If the codes are not list you can check it yourself by jacking up the back of the truck, chock the front wheels first. Then put it in neutral and mark the driveshaft and the tire. Have someone turn the tire one complete revolution while your counting how many revolutions the driveshaft makes.
If the driveshaft turned just over 4 complete turns it's a 4.10 if it turned
3 and 3/4 turns it's a 3.73 and so on.
