A 5 or 6 Ton bottle jack. Some short pieces of 2x4 to go under the jack to get it up to frame height (NEVER jack under the axle tube). the correct socket and a breaker bar.
Set wheel chocks on the opposite side and leave it connected to the truck, if possible.
You should jack it up and remove&replace one wheel in the driveway just to be sure you know how high to lift, etc. Also, when you check the air pressure in your tires (before every trip, then at least every other day) be sure to check the spare. Nothing ruins your afternoon faster than putting the spare on and then finding it has no air.
//Advanced Theory:// You can jack under the plates where the spring pack is attached to the axle tube with "U" bolts, but if anything slips you have just bent an axle and that is an expensive fix.
The jack from the truck "might" lift it, but some truck jacks are so specialized that it is a******shoot. You can always try.
I carry a battery powered impact wrench. An expensive toy, but a leftover from a previous occupation.
