I have a 1-1/2 inch 3/4-drive socket I bought years ago when I last owned a big truck. I don't recall how I determined the correct size, and though it was a GMC the running gear was all military Dodge, so I doubt it will fit my big Chevy trucks.
You guys with big trucks, how do you get the wheels off? Do you generally take the truck somewhere, or just use a big breaker bar? I doubt my little compressor and air tools are going to deal with 250 ft-pounds of torque...
