No... you posted as "Jeepster" and the other guy is "Jeepers".  As far as
your YJ... it is vacuum activated, and prone to problems.  There is a
modification that eliminates the vacuum actuator.  I'm sure someone will
chime in with the link (Bill).

I was posting as Jeepers and just realized that someone else posts
here using the same name ( or someone else use to use that name) so
you will notice I changed my nick a bit.

Anyways 2 days ago I had my vehicle in 4WD and today I went to work
and noticed that the front axles are locked in 4wd. The indicator
light does not indicate that I'm in 4WD and responds to me shifting in
and out of 4WD. From what I have read when I shift to 4WD the transfer
case of course shifts the gears and via vacuum it trips a pressure
switch to energize the indicator light.....this all seems to be in
order. Also I understand it also applys or removes vacuum on the axle
shift motor and engages / disengages the front axles.

So from this I guess I can assume one of the following:

1:) I have a bad vacuum line
2:) The shift motor diaphram is damaged
3:) The shift linkage from the shift motor is damaged / jammed

Is there an easy way to manually disengage this until I get time after
NewYears to really look at the problem.

Also does it apply vacuum to engage the front axles or remove vacuum?
