2006 Hummer H3 Adventure Build

While waiting for parts in the mail, I figured I would change the oil, replace an axle seal, and replace diff fluids in front and rear. While doing so, I decided to triple check the fuses.
Up until today, anytime I have checked fuses, I just looked at the filament (or whatever it is called) inside the fuse. I hadn't thought to look at the blades of the fuse, however. Upon removing the BCM fuse, I noticed some suspicious scorch/arch marks on the blades... I sanded the blades clean, replaced the fuse, and guess what...? The vehicle started and ran with no warnings and everything worked as it had prior to this problem. Total cost: $0.05?
Here's what it looked like:
Corrosion on the blades led to arching and wild electrical problems!

I suppose I'll have to give in to your pressure for CRC. I haven't had problems with corrosion on electrical terminals like this in any vehicle I have owned previously (and they've all been from the rust belt except this one). Also the first vehicle I've owned with power mirrors, locks, and windows haha. I'm sure you were hoping this was all due to my questionable door-jamb job.

Impossibly Stuck Inner CV Shaft... HELP!
I started by "playing nice" trying to remove the CV axle in order to replace a moderately leaky axle seal. My initial attempts were gentle pulling with the tap of a hammer, then some gentle prying, then some increasingly aggressive slides with a slide hammer, then using a bigggg pry bar, and then separating the outer part of the axle housing to at least get it off the vehicle to take somewhere.
With it off the vehicle, I detached the inner boot and separated the axle at the spider to have a better chance of fitting it in a press. I brought it to my local machine shop to see if they could press it out. After soaking in penetrating oil for a long while, it still didn't pop free with the force of his hydraulic press.
Tomorrow morning, he's going to try boring out some material from the inner side and give the press another try afterwords to see if it's enough to release it (so I can salvage everything but the small section of axle). If it still doesn't break free, the plan is to fill the bored part with some hot magma (welds) to see if the temperature and shrinking (cooling) weld will assist in getting the splines to break loose.
If it still doesn't budge, my plan is to order a new axle housing (the small outer housing) and re-use the old axle mounting bracket.
Please, let me know if anyone has any ideas or suggestions with this. The differential fluids looks like liquid graphite, so I imagine the fluid hasn't been changed in an extremely long time (along with the CVs).

I'm glad to know yours popped out right away Thanks for you idea, and the C-clip folding is a good thought on what might be happening. I plan on stopping by the machine shop again today for an update on progress. The old diff fluid was really bad looking, so I imagine it is a contributor to the problem of either corrosion or not letting the c-clip pop out.
