Thank for the reply CamoRhino! I haven't had a chance to check anything out yet, but was just wondering if this was a common problem as the seals aged. I had it out at the hunting camp a couple of weeks ago and everything was okay. Did not notice any leakage on the ground or on the trailer after I got it home. Couple of days later though, and gear oil was on the garage floor and all around the rear seal. I will be sure to check the nut on the yoke collar. Thanks for the input.
