Re: Faulty vacuum system, but engaged shift collar?
Years ago in 4 Wheeler Magazine I saw a way to actuate the vacuum motor by sucking on a piece of vacuum hose connected to the vacuum horn to either engage or disengage the collar. I don't know if this is possable because it seems like you'd get a collapsed lung from trying.
I just rebuilt the whole line system on my 87 YJ and although it now works, it was a kluge from the word go!
Since you're worried about the impending snow, if I was you I would get a piece of vacuum hose and hook it up to a vacuum source on the engine to engage the collar. Block it off with a golf tee or screw and if you need to manually switch out of 4 wheel use the engine to do it.
I was going to do exactly what you suggested, switch to cable, but I made the trip to the parts store and bought some hose and tees and fixed my ripped up vacuum system for a lot less aggravation than designing and building a cable system for a vehicle that I relied on to drive every day.
LEVE sent me a small sketch that made all the difference in the world when it came to fixing my mess. I'll do my best to attach it, (never tried it before), e-mail me if it doesn't work aand I'll sent it to you.
