No hidden fasteners. Sounds like the axle is rusted onto the bearing splines; if you're going to pull the knuckle, you're going to take the CV (axle) out with it, and the other end of the axle snaps into the transmission. You're making a big job out of a 45 minute job.
I've done these GM wheel bearings several times, all you really need to do is loosen the axle nut to being flush with the end of the axle, spray the splines with some Kroil or other good penetrating oil, and use a 4 lb. hammer to break it loose.
DON'T screw up the threads on the axle, you'll make it worse. You can buy a new axle nut, if you buy a Mevotech bearing on Rock Auto, it even comes with new mounting bolts and a replacement hub nut:

The new 34mm nut torques to 118 ft. lbs. Feel free to PM me if you have ???
Yeah, well aware, and of course I tried all of that.
Axle splines are rusted to the bearing splines.
My opinion sir, (which you may consider worth what you're paying for it) is all you
NEED is a bigger hammer and the anger management/C-C-C-Courage/determination to
NOT let a little rust get the better of you. I've used a 12 pounder to do this when necessary. How do you think a shop (on flat rate) would handle this? Cinch that puller down and
THEN rap it...I wish you well. Please keep us posted. I like learning new tricks...
I will find a larger sledge hammer, and try that before pulling the whole assembly.
