I was trying to change my Rotors on my 81 Chevy Blazer with manual locking Hubs, I got as far as removing the Locking & Unlocking mechanism then after that I didn't know what to do. I am used to working on my 2wd so this looked alot different. So my question is what do i need to do to get the Hub off, After I removed it all I could see was a Gear and nothing else. Any help would be Greatly Appreciated!!! 2-wheel'n all the way!!!
