I have WARN hubs also. Best thing I ever did. I have a 98 Sportge as well. I tried replacing the hoses at first, but continued to have problems. I would be in the middle of a snow storm and the original hubs would kick in and out. Horrible design, that is why they changed it. Unfortunate for some of us, we got stuck with it. It was very easy, took les than an hour to change both sides myself with basic tools. So easy my wife could have done it.
