Decisions decisions...

Need some insight guys. I had barely freshened up the rear end, its a strange narrowed 9" with strange third member and 35 spline spool with dutchman axles. After a turn and some speed I heard a snapsnap, then the car shook a bit and sent me into a spin.
I was able to keep the car out of a wall and limp it home. The splines on the spool got completely sheared off on the passenger side. Axle is fine, nothing at all just the spool's splines were messed up. Now my question is. I know I'm probably thinking of what it should be. But how dumb would it be if I reused the bearings being that they're fresh? Just take it apart and drop another spool in it. Stupid or just spend the money and do em over? I didn't look at the spool before and pretty sure it was starting to mess up before. I mean the bearings where the spool is at. Others I have new, but these I do not.

Change em out?? Just kick myself for having to do this again. Also how often does someone break a spool or an axle with a spool on the street? My tires are 20" wide as well. Could it just be bad roads and I wasn't making my turns wide enough?
