4WD vac system

For now I've decided to keep the vac system for my 92 Wrangler. I ordered new vac hose assembly from the dealer and new vac motor on line.
How difficult is it to change out? Particularly, how about the connections on the trans case? Are those crimped or pressed on?
What other parts might need to be changed. I want to be prepared. Its too cold right now to enjoy this type of work on the YJ.

Thanks

The hose cluster simply presses onto the vacuum switch on the tcase.
No clamps or anything.
I'd recommend you also replace the tcase vacuum switch as long as
you are replacing most everything else. The vacuum switches are fairly failure prone.
The switch simply screws into the tcase and is only about $15.

It's a fairly simple job to do. The hardest part is getting to the vacuum switch on the tcase.
Not much room to get in there with the skid plate, shift linkage and DS in the way.

yes you can!
that's how I got to mine when I had to work on my 4x4 vac system. you'll have to remove the boot, as well as the plate under it.
