After a recent brake change I, like many other Ford owners, have realized that stock nuts are junk and a big problem when you have a flat open road. During the replacement it took me over an hour to remove one of the factory nuts. They fit together perfectly and the one piece construction gave me confidence! Ford should pay people like me to replace these bad nuts. One more thing. The price for new nuts was excellent. Ford wanted $170 for a set of 24 full nuts.
