NP231 and vacuum lines

GoSlowGetStuck said:

I just want to verify - the vacuum lines going to the transfer case do *not* play a role in the transfer case doing its job, correct?

So assuming I don't care about my front axle disco or 4wd light (and I don't), could I remove the vacuum harness from the back of the TC without any problems? (I would at least cover the back of the TC to keep dirt out)

The transfer case is the transfer case, the vacuum switch will not effect its function.

That said, that vacuum switch controls vacuum to the D30 vacuum motor, so unless you have addressed the issue of the axle itself the transfer case will work but you won't have 4wd.
