I was surprised as well when I heard it and I did some digging. I found plenty of threads discussing it, so apparently it's fairly common for the MSM's pilot bearing to fail in 45-50k? All recommendations are to not replace it with the OEM one, though I didn't find any reference of if other brand bearings actually last longer. Plenty of NB Miata references regarding it as well, so possibly not just MSM.
Yes, we have tickets and hotel paid for already. Presumably I am picking it up today, though if not we will be staying the night down at my wife's sister's house tonight and picking up tomorrow would helpfully be the fallback. Otherwise, I won't be able to bring it, and we will just have the 2. No reason left for delays though.
