Need help or suggestions where to turn.
I have new 2024 F150 XLT 302A Equipment Group, with 5.0L with only 1750 miles on it.
While in 2H, Normal mode, It started making a strange sound / vibration like something rubbing, last for about 30 seconds to a minute or so around 45 MPH and higher was at 62 mph the other day. Very Intermittent, and random. Just happens, highway, back road, slow speed and or highway speed. Its kind of hard to describe, sounds and feels almost like running over rumble strips. Kind of a humming, low whining type of sound. Like a hard piece of plastic rubbing or something and you can feel it. It just happens while driving, I'm not switching drive modes or anything, just driving straight in 2H Normal Driving Mode.
Took it to the dealer and of they could not replicate the noise/vibration, kind of the way it goes right.
But after talking to the service rep she found a Bulletin that identified what I was describing as the IWEs. The only difference was according to the bulletin this happened when switching to and from 4H to 4L, which wasn't what was happening to me. But they wanted to go ahead a replace them anyway, thinking it would solve the issue, So I agreed.
Anyway, they replaced them, pick up the truck yesterday and it did it on the way home from the dealer. I did call and left a message that it still doing it. Haven't heard anything back from them, don't really expect to as what are they supposed to do. Its getting frustrating at this point. Just not sure what to tell them or what to do. I keep trying to catch it on video, hopefully that may help. Just not that fast with a phone. I did however capture a few moments of it. I'll try and upload it to here. Tried Google not much help except getting me here. Just not sure what else to do at this point. I have to make a trip from eastern PA to Central Illinois and pull a trailer back. I have a brand new truck and afraid to use it, in fear of something bad happening.
Let me clarify that want was done at the dealer was per TSB24-2189. The replaced 2ea ML3Z*3C247*J Actuator Asy. Not sure if its the same as the IWEs or not. "Clean the splines and replace both front IWE Actuator Assemblies"
It did it again today at around 40mph. I was out hoping it would do it in the spot it happened before on the highway. It didn't, however it did happen on the way back at around 40mph. When i got off the highway I put it in 4H for about 2 miles, then back to 2H,very shortly otter that is when the noise happened lasted about 30 seconds or so, maybe half a mile. Was able to catch it briefly on video, and you can hear when it stops.
Yeah, so my truck doing the same thing 2023 f150 6k on it the first cold snap in Minnesota at about 19° outside last year it’s just like the rumble strip noise. I had that TSB done picked it up. Did the same thing again the next day brought it back to the dealer they called the Ford hotline. I have my work order noted on it and apparently Ford supposed to come out with updated IWE and possibly a software update. I stopped at the dealer last week just to see if there were any updates currently available but nothing as of yet this has been going on since December 2024. When it’s below 32° I’ll sometimes drive it around the block a few times to get the front differential warmed up and apparently that’s the problem. The IWE’s try to unlock once it gets warm keep bugging the dealer because there is an issue with them and it sounds just like the rumble strips just as you described.
My 2 trucks (platinum/23 and lariat/24) have a similar noise, when I put it in 4A and the front wheel drive engages, it stops immediately as in the video. Ford here (Brazil) doesn't know and had no complaints before this noise.
