Over tightened lug nut!!!

[Daren Todd]

Here's a classic example of what happens when lug nut's are hammered on with an impact till they won't move any more. Instead of tightening to the proper torque spec. Person noticed a wobble after installing a trailer tire. Pulled there impact out and hit the lug nut's a second time with out checking the rim or studs Hammered it a third time, then said screw it and went down the road. Tire came off as they were turning onto an on ramp for the interstate. It's always fun swapping out an axle on the side of the interstate



Fyi, the trailer must have been bouncing all over the place before the tire came off

OMG!

That kinda looks to me like it was loose for a long time. That ain't a cheap axle, either. I had one break on my landscape trailer, last year, it was a fatigue crack on the axle end. I also found, on dis-assembly that the suspension bolt bushings were wore out, in the transfer bar. That might have caused the fatigue. All told it cost me more than a grand, + the tow fee back to home...

I have seen similar-wheel wasnt seated and wobbled. All the torque in the world wont fix it. Wheel must be seated on hub and nuts tightened evenly as darren said to torque. Aluminnium wheels,be certain there is no corrosion on mounting surface.wheel will never torque correctly and nuts WILL loosen.
I could guess at what wheel nut torques should be,best to check with manufacturer.
Just checked my pictures, dont have an example of corroded wheel. As a matter of fact, i have a truck in the shop tomorrow with improperly tightened wheels,including stretched and destroyed studs. I torque every wheel i remove.

Why change the whole axle, wouldn't it have been cheaper and faster to change the hub? That is the part that is bad.

Also looks like it was the wrong size wheel for the hub, betting it was the wrong spacing and someone made it fit!

Driver clipped a concrete construction barricade when he was moving it off the road. Shaft ended up with a warp to it. It was the right rim and axle set up. Rim wasn't altered. Just the nut case going crazy with an impact I've come across it a couple of times on that style rim where the lug nut will eat into the rim if it's extremely over torqued. Usually it's only one or two that you'll find when changing out a tire. Then the stud, lug nut and rim get changed out. This happened to be an extreme case, where the person installing the tire got completely crazy. Not sure how long they were running around on it like that. Dropped off the tires to them a month ago.

Gotcha, Yes slamming them into concrete doesn't do them any good!

Could have been disastrous in traffic!

The OL took her Durango to Sears for tires, and a couple weeks later she comes out and a tire is flat, OK no problem I got the lug wrench out and tired to give the lug nuts a little twist to loosen them. IT AINT HAPPENIN,, Hummm ok get the air gun out,, NADA,, WTF ,, Long story short I called a bud who is a pretty fair old school mechanic. He looked and said they are all cross threaded, no way,, WAY,, had to use a nut buster to get the nuts off. Went to Sears and complained,, well someone must have done something to those wheel nuts after we put them on,,,, yeah right ,, Anyway after the OL pointed out the guy that did the tires and I watched him for a bit,, yep he hammered the snot out of them and it didn't mater how long it took. After a long drawn out discussion they agreed to replace all the lug bolts and nuts and paid for it to be done at the Dodge dealer. Yeah guys with airguns need to know what they are doing

That's what it looks like to me too.

Daren, when I read the title and your name I thought you must be upset with me over the email I sent last week!!

Nope not upset I could be considered one of those too!! figure I would point out the dangers of over tightening tires. Yesterday provided a good photo op Got some more photos to upload in a bit

Amen.
I had taken a '95 Tacoma in to a national tire chain for a new set of shoes, and I was watching through the window in the waiting room when they began mounting the wheels. This potatohead started the lug nuts by hand, picked up the impact, and proceeded to snap off the first stud. I headed for the door to the shop as he snapped off number two. I was stopped from entering the shop by a manager, (insurance regs) & by the time I explained the problem & pushed past him, Mr potatohead had snapped off all six. How stupid can you be, starch-for-brains? The manager said he would give me a PO to get the studs replaced at the Toyota dealer down the street, just take it down there. I had to explain to Mr potatohead #2 that that would be kinda hard with only three wheels. They grudgingly called a tow truck and I got it fixed, but some people are just too stupid to live.

I had an f550 service truck that was dropped at a shop we contracted with for the annual DOT inspection. Dropped the truck off and picked it up when they were done. Bear in mind this truck weighed 18.5k lbs. Checked the torque of the tires and everything seemed good when I did the pretrip inspection. Put around 150 miles on the truck that afternoon and had double checked the torque on the tires after driving 50 miles. Got up the next morning, did the pretrip again. Checked the torque for a third time. Left my neighborhood and noticed a shimmy in the rear end while turning Pulled off into a lighted parking lot, and checked the tires a fourth time. All of the checks were with a torque wrench. Inspected the tires closely, checking to see if there was any seperation starting. Pushed and pulled the tires as well to see if maybe a wheel bearing was fixing to go.

Jumped onto a toll road, drove 10 miles, was in the center lane fixing to merge west bound onto another toll road. Road was three lanes wide, center lane was for either west or east bound. Doing about 55 to 60 mph and felt the back end dip like you had a flat tire. Checked the mirror and didn't see anything looked back up in time to see one of my tires merging west bound
Guy had over torqued all the lug nuts on the truck and stretched every stud on the back end. His company ended up having to pay for a tow, 4 rims since he did it to both sides on the back, passenger side hub and brakes. Total bill was 5k. And a fresh pair of britches for me we found the tire a mile down the road with out doing any damage to another vehicle.

ACK!!!

ACK!!!

Here's a pick of a good rim. And a couple of one that was over torqued. Torque specs on that rim and axle set up are 100 lbs/ft torque. It took a two foot breaker bar and my 225 lbs standing on it to break the lug nuts loose.

The definition of insanity:
Doing the same thing over and over again expecting a different result!

When i was lead hand in a shop, impact my be used to run up nuts, but must be hand torqued with wrench. Guys didnt like it, but managment supported me.

Over done with impact, didnt have a clue how to get it off.
