Well I'm dealing with an independant carquest shop. Who frankly won't get another dime from me.
Getting the axle replaced was mostly painless. Figuring out if the store was actually going to still be open when I got there was the hard part. Once I managed to catch them open they swapped the axle out without incident.
Unfortunately its another annular joint. I checked the bolts on this one and couldn't loosen them with my L allen wrench. I suppose I'll just resign myself to inspecting them periodically.
Glad I bought those ramps...
