rear end leak

no I'm not talking about eating taco bell, I'm talking about my 14 bolt ff.

see the oil around the bolt below the uv joint? what seal causes that and how hard is it to replace?

what you are guna need to do is drain the pumpkin, unbolt the pinion with those 6 bolts, slide it out, clean the area up, and put a good healthy amount of RTV to give it a good seal and bolter back up

EDIT, after taking another look at it, it could be the pinion seal, wich is right behind that yoke.
You are guna have to take the nut off of the yoke if that is the case, slide the yoke off, pop out the old seal, and put in a new one. put the yoke, washer and nut back on(dont forget locktite!) and tighten her back down. Im not 100% sure what torque rating to give it tho but im sure someone on here will help
