loose lug nuts

[chevyltz3500]

I have a 2018 k3500LTZ with aluminum factory wheels.  18 inch tires.   The lug nuts loosen up after a tire rotation and I am have retorque the nuts about every 100 miles. They are torqued to 140 ft lbs.  The Chevrolet dealer says they have 11 K3500's doing this.  They do not have a fix.  The have recommended getting new wheels.   All the trucks that are having an issue have the same factory polished aluminum wheel.  GM part number 84397983.

 

I am wondering if any one else is having this issue ?   I have 3 duramax trucks, 2009, 2018 and a 2022.   The 2018 is the only one with a problem so far.

 

Can anyone recommend an aftermarket 18 inch wheel ?

Man, I would report that to the IIHS. Sounds like a major safety concern and buying aftermarket rims shouldn't be the solution.

I agree, this is a serious issue.

maybe make sure both the hub and the rim surfaces are flat and corrosion free?

 

I know for both my '04 and '12 3500, which are both duallies, I've had the rear wheel lugs loosen sometimes, after tightening, then driving a bit and then re-torquing them.  The fronts also sometimes, but much less common vs the rears.

 

And if you have the flanged flat face (vs the acorn style) lug nuts, make sure the flange part can spin easily.  I spray some fluid film on the outside and work it into the groove until the flange can spin easily, making sure not to get FF on the threads.  This seems to have helped with the lugs getting properly torqued, so they stay tight.
