Can anyone tell me how hard the warn #61918 automechanical hubs are to install on a 2001 sportage? Any special tools needed?
Thanks.

Remember you need a complete kit: hubs, cams, spindle nut and lock pin.

I have these hubs and they work very well. SOme precaution though: contrary to the vacuum type they MUST NOT be engaged on the run. SOme will insist they do..yes they will engage a few times but with a terrible bang.
ALso you can switch from 4 to 2WD at any speed and then the T-case is off, but the hubs are still ON and all shafts are turning....so in THIS condition you CAN return to 4WD on the fly because all shafts ALREADY rotate. BUt NEVER if they were OFF from the start.
TO disengage the hubs you must stop and back off a few feet. You then CLEARLY hear them Click-Click off...just as you hear them click-click ON when you start on 4WD.

Thanks LMP. Would you happen to know where I can get a spindle nut socket? 2001 sportage

Well ..no.
It is not very tight and will most probably rotate easily using light hammer side blows with a heavy screwdriver or the like in one of the slots ..not the most elegant way of course ..but it works...and the one you remove will not be reused anyway so it puts you on the learning curve at no cost...
otherwise in other occasions I had built a "socket" using a piece of 2" pipe and a file to built the teeth..or ..for a lesser pain, soldering a pair of protruding bolts or 4 in. nails to a piece of pipe......then using a pipe wrench to torque it out..or in, or drilling a hole through the pipe and torquing with a long and heavy screwdriver.
