE INTEGRITY OF THE DRAG LINK.
Consequence: THIS COULD RESULT IN THE BALL SOCKET SEPARATING AND CAUSE LOSS OF STEERING CONTROL, INCREASING THE RISK OF PERSONAL INJURY OR A CRASH.
Remedy: DEALERS WILL REPLACE THE AFFECTED HEX NUT(S). OWNER NOTIFICATION BEGAN ON MAY 21, 2004. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT FREIGHTLINER AT 1-800-547-0712.

Notes on this record
Complaints from the API and bulk file are merged and deduplicated by ODI number; the API alone misses records.
System and subsystem counts are numbers of distinct complaints, recalls or communications that name them. One record can name several systems, so shares across systems can add to more than 100 percent; a single share never exceeds 100 percent.
Recalls are counted once per campaign, investigations once per action and manufacturer communications once per NHTSA id, even when NHTSA lists several model names for the same record.
A sales denominator is a calendar-year proxy, not the population of vehicles still in use. Rates are copied from verified pipeline output.
NHTSA's complaints API and bulk file list no complaint for this make, model and model year in this data build.
