MAY 29, 2021 – VIN LIST – FSA 21S28 VIN LIST
Description
AFFECTED VEHICLES ARE BUILT WITH A STEERING GEAR BALL NUT RETAINER THAT MAY BE CRACKED. ADJUSTMENTS TO THE STEERING GEAR SUPPLIERS ASSEMBLY TOOLING ALLOWED INTERFERENCE WITH THE BALL NUT RETAINER DURING INSERTION OF A SNAP RING. THIS INTERFERENCE ALLOWED THE ASSEMBLY EQUIPMENT TO DAMAGE THE RETAINER.
Safety Risk
A BROKEN STEERING GEAR BALL NUT RETAINER CAN ALLOW BALLS IN THE BALL NUT ASSEMBLY TO DISPLACE AND WEDGE. CONTINUED STEERING WHEEL MOVEMENT CAN FURTHER WEDGE THE BALLS AND DISPLACE THE RETAINER, RESULTING IN INCREASED STEERING EFFORT. SHOULD THIS CONTINUE AND THE BALLS DO NOT TRANSITION BACK INTO THE RETURN GUIDES, THE BALL NUT MAY NOT BE ABLE TO ROTATE. AS A CONSEQUENCE, THE DRIVER MAY NOT BE ABLE TO ROTATE THE STEERING WHEEL WHILE DRIVING, INCREASING THE RISK OF A CRASH
Remedy
OWNERS WILL BE NOTIFIED AND INSTRUCTED TO NOT DRIVE THEIR VEHICLES. THEY WILL BE ASKED TO WORK WITH A FORD OR LINCOLN DEALER TO HAVE THE VEHICLES TOWED IN FOR SERVICE. DEALERS WILL REMOVE AND REPLACE THE STEERING GEAR FOLLOWING NORMAL WORKSHOP MANUAL PROCEDURES. THERE WILL BE NO CHARGE FOR THIS SERVICE.
