Cant shift to 4x4 drive
I have a 92 jeep wrangler and am not able to shift it into four wheel drive.
The linkage is all good and it shifts good. Also the 4x4 light is always on
even when not in four. So i looked at the senor and took off the cover where
the fork and the bearing cupler is (THe spot where u can see 4 wheel drive
locking in) I can move the couple over by hand and 4 wheel drive will work
then but so i was thinking that the fork wont move it over by its selve. I
looked at all the vacuum hoses and I bought a new Vacuum diaphram thinking it
was just low vacuum but that didnt help either.

Re: Cant shift to 4x4 drive
You describe a common problem on YJ's. Did you also check the vacuum line
going to the transfer case?

Re: Cant shift to 4x4 drive
I had a trail buddy with a CJ7 that used to think it was funny to pull off
the vacume line that attached to the diaphram on the front axle of my YJ
when I wasn't looking. It never failed, he always waited until right before
we hit a steep incline.

Re: Cant shift to 4x4 drive
I am thinking you are talking about the front axle disconnect?
That would mean you need to open it back up and apply vacuum direct to
the shift motor to see if the fork moves. It is possible the diaphragm
is torn inside the unit.

Re: Cant shift to 4x4 drive
I am thinking you are talking about the front axle disconnect?
That would mean you need to open it back up and apply vacuum direct to
the shift motor to see if the fork moves. It is possible the diaphragm
is torn inside the unit.
