Let's see-

Testing. You are looking for rotational play in a joint. I've got a large set of channel lock pliers. You could put on the emergency brake and put the car in neutral.

Then rotate the shaft between the joints for play. That should give you an idea of the outer joint. If you hold the inner joint on the diff side and get lots more play... it's the inner joint.

I would surmize that if the inner joints are available, then they should be replaceable. Probably similar to a VW or Porsche and not bad to replace.

Did you call Potomac and see if they had used axles? Is fastlane qouting you for just the axle or a kit which includes the inner flange for an extra $150 or so? If you are cash strapped, you can put the old style axle in your car....

Make sure the splines are clean of mud, ie don't strip those bolts! I use to just use a small screw driver and then tap the spline socket to make sure it is seated.
