Well today I was out admiring my beautiful rig, when I noticed that I have a decent lil puddle of gear oil sitting under my hub on the rim.....where do i start? Lol

 

A little more info might help. Model and year.

Oil seal on the end of your axle. Should be a cap you can pop off to gain access to the outer axle bearing. Those seals go bad and leak onto your wheel but also your brakes. I am assuming this is on a rim bolted to a solid axle.

 

Front side of rim, or back side? If on the front side I would agree with ^, if on the back side, its ur inner axle seal.
