lean it up with a lot of degreaser first and then pay attention to it. could be your fill plug as well as your pinion seal for what I could tell from the pics. Not really sure how it could get to your e-brake from there though. Guess it could be throwing it up from the DSn, but I would think it would be farther back.

Not too hard at all. Can be done in the driveway, no problem. If you aren't familiar with it, youtube can be a great help, as well as a factory service manual. As for the other two, new RTV for the cover and teflon tape for the fill plug.

Just replaced mine and the fill plug about a month ago. Mine looked identical. The hardest part of replacing the pinion seal is breaking the pinion nut loose. I started off with just 1/2" drive and wouldn't budge. If you can get to one I had to use a 3/4" drive and the push of one of my buddies...of course if you have a impact then you have no problems lol but you will need a 1 1/8 socket for the nut. Theres my pinion seal story lol but like he said ^ easy drive way fix.

So I started it. I got to the Piñon nut and I have an impact wrench however my air compressor is too small. I could not break the nut loose. Luckily my neighbor is a diesel mechanic and I'm waiting for him to get home. I'm thinking I've got this in the bag however I'm a little nervous doing it. I'm a pretty good handyman/mechanic but I've never done this before.

yes whoever or whatever installed the nut from factory put the wrath of god on it because it is very tight. thats what i am is a diesel mechanic so that helped me out alot with already having the tools i just dont have a comressor at home for my impact. but once you get it off and pull the pinion out the seal looks like a mini wheel seal. a pair of channel locks or a heel bar works perfect to remove it. when you put the new one in be gentle with it because i have seen them broke from banging to hard on it and make sure it seals good. and goodluck getting the nut back that tight without a tourque wrench.
