I thought that nut spins with the tire.....put the socket on and then the breaker bar, set the breaker bar sitting on the ground towards the rear get any by standers either in the truck or behind a wall and drive backwards

If its not have someone in the truck press the breaks while you put a jack under the breaker bar and jack it up(slowly)

 

the jacks not a bad idea, but how do you drive backwards with three wheels?

 

I also had this idea, but since the front diff is open, I don't believe it will work. Once enough force is applied the carrier will start to spin, which would negate any force to whichever tire has the most traction (the one with the breaker bar in this instance).

Might be worth trying though, my theories have been wrong in the past.

EDIT: if you try this go FORWARD if the nut is on the passenger side, BACKWARD if on the drivers.

 

I mentioned earlier that I'm really leery about driving the truck anywhere with the noises the bearing is making. I did run down to the 4x4 shop down the road and had a chat with them. They didn't think an impact wrench would do any more than I've already done with a 6' pipe. I thought about using the truck to apply the force as you mentioned, but since my 3/4 inch breaker bar is only 17" I'd have to use the pipe and it would just bend, wouldn't it? I just found my torch, so I suppose I'll give it some heat and another try. The whole point is to change the hub, so I don't see any issue with using fire (Fire...FIRE...MWAHAHAHAH!!! Ahem...) :-)

 

heat and cool it like like you would with a bleeder on brake caliper. and if that dont help get it as hot as possable and put tention on the rachel and hit that back of it with a hammer. it will kinda jolt the bolt and should loosen up the rust

 

You put rim on with out center cap......if you dont have removable center cap you use your spare rim.

 

VICTORY!!!!!

T'was a valiant fight. My adversary fought with it's rust and momentum and miles of experience, but with my trusty torch, 2.5 ton hydraulic jack and breaker bar I persevered. After a fierce twenty minutes, flame, tension and brute force won the day. A groan and POP were the first signs of the vanquishing of my foe. As the tides of battle shifted, 4 more pops were heard, resounding evidence that the laws of physics could not be flouted. In a matter of seconds my foe gave up and spun off the axle easily. Mission Accomplished.

Of course, now it's too dark to work on it....

With the wheel on the ground, I hit the nut with my torch for probably 8 or 10 minutes. I set up my breaker bar, extension and socket so the handle was a few inches from the ground. I rolled my jack under the end of the handle, draped a heavy, wet blanket over the whole mess in case something broke loose and began to jack the bar up. I left it "up" for a few minutes to keep tension on the nut then let it down again. After a few iterations of this there was a loud POP. Four more pops and I could move the nut by hand. Thanks for the help guys. Let's hope the rest of it goes easier than this!

 

Glad you got it off finally now the easy part follows.....hopefully..lol

 

Good for you! A few years ago I had to torch mine off and replace the stub shaft.

I have to do this replacement on my truck. What is the axle nut size?
