Bolt that holds the rear passenger side axle in place has broken off. This was found during a tire rotation at the dealership.
BROKEN AXLE BOLT
Passenger side, rear wheel axle blot sheered off, been loose for ??? Was told not to drive the vehicle, safety issue. Seems to be a common problem with the Mac towing package.
Heard squealing in brakes and rattling in passenger rear area. Took to Ford service and they found loose bolt head and washer that was sheared. Recommended not to drive vehicle but could not confirm that it is a warranty issue at this time. Less than 24k miles on vehicle.
The rear axle bolts sheared off for unknown reasons. The symptom was a metallic rattling noise from the back of the vehicle - the noise was pieces of the axle bolts bouncing around inside the wheel center cap.

The rear axle bolts sheared off for unknown reasons. The symptom was a metallic rattling noise from the back of the vehicle - the noise was pieces of the axle bolts bouncing around inside the wheel center cap. The bolt in questions holds the rear axles in place. Vehicle has been at dealership for 2 weeks as they said it was a common problem that is a safety issue. Said it was possible for one or both of the rear wheels to fall off if I had continued driving it. Obviously losing one or two wheels is a huge safety concern. My dealer said he has seen this exact issue 4-5 times on similar trucks. Vehicle is less than 9 months old and has less than 13,000 miles on it. Vehicle is being repaired under warranty but using the same parts.
I took my truck in for it's first oil change and tire rotation. I was called by the dealer a few hours later and told that when they pulled my rear tire off, the rear rotor axle bolt was seared and the vehicle is unsafe to drive.

I took my truck in for it's first oil change and tire rotation. I was called by the dealer a few hours later and told that when they pulled my rear tire off, the rear rotor axle bolt was seared and the vehicle is unsafe to drive. As the tire had never been removed previously they said it had to come from the factory that way, and that I was lucky the tire did not fall off while driving the truck. I was told the parts would be ordered and repairs done under warranty but it's been over a week with no information or results. I researched the internet and found hundreds of owners experiencing the same issue with the rear axle bolt being seared, apparently at the factory. If this makes the vehicle unsafe for the road and it's obviously affecting 100's of vehicles that I can find in some internet search, the problem is likely much worse. I have the exact issue reported in this forum at https://www.f150forum.com/f129/2021-powerboost-rear-rotor-axle-bolt-sheared-515460/.
