What this recall covers

NHTSA's campaign record, quoted as published

The defect

IT HAS BEEN DETERMINED THAT TWO SCREWS THAT ARE PART OF THE BEARING ASSEMBLY LOCATED AT THE CAB DASH SHEET MAY NOT HAVE BEEN TIGHTENED PROPERLY. AS A RESULT, THE UPPER STEERING SHAFT MAY BE FREE TO "FLOAT" THROUGHOUT MUCH OF ITS LENGTH WHICH MAY RESULT IN INADEQUATE ENGAGEMENT IN THE SLIP SPLINES OF THE LOWER STEERING SHAFT. AXLE ARTICULATION COULD RESULT IN DISENGAGEMENT OF THE LOWER STEERING SHAFT SLIP SPLINES.

The remedy

DEALER WILL INSTALL A SLEEVE BETWEEN THE DASH SHEET BEARING AND THE UPPER STEERING SHAFT LOWER YOKE TO ASSURE POSITIVE UPPER STEERING SHAFT LOCATION.

Notes

VEHICLE DESCRIPTION: TRUCKS.SYSTEM: STEERING ASSEMBLY; STEERING COLUMN SHAFT, UPPER.CONSEQUENCES OF DEFECT: LOSS OF STEERING CONTROL COULD CAUSE LOSS OF VEHICLECONTROL AND AN ACCIDENT.

A safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.
