I have noticed since day one of ownership a rattle near the right rear dual. If I hit a bump just right it rattles pretty good. My wife noticed it if that tells you anything

. I was using the power washer the other day and noticed oil al over the shock at the right rear dual. I was sanding the white top off of my bus and replacing the elastemer so I could not slow down for a rain cloud was threatening me. It got dark and that is the last bit of time I had beofre the work week started.
Would htis more than likely be a seal in the wheel hub or do the shocks leak oik when they go bad? I am in the line of thinking the shock is bad and thus the annoying rattle.
