I changed the seal on the outside of the 4wd vacuum disconnect and its still leaking at the knuckle. I am at odds of what to do. The only thing I can think of at this point is that the outer portion of the shaft has a small amount of play in it, and perhaps changing that little bearing on the inside of the female recession at the end of the inner portion of the axel may tighten things up. Or buying new shafts but I really dont want to put money into this crappy axle.
