Very Scary But Was It Preventable?

I was watching some videos this morning and came across this, picture taken from video…..
IMG_5731.jpeg

Truck is a 2017 Chevy Silverado with a reported 380,000 miles on the odometer.
Also reported the truck received regular maintenance including tire rotation, this happened roughly 100 miles following a rotation, front passenger side, driver reported hearing some noise and a minute later the wheel was gone.
My thoughts is serious over torque however I’m also wondering if the lugs should have been changed out due to torque stretching.
All 6 lugs at once, luckily no one hurt.
Opinions???
 
My thoughts are first that's a rigged picture. Been driving for a lot of years, worked on a lot of cars , and even worked in a body shop at a dealership never seen anything like that.

Second thought, if it's real, either they were as you noted seriously over tightened , or someone did it on purpose.
 
Those were seriously overtightened. A few years back i was behind a guy in a jacked up 1500 chevy and the driver side front wheel just came off. ole boy done a good job of getting it stopped without a crash cause we was goin at a pretty good clip.

My guess he had probably the same problem and also had way too much weight on a 1/2 ton front end. he had huge super swampers and huge rims on it. a lot of weight hangin on a 1500 spindle.

I will not discount your thoughts on this as I had the same however the video; which as I said the picture came from was an in-depth account by someone who came across as very knowledgeable and well spoken.
 
I have seen that happen but it wasn't due to over tightening. It was due to the lug nuts loosening. and it happened to me on my car. I have told about owning a 1973 mercury Comet that I , shall we say , modified.

I had mag wheels on the car that looked like Craigers but weren't. They were made to fit different bolt patterns by use of an adapter that fit in the bolt slot of the wheels. I had to check them every so often because they would loosen. No matter how often I torqued them to 100-110 LB FT. So one day I had my mom , my girlfriend , girlfriends brother and his wife all in the car going home from town.

I was running about 60 MPH and started around this sweeping curve on the highway when everything went South. All of a sudden the rear of the car launched and jumped sideways and started doing a very bad dance , jumping all over the place. I had my hands full staying in my lane but I finally got the car stopped . I got out looked at the car and saw nothing wrong. Walked all around the car and saw nothing. Of course I was puzzled and started a second trip around the car. Then it was like seeing something but the brain wasn't absorbing it.

There were 4 lug nuts and studs missing from the right rear wheel . When the car stopped the wheel aligned as it should be normally. the one lug nut still on the car was loose. I had to call my Brother - in - Law to bring me 5 studs and nuts so I could fix the car and the next day I went and bought a set of mags that were made to fit the car without the stupid adapters. I had been planning on doing this anyway.

So I said all this to say that it could have been an over sight in not tightening those lug nuts all the way after the tire rotation. By the way , I never felt any difference in the way the car acted up until it started doing the jumping around.
 
A friend of mine received just under 200k from a chain tire shop after his Bronco lost a wheel and caused a roll-over crash with his family inside. Had to employ an expert witness in metallurgy and the chain fought right up until the week of a jury trial. The cause was over tightening in his case.
 
The only problem like this i had was on a trailer. If you rotate excessively it can happen on high mileage vehicles. Usually not all at once though. Several tire shops in go to torque to manufacturer specs, but with a preloaded nut driver and not an actual torque wrench. I do a preload of all at half max after "snugging" up all in a criss cross pattern.
 
I have always changed my own oil. don't think i ever paid anyone to do it. my trucks are easy to get under. never need a jack. i also have fumoto oil valves on both ot them. also makes it easier. although the cummins oil filters are a bit of a pain to get to.
 
Just my two cents as well two comments ... 1st, being out of the mechanic business for many years, and having not done a lot of work on my own trucks in years, I wasn't aware there was a current "Silverado" with a full floater rear end. Is that true? And 2nd, as well that almost looks like an 8 lug hub where some pneumatic wrench jocky just hammered the lugs with his new air wrench and no regard for mfg's recommended torque during a tire rotation. I've seen more of that over the years than loose lugs causing them to shear, although it can happen from either circumstance. And unless I'm seeing things, isn't that 8 bolt axle cap only available on a 1 ton these days? I think I remember back in the <80's and maybe 90's there was a class of 3/4 HD that came with a full floater and 13" ring gear. But I thought that had ended some years ago.

Again, even though I'm a well satisfied Silverado 1500 owner/driver, I simply don't keep up with them like I used to. So I am curious. Thnx. jj

So, I can't believe I know more, or even as much about this than some of you reading it. Can't somebody tell me about the full locker in a late model Silverado? And it looking like a 1 ton due to the 8 bolt axle cap. C'mon some of you ol' shade tree mechanics, get a little grease under your nails and help me out here. Thnx, jj.
