Looks like tons of fun.

I've popped on out before on accident when doing ball joints and tie rod ends on my old Z34. If the suspension set-up is remotely close, then it shouldn't be too much of a problem to get it out and get the new one in.

Are we sure which this is yet?

Constant drone sound would typically be wheel bearing
Clicking would be axle.

Have you inspected the CV boots for tears?

Not a constant drone, only vibration while turning.

I'm gonna inspect today while I have some free time between class and work.

No tears in the CV Joint boot. While the front wheel was off the ground, I checked the ball joints and tie rods, look good, and there was no left-right or top-bottom play in the wheel, so I know they are good.

So either wheel bearing or CV Joint/ half shaft.

How can I test for bad wheel bearing?

nearly all wheel hub failures will present themselves with either a humming noise, or with some movement in the wheel itself, which you have confirmed that you do not have either. So i would go ahead and rule out the hub as a possibility, im putting my money on it being an axle

And typically an axle would be a clicking sound when performing a fully locked turn.

You could do what Mechanic Dan says to me. "I realize you are in tune with your car and can hear every noise. I can't hear it yet. When I'll be able to hear it..then ask me...meanwhile..turn the radio up"

Meaning.. the issue may not yet be bad enough to make a good determination. Sometimes the best course of action is holding off until you can tell which part needs to be replaced. Otherwise..you'll be shotgunning a ~$100 bearing or ~$80 axle on the car and possibly choosing the wrong part.

not necessarily... GM axles hold up VERY well, an dit takes a long time for them to start clicking.. I ran one of my axles for about a year without any grease in it before it finally started to make enough noise for me to bother replacing it. but it did make the car vibrate alot more, especially when turning

That'* why I said "typically".

And then warned about the possibility of putting on the wrong part. It is possible that all who have posted so far are incorrect and the issue is the tire rubbing on the fenderwell. We didn't suggest checking something so simple.

I've already checked the tire well, no damage. With the axle shaft only being about $100, I may just go ahead and order it and just do it. Looks like a 2-3 hour job, if that.
