Well it stopped raining so I went to fill it up.
What mess. I had some tubing that I was going to use to fill it. Got 1 end in the diff and the other one on the bottle. Squeeze the bottle, and man I forgot how thick 75w-145 is, even though it had been sitting in the sun and was warm. I was squeezing the bottle pretty hard and pop, the tube came off the bottle and gear oil went all over my tire and rim (and me!). Crap. What a mess.
I ended up just crawling under and putting it directly in the diff. A little more of a pain, but easier to squeeze the bottle.
And another thing, the Motorcraft Friction Modifier stinks something horrible. I mean gear oil stinks, but this stuff is just horrible. I mean gross. I deal with all kinds of body smells all day at work and this is worse than any of them. And it won't wash off. I think I am going to have to throw away my shirt and rag that got some on it. I showered and soaped up 3 times and I still smell of it.
And an ironic thing, I went for a test drive, turned around in intersections a few times and such. Well, road was still wet so I figured I would do a quick tire spin to see how it did (have not done one in years). So I get on a road with no houses and do a burn out, and as I get to the intersection, constable is pulling up to the corner. He follows me to my house and asks me how its going. I explain what I was doing and he laughs and tells me have a nice day.
I also noticed that the pinion is leaking some, so I need to look into that. How hard is that to replace?
Edit: a quick pic, my Limited slip is working.
