How to remove vacuum transfer switch?

I have read all the posts on about 4wd problems and vacuum issues.
Mine keep going into 4wd on its own. Sometimes it is fine then it drops back in.

I checked the vacuum lines and they seem fine.
I tried to remove the vacuum transfer switch and found it difficult to get too.
It is on top of the transfer case and is blocked by the linkage.

Is there an easy way to get to it?

Any help would be appeciated.
I am not a mechanic but dont have a problem doing easy things.
I have a YJ 95

I used a 1/2 drive socket (13/16 ?, but don't remember for sure) and ratchet. The handle was pointing to the rear of the Jeep and I got a click of a turn at a time.

i have a 2005 jeep TJ and was wondering if the switch from the yj is the same for my TJ. my dash light will not aluminate and i here that it could be the switch, but note that my 4wd works just fine just the bulb doesnt and does it matter where the lines go??

Mine was very difficult. Although i did it when I was unprepared and in the middle of the snow covered alley with no jack, but I managed to squeeze under. A deep well socket is def. the way to go, but I didn't have that so I had to use a strap wrench. Space didn't allow for much room, but I eventually got it. The most difficult part for me was the the new switch didn't seem to have the same thread pattern, so when it was tightened, it didn't line up with the vacuum harness the same. The rubber hardness and four vacuum lines where VERY difficult for me to twist almost 180 degress to get it to match up. Maybe it was because it was cold. Don't know. All in all, my 4wd has been working great since.

Good luck to you.

I pulled the shift boot off and got to it from the top. From underneath I put a deep set socket with an extension and universal joint on the vacuum switch and got the extension to poke through the hole for the shifter linkage. Think I had to put the socket on the switch, then angle the extension through the hole before connecting them. It shouldn't be on there too tight.

The TJ doesn't have the axle vacuum disconnect system that the YJ does. I think the TJ axles are always engaged.

Did you verify the light bulb was functional and the socket it is in works properly? I always try to go for the simple things first since 90% of my fails are simple and I dig too deep to fast.

No, they're talking about the vacuum switch that those lines are connected to on the transfer case.
