THE TIE ROD USED ON THE DANA FA-64 FRONT DRIVE AXLE HAS A THREADED SLEEVE TO PERMIT TOE-IN ADJUSTMENT WITHOUT REMOVING AN END. THE TIE ROD BAR IS NECKED DOWN TO INCORPORATE THE SLEEVE. A STRESS RISER IS CREATED AT THE THREADED PORTION OF THE ADJUSTMENT SLEEVE WHICH MAY CAUSE A FATIGUE FRACTURE AND FAILURE OF THE TIE ROD WHERE IT SCREWS INTO THE SLEEVE.

Consequence

FAILURE OF THE TIE ROD ON THE FRONT AXLE RESULTS IN LOSSOF STEERING CONTROL AND A POSSIBLE VEHICLE CRASH.
