Short answer is I put nothing on wheel lugs or lug nuts. I just make sure every thing is properly tight.
I'm driving my first RV so I do not know if all work the same was. Hear goes.
The simulator is held on by a nut that threads over a very short connecting nut that threads onto the lug stud outside the lug nut that holds the wheel. My RV came with a special "T" handled wrench for the chrome cap nut, and an alan wrench for the conecting nut.
When removing the simulator the connecting nut almost always comes off with the cap nut. I always remove the connecting nut (with the allen wrench) from cap nut and put the connecting nuts (two per wheel) on the wheel studs with as much force as I can put on the alan wrench. The Alan wrench is to short to over torque the nut or bolt.
With the connecting nuts on i mount the simulator on the wheel waing the provided wrench.
If the connecting nut is left inside the cap nut when mounting the simulator I believe you can't get the assembly as smug.
