As the title says, I am trying to remove the front axle steering knuckle. The inner seal is leaking and I need to remove the entire knuckle to get to the seal. I have removed the planetary assembly, I have removed the 3 cap screws that hold on the king pins for the axle. I can not get the king pin cap to budge. I have tried prying and tapping with a hammer but I still cant get it to move. Does it require a special puller? Any help or advice is appreciated. Thanks.
