Really Nasty Rear End Fluid - The 1947 - Present Chevrolet & GMC Truck Message Board Network

So I got ambitious today and when I checked my rear end fluid level I noticed it was a nasty sh!t green color and smelt like it too. So I pulled the cover it looked like green pudding flowing out. What the heck made it so nasty?

never changing it, nows a good time. mud is usually brown, so im guessing nasty pond water. growing some algae up in there.

might not be a bad idea to either flush it or change the oil again after a 100 miles or so.

Some people never change it and it has a mileage life.Yeah old gear oil does have a special funk to it.

Yeah dude. Gear oil gets pretty stinky. Nothin to be too concerned about. Just change it and make sure your breather isn't clogged. The gear oil we use here at work is actually green right from the drum. The only thing you really need to worry about it is BIG chunks of metal in there.
