Awhile back one of my hubs went bad.....yadayadayada I coverd that in another thread. I replaced them with selectros, which Mace said are far inferior to OEM. What I did not mention was that soon after a little grease was leaking out of the outermost seal. I had it to my mechanic for something else but he took a look at what the problem might be. He just said that the grease that was in the birf's was too light, had turned to soup, and had to come out somewhere. I never did quite buy that, and after searching around Mud, leaking anywhere does not sound good. They no longer leak, don't make any noise or feel like something is wrong. Am I due for a rebuild (260,000 miles, but if it ain't broke don't fix it) or can a leak like that actually happen? I did't have a torque wrench when I did the job, but I got the bolts good and tight.
