Looks possibly like there is a little seepage going on. @NCFJ and @lt1fire had mentioned in an earlier post about leaving the inner oil seal out just a bit so it rides on the axle shaft in a different spot and I think as our vehicles age that needs to happen more often than not. @jfz80 was the first to tell me about doing that this past week and that's what he did on his front end rebuild.
