Has anyone had problems with simulator nut particulary on your rear duals and is there a fix?

?? what the simulator nut/s? I assume your talking about the plastic ones in the stock center caps??
What sort of problem you have?? what kind of truck? My riding mower has 4 sim--- nuts on each wheel, they are the chrome covers..

It would really be of help to post what truck, what problem, and any other information to help get your answers.
()()( if it is the gm center caps and assuming your problem is they are stripped? I would just buy new parts for them, or you could wedge something in there as you screw it on, again this is assuming thats your problem?)()()

When I orderd my simulators, the dealer told me that they would come with extended nuts. When they got here, the nuts were the same length as stock. Could only reach about 1 to 1-1/2 threads on the studs. Went to the dealer and he called the supplier. Answer was to get one started, even one turn, then the next, then the next, etc. Do not use the cross pattern used for tightening the lug nuts, but one turn per nut one at a time, next to each other in a circular pattern. After about five times around, the center of the simulator will be sucked down and the nuts will be snug. I had no problem with the fronts.

I never had that problem, I got the Pacific sims?
