We'd need to know if you were referring to the outer or inner nut (or both), and also if your truck has the proprietary Mack axles or if it has the Dana Spicer axles. For the Dana Spicer axles, I can tell you you set the inner initially to 300 - 350 ft/lbs to seat the spindle, then you back it off, tighten it to 50 ft/lbs (then tighten it as needed to get the perforated ring aligned properly with the inner spindle nut), and the outer to 250 ft/lbs. Not sure about the Mack axles.
At a Mack Trucks dealership.
Mack doesn't make a pickup '1/2 ton' style truck.
Either a Mack or a Cummins engine.
Either a proprietary Mack 18 speed or an Eaton-Fuller 18 speed. Various models of the Eaton-Fuller were available, from 1600 torque to 2100 torque.

Many cities have an authorized Mack Truck Dealership. They offer new and used Mack trucks for sale or can help you locate the model you want. If your city or surrounding area does not have a Mack Truck Dealer, you can also look in your local newspaper classified ads under "Used Heavy Equipment" for Mack Trucks.
because Mack and Worldwide had contract, which were signed my Moore, that protected them
Anywhere from 13,000 to over 20,000 lbs., depending on specifics. Mack tended to be more focused on vocational vehicles, so the specs on their tractors can vary greatly. The wheelbase of the truck, the axle weight ratings, whether it has a single or double frame, any additional equipment (such as PTO systems), etc. will affect the tare weight of the vehicle.
