I switched it to 4A earlier and it indeed vanished. Scheduled next available Appt at dealer for Friday morning. Let’s see how much nonsense they throw my way regarding the warranty although I’m thinking it’s covered up to 60k miles. Sure the stealership will be pleased to learn they need to fix this under warranty AND the driver airbag cover that has torn for a second time under safety restraint warranty as well. I will console them by paying for my full synthetic oil change lol thanks for the input. Every time I go to Ford for service I feel like I’m about to plead my case to a Supreme Court.When you get a chance, put it in 4hi or 4A and see if it goes away. It should. Only issue is if the iwe or hub has been chewed up it won’t engage properly.
