thanks for the info! I guess my next question is:
What is the advantage of taking the time to switch my transfer case from a vacuum to mechanical system? If I don't switch to mechanical will I lose the ability to engage 4wd?
I have an Fj62 I'm looking at putting a new H55 in. I only have one question: will I need a new transfer case for the H55 or will the existing one I have on my FJ62 work?
