Im not so sure that they suddenly stopped working, I bought this jeep this past March and have been fixing stuff ever since. It had been sitting for about 5 yrs and some guy got it running and sold it to me. As far as the hub I rebuilt, there was no gasket on it and the bolts were not tight and did not have lock washers on them when I took it off, so thats how they got dirty. Ive got a manual that shows all the parts, and I assembled them accordingly (twice) and everything seems to make sense mechanically. I just dont know, there has got to be something Im missing or dont know. I think I will pull the other hub off and make a quick inspection asap.
