Lug Nuts Loose 3x

In the past 8 months my lug nuts have been loose three times now. On my 2014 WK2 Laredo stock wheels and lug nuts. First two times was after dealer services vehicle and pretty much within a couple days where the wheel was shaking or I noticed he pigs backed out. The third time I took it in to have the trailer lights ecm flashed and a couple days later the wheel was shaking on the highway. They said they didn’t touch the wheel. I had the dealer evaluate it and they say it’s the rust between the wheel and he rotor and wanted 350 to sand it off. The I took it to a private mechanic shop. He said there is hardly any rust and that the lug nuts he found have an issue with them swelling. Also thought that the lug nuts had some play in them once threaded on the studs. Not sure where to go from here?! I Called dealer back and told him of the other mechanics findings and he disagreed.

Are you sure they are OEM lug nuts? The OEM studs are longer than the average, and many aftermarket lug nuts bottom out before being tight.

After any service the lug nuts need to be retorqued to spec after 50 miles.

Often times places will either not tell you this or people just don’t know it.

I have a 14 and have never had this issue with stock rims or other sets.

They are definitely stock wheels and lugs. What’s strange is after the second time I brought it home and torqued them myself which is why it’s odd they came loose about a month or so later. Has anyone heard of issues with the factory lug nuts? I hate to go throwing money at this.

You should try deep (longer) lug nuts as this is a classic symptom reported here often when the nuts are too short. They bottom out on the stud, get tight enough to the feel or torque wrench, and either twist and break or eventually work themselves loose. The nuts should be torqued to about 100+ pounds?

x2. Manufacturing being what it is (in China) some are out-of-spec or you'll get stack-up of micro tolerances in the same direction.

If you're worried about $$$, just go buy one or two longer ones...give it a go for a month.

You can also put a small blob of putty on the end of a stud with your regular nuts...tighten/take off/observe putty

I’ve read conflicting info on the torque spec.

One place I saw 110 ftlbs the other said 90 I’m sure either is plenty, I do around 100

If you follow the manuals over the years you find the torque spec started at 95 for early models and made its way up to 130 Ft-Lbs for 2018. I don't think technically there were any changes, so FCA may have learned something over the years.

Hello Jeep3265,

If you end up going back, be sure to send me a private message. I'd be glad to get you an additional layer of assistance who'll make sure all options have been explored during that appointment.

dismount a wheel and look closely at the holes...are they slightly worn oval shape? If so, loose lugnuts will do that kind of damage to the wheel--it only takes one time--- and it's likely they'll never stay tight again. Reason is conical taper against backside of lugnut is no longer precise as in a "wedgemate". Choice is replace the wheels or make checking lugnut torque part of your engine oil change maintenance schedule.

I had the opposite issue (this was over a year ago, at around 20k) - when I took my wife’s Jeep to the dealer for an oil change and tire rotation, they weren’t able to do the rotation because the lug nuts had “swollen” (their words... I had to Google “Jeep swollen nuts” after this, and felt all kinds of awkward) and were stuck on the studs. I did a search and on another forum (I don’t remember which one) and a number of Jeep owners did mention this was an issue. Had them replaced OEM (although Gorilla was a popular recommendation too), and so far, so good. Still, though, in 25 years of owning vehicles, I can’t remember ever having this issue before.

I always hate it when I get swollen nuts.

So this is or isn’t a common issue with the lug nuts? I am not sure the lug nuts will solve the problem. Or the rust removal which is hardly there. I feel like I’ll just be throwing money and this and still wondering if safe to drive. Time to trade it in??

Not common at all. The only time I've heard of it is when using aftermarket wheels and nuts or worn wheels due to forgetting to torque them down. Some aftermarket wheels have a hub centering ring, and if you put OEM wheels on without removing the rings you will get something like you describe.

What do you think would solve this problem? Why do you think its unsafe. Have you been checking the torque every day?
