Time to pull the Warn hub. It is necessary to disassemble the hub since the wheel studs must be pressed out in order to remove the old rotor and then pressed back in with the new rotor attached.
With the caliper out of the way, it is time to get the hub off of the spindle. I labeled the above photo with the names Warn uses in their hub conversion installation docs to make it a little easier.
Remove the axle retainer. I use a needle nose pliers to push the open ends of this springy clip of the groove that is machined into the axle stub shaft. Be careful you don't "pop" it across the driveway or garage floor into some unknown place. If you do, your spouse will have to come out to the garage to find it for you. (don't ask me how I know)
Slide the spindle washer over the splines of the axle stub
shaft. You will need to line up the splines of the washer to those on the stub
shaft so you can slide it off the shaft.
Using a Dana 44 spindle nut socket, remove the outer spindle nut. This is normally torqued to 150 foot pounds so you may want to use a 18"~24" break bar to break it loose. What....you don't have a spindle nut socket? They can usually be had at an auto parts store for about $12~$15. I got mine from the local Pep Boys a number of years ago. Unscrew the outer spindle nut (once you break it loose) and set it aside.
With the outer spindle nut out of the way, the lock washer can be slipped off of the spindle. Set it aside too.
Now remove the inner spindle nut. You may or may not need to coax it loose with the spindle nut socket. It is not torqued very tight so is should be very easy to unscrew.
