Ok so the seal I was assuming was inner is actually attached to inner bearing correct? And if that is the one is it pressed on or how does it come off and I measured it and its smaller then 5.5in it's more like 5 19/64 but could someone have got wrong part and jus put on and that's why grease and gear oil covered inside of drum/brake mechanics cuz it was a mess and im not even sure it is a wheel cylinder that's leaking think it's just the axle seal, but probably gonna check cylinders while I'm in here like this and btw how can I test leaking wheel cylinders with drum off or is that even possible cuz I don't wanna put back together after I fix axle leak and find out cylinders are leaking and have to take all back apart??? Or if I'm doomed to that someone jus rub the salt in for me haha so I know what needs to happen cuz I don't like guessing/learning from mistakes would rather learn from other ppls mistakes/experiences...that have succeeded of coarse lol
