Question Thought it was a rear shock leak, but now I'm not so sure

Noticed an oily leak when I was changing my wheels. Right rear shock looks completely covered in oil so I was prepared to order a new set but then noticed the oil staining all over. Now I'm wondering if it's even oil from the shock. What else could be leaking onto the lower arm? Oil didn't have a smell.

It's on a 2010 Mazda 3 2.5L hatchback.

Interesting.. looks like it's been leaking for a while :P

I'd guess it's just the shock. IF the hub was greasy like that and the shock was dry, that would point the the rear wheel bearing but since the top of the shock is wet, I'd say it leaked so much it started to creep up the trailing arm.

I took the wheel off again to take another look. The brake line and bleeder valve look completely dry. The other line is the parking brake I think so that can't leak. I can't think of anything else that would leak in that area. I'm ordering a set of rear shocks to replace just in case, it's probably time to replace anyway.
