axle shaft nut removal help

So decided to change the hub bearings on the ZJ. Ive tried everything to get axle shaft nuts off. PB blaster, propane torch, impact gun, put the wheel on and put on the ground and my 190lbs bouncing on the breaker bar and these nuts wont budge. thinking it might be easier to just get the bearing and axle off together. and replace everything but the new shafts don't come with nuts. Any other ideas to get the damn things off, Oh and as far as i can tell they are original from 1998.


Thanks

i've never had one not come off with an impact gun. and i've done them in 3 vehicles. you might have to scrap these and get new shafts with nuts.

I have a 3' length of conduit that I use for a cheater bar that's never failed me. "Give me a lever long enough..."

I put it in my "special equipment" arsenal years ago when I had an MG with knock off wire wheels. I spun a wheel on the splined hub. They are designed so if that happens the knock off nut tightens instead of coming off. It's a great idea for safety, but you end up with the knock off getting torqued as tight as the momentum of the entire car can get it - which is pretty **** tight.

Living in southern CA, I've never really had to deal with road salt type rust though.

Tried a cheater bar? They're torqued to 175 ft lbs (from the factory). When I took mine off the other day, I had to use a little man-manuevering with a 3' cheater bar to get them to break loose. 1/2" (or bigger) drive breaker bar, cheater wrench, heat then penetrating oil and they'll come off.

Otherwise you can just remove the axle shaft with it. Three (13mm?) bolts hold them onto the knuckles.

Those nuts can be a pain if one lives in the salt belt and hubs have never been replaced/ not replaced in a long time. But, 1" drive 36mm socket, 1" T- bar with 5 feet of strong tube as extension will do it.

I use 4' of fence post! Torch will help some too, try not to over heat the axle itself though.

I had to pay my mechanic to do mine. I literally was standing on my breaker bar jumping up and down on it. I think he ended up using a breaker bar with a pipe extension over six feet long.

Like I wrote above, use a sturdy breaker bar/ T-bar for 1" sockets, and a long enough extension. No bolt or nut exists that does not crack loose with enough leverage - unless it snaps/ cracks.
