Like I posted in the other forum...the MB 72s are the same way. The lug nut kit DTD shipped me had a special socket to use with the lugs. If you didn't get one, let them know.
Also remember that impact guns should never be used to install lug nuts. They need to be hand torqued to the proper spec.

My favorite quote from the press release.. sad but true: "Chrysler claims its products, especially the Jeeps, can handle all sorts of terrible conditions, churning through muddy swamps, climbing mountains, and crossing rivers. Turns out they cannot even handle a car wash."
