Front Hub nut tool

Is there a special a special tool to torque the front hub nut correctly or do I have to make one? I have a 97 Rodeo 3.2L 4WD that I'm currently putting back together (finally) and the manual (Haynes) says to tighten the hub nut to the specified torque but this isn't a Hex hub nut, it's a threaded metal ring with holes in the front. Looks like I'll have to make one so that I can use my torque wrench. Also, the Haynes says that I should preload the front bearings for the older type hubs but does not say that for the newer type. Does that mean I just torque the hub nut and that's it?
Thanks.

I sort of made one out of another tool. I bought a hub nut tool from the local parts store for a 1/2 ton ford. It has 4 prongs sticking out of it. Just cut off 2 opposing prongs so you have 2 opposing prongs left. Then file down the remaing ones a little until it fits properly. I got the idea from a write up on one of the isuzu forums for repacking bearings. A dremil tool comes in handy for this but wouldnt take very long to do with hacksaw and a file.

The torque values listed arent very much. I ended up using adapters and my little 1/4" drive torque wrench to make sure I didnt over torque it. I recommend torquing it quite a bit while turning the hub (even higher then the 22 ft lbs haynes says) to start with then back off to torque to the proper value. Just to make sure everything is properly seated. Dont know how high I torqued mine at first, I just do it by feel.

I use a hammer and a screw driver. I've done enough wheels bearings to know when they are too tight or too loose.
