I just changed my rear differental fluid I took it for a spin and when I got home the differental cover wasn't leaking neither was the fill plug but it was actually the pinion seal or what looks to be. My first thought was the breather tube was clogged so I took it off and tried to put some water through it and nothing happened so I cranked up the water pressure and something shot out the end of the tube so I assumed that all of that pressure was causing it to get pushed out the seal. But I was wrong I just took it for another ride after cooling off for some time and the same thing happened it's still coming from the pinion seal and quite a lot (see photos) and only seams to happen when I stop I looked down my longish Drive was with no drops to be found. Do I have a faulty breather valve that isn't opening? Or the seal just happened to go bad? I also have a rear end whine that I've had for months when going faster that 30mph is it a bad bearing? The leaks that you are seeing are after about 3 minutes of being in park and then it stops leaking.
