Cannot emphasize how lucky you are on this. You'd be weeping over a cracked transmission case when the axle self-destructed and whipped around at speed, worst case.
Drama aside, you cannot get away from a very careful analysis and recon. of the issue. Buying new bearings is wise I think for a 130K and up car, esp. on the drive side. But I'd check the other (left) side - did you mention mileage? - to be sure nothing is going to act up over there. You might get away with carb cleaner and Q-tips and a very good fitting allen socket for that side.
I had to helicoil one or two of the threads on the trans-side flange and plan on finding a good used one to install - I rebuilt mine with new bearings and am very happy. Do be certain to browse the links provided in this post. This is a good thing - messy but peace of mind fix for certain. Check you door stops next
