Clean both splined faces thoroughly, smear on a good epoxy, or even better - a loctite product for fixing bushings in place. Press nub into hub, allow to cure. Reassemble body. Ride on.
The threads inside the hub body are stripped except for 2 at the end. Once the freehub body is back on the threads are too far away for the bolt to catch... I am just gonna order a new one. Gah this has been the biggest pain in the ass! I should have taken a better look at it when it first blew up. Either the weight on it just caused the bolt to come out or whoever I bought it from serviced it and never screwed it back together properly. The way it is stripped though seems like it just worked itself out. I assume the grease squeezed through the cracks since the freehub body wasn't connected to the hub.
Thanks for the help!
