Greetings, I have a '71 Fj40 with stock drivetrain. I've been noticing a larger and larger oil leak from under my transfer case. I found the leak coming from the joint where the vacuum actuator bolts to the transfer case and also leaking from a missing bolt hole (see pic below). There are 4 bolts holding the actuator to the transfer case and one of them is missing(see attached pic). I thought 'no problem' and tried installing a new bolt. But it looks like the bolt broke off flush at the transfer case! So now I have to remove the actuator, drill out the bolt, rethread and reinstall. My question is....Is this as simple as removing the remaining three bolts and sliding the vacuum assembly out? Or is there more disassembly that needs to be done? Thanks for any assistance.
