Dave, here's the whole nasty story... LOL
Here's the kit from NAPA, (company by the name of 'Warn'- same as Amazon), with instructions with great pictures.
Pop off the cap, here's what you see...
6 bolts, wiggle it off...
Set the new hub to "free", so you can line up the bolt holes, pop it on, run in the bolts to 25 ft-lbs...
And you're done!
Took me 5 minutes per side, it is absolutely that easy, with the vacuum-type hubs.
Pre-vacuum-style, Kia used a "cam"-hub, and THAT style requires some 9 steps for the swap, (requiring a snap-ring pliers) because there's other things to remove and replace under the hub, (the extra pieces in the kit).
Couple of other things to consider.
1) The cap doesn't fit over the new hub, if cosmetics are a concern. A hole could be cut in the cap, but then you'd run the risk of having water/crud collect in the cap.
2) For added water-protection, I think I might pull them back off and put a thin layer of silicone at the hub edge and maybe under the bolt heads.
3) It says 21-25 ft-lbs of torque on the bolts, which doesn't seem sufficient to me, as those bolts are what conducts the movement from the axle to the wheel, (via the hub). I'll be curious what you think if you do it.
4) A review on Amazon said that the advertised-hubs were chromed, but the ones that arrived were black like mine.
Lastly...
Last thing you have to do is take care of the vacuum system.
There is a hose from the manifold (#1) that goes to a small tank, and from there to a solenoid (#2) which opens the vacuum to the wheels via a hose (#3) and the arrow shows the T-connection which splits the vacuum into two directions, and where the wire comes to the solenoid (#4). The wire pushes off the the bottom with a screwdriver, and I covered it with electrical tape and taped it to the manifold hose, so it wouldn't short out on anything. I assume the activating-switch is thrown when shifting the transfer case.
I may track the hose backward to the manifold and cap it there, so that there won't be even the smallest drain of vacuum off the engine to the tank that would have still been connected.
With that last step, I figure I'll gain maybe another 20-22 horsepower. LOL
Idrove it to a hill on my property, gassed it in 2WD, and spun the rear tires, then put it in 4wd, hit the gas, and away I went!! Too cool!!

Today's Featured Article - History of the Nuffield Tractor - by Anthony West. The Nuffield tractor story started in early 1945.
