Borrowed these pics from lovingtheride, hope he don't mind.
Does anyone now what that seal is on the inside of the axle tube is? I keep getting an oil leak ever since I changed my axles and I damaged one of these getting the old one's out and I can't find these anywhere. Do they actually seal anything or are the just in there to keep both axles sealed from each other. I've done replaced both outer seals thinking it was them, but am still getting a slight oil leak.
