I ordered 4 stainless posi-lube dust caps online.  I will regrease and install the caps now then take all 4 apart, replace rear hub seals, repack bearing and re-install this winter.   I apreciate the help and tend to agree the hubs, bearings, races are probably all in good shape but will inspect and repack after fishing season.   I feel dumb b/c didn't know what the posi-lube system was until recently!
