I'm getting closer to heading to the bone yard and looking for a wrecked 21-22 so I can pull the assembly apart to see what we're up against.
That would be really appreciated!!!

Had my driver side rear axle bolt sheer off at 13800 miles. Requested the dealership service writer to check for wheel bearing play. When I went to pick up the truck after they replaced the bolt under warranty I had asked if they did that, they could not confirm that their tech did. I requested that they check that about 4 times, in person and over the phone.
They argued with me that the wheel bearing is ok because the screeching noise is gone. I work on cars for a living. I know the wheel bearing is bad. The axle bolt is just aligning the rotor back in position and relieving the screeching noise symptom. They’re arguing that they have 40 years of experience and they will not inspect it further unless I paid for it. They said since I didn’t buy the truck from them, they’re putting their customers first and they will not service my truck anymore. Service manger also made an assumption that I “took a wrench to it”. The wheel bearing is now making a clicking sound 8 miles since I picked up the truck.

Sounds like the disservice manager from the dealership I bought my truck from, who are a bunch of useless gaslighting dickweeds that will spend 200% of the effort of fixing the problem to make excuses for why they are not fixing it. I even have an email from a Ford regional tech explaining to them what they needed to do; yet the losers still couldn’t get their act together. I wound up having to take my truck an hour farther away to another place where they fixed it in less than 15 minutes!

You are better off not going there and just count yourself lucky that you’re not one of the mechanics that works with those clowns all day every day. I would have caused a scene if that dude accused me of ‘putting a wrench to’ the hub and told him that there was no need; because the only bolt holding it on had broken off and you don’t even need to take the wheel off for a cursory inspection of the wheel bearing.

Do some research and find another dealership and open a case with Ford. The SOP on the sheared axle bolt has been to replace the entire axle and hub assembly. I think mainly because of the excess axial play that results from the bolt shearing and then the only thing holding the wheel on is the brake caliper.


Good luck with your truck and sorry to hear about your shenanigans with the dealership!

At about 50,000 kms started to hear slight grinding, scraping noise from passenger side… pulled wheel and found the axle bolt broken. The pulled drivers side, bolt was intact and looked normal. Will let dealership know tomorrow.

Since this is a safety issue, owners with this failure need to file a complaint with the NHTSA.GOV. If NHTSA gets enough, they will require Ford to put out a recall notice.

So new developments in my sheared bolt story. I had the bolt extracted and replaced last week (or two two). Driving up north and I hear the same dragging brake screeching again. Pull over and pop the Ford logo plastic off, bolt is still there, put a 3/8 ratchet with the right socket on and probably put a 1/4 turn on it... Seemed to make it go away for a while, then it returned.

What is the torque supposed to be on this bolt? Seems like something I shouldn't be able to turn with side-of-the-road hand tools. Might need to lift it up and put some locktite blue on it and retorque when I get home? If it's at the spec it's supposed to be then back to the dealer it'll need to go.

If it were me, I might go with the red Loctite. I really only use the blue stuff on smaller fasteners and bicycle parts.
Would be red for me too, especially on a part where I can use a pencil torch to add high heat if/when it needs removing.

Took it to the dealer, it's been really wet the past couple days here and noticed it went away and told them they're probably going to not be able to duplicate it... and sure enough they weren't able to... We'll see what's the next play here.

If it returns again I'll remove, red locktite and and send it to 100ftlbs... this is a weird issue. We'll have a recall on this soon I'm sure
I believe the bolt is torque to yield and must/"should be" replaced every time. I used "should be" because most of us have re-used such a bolt but IMHO, for this location, it really needs to be new.
