Hatterasguy,

I figured I would replace them both as long as I had the box out. From what I can figure out, the top seal is pretty easy. I'm hoping the bottom one is the same. I think it is. My Pitman arm appears to be snug, but not tight enough to require a hydraulic press to remove or replace it like some have mentioned, so that should make things a bit simpler. What's required to get at the bottom seal?

Do you know if there's any kind of pressure relief valve inside that can get plugged up causing it to blow out either of the seals, because it was a pretty catastrophic failure. That's why I'm hoping to find someone with experience in rebuilding one of these things so I don't miss anything. If it's nothing more than a seal, I can't see spending $400 dollars to replace the entire gearbox.
