Hey, are you guys using a marinade on those pork chops or a dry rub?
Threaded fasteners hold due to the bolt being stretched and providing a clamping effect. That can be modified by the nature of the clamped assembly, dirt, thread condition, rust, lubrication, galvanizing, etc.
Using a light coat of Never Seez or oil on the threads will reduce the amount of torque needed be about 25%. Never Seez has suspended solids in it and it effects torque differently than oil. I don't understand all the nuances but I gather that more never Seez = less torque.
If you tighten a lubricated thread to dry torque values you are at significant risk of permanently stretching the fasteners and all the safety issues that go with that. Any lube under the shoulder of the nut or bolt will further skew the torque values by further reducing the needed torque. Over torquing of the fasteners can damage any part of the clamped up assembly. In this case you can warp the hubs/drums/rotors, dish or burr the mounting holes in the rim etc.
Here's an easy to read torque chart I like.
BOLTS AND TORQUE SPECS
Although it won't help much on the roadside, I have a double shaft impact wrench specifically designed for Budd wheels. The inner shaft is fixed and the outer shaft rotates. Using a special socket, it holds the inner sud while turning the outer bolt. It would even work with the stud/bolt off the truck and just held in your hand. I was lucky enough to get mine (NOS, 1,600 pounds torque) for $125 on epay about six years ago. If you hunt, they are on there every now and then.
Lastly, if you loosen and re-torque the nuts occasionally, you'll have a lot less issues.
