Factory part number 4L3Z-4320-BA: a nut locking supplied by FORD.
It is catalogued under Nuts & Washers > Nuts.
Nylon-insert lock nuts lose their prevailing torque after a single removal and should be replaced rather than reused. The number stamped on the old part is the only reliable identifier, since two parts can look identical and differ by a millimetre or by rotation direction.
Ships from our US warehouse in one to two business days, free over $59. Check the number on the part you are removing before ordering. If it is worn off, send the VIN and a photo and we will match it.
