Have you taken the wheel off and looked at the axle yet?The area I'm thinking about on the rear wheel has some grease but the oil is in the transmission and the shaft from the rear wheel goes in it but there is ujoints in between so ...I would check the transmission oil level and make sure it's not being slung on it from the transmission. The seal is pretty easy to replace with basic tools. Jack up the rear and check the bearing too by trying to wiggle the tire before you take it off. Let us know what you find. Bordercollie
well i pulled the wheel and theres no oil coming from the trans. The backside of the rim is also dry. The inside of the hub cover is dry with no indication of seepage around the bearing seal. The assembled Wheel has no play or loosness and all looks like new. theres 330 hours on it. Only could think oil was either sprayed on the rim or theres oil in side the tire leaking out which is hard to believe. Wiped it all down and will be watching it closely. Maybe we have a talented animal that pees oil
