99 SPD 4x4 hub conversion

I,ve recently converted from the oem auto-lockers (electronic shift) to Warn premium manual hubs. Nothing in the Warn install manual mentions what to do with the vacuum control of the oem autos. I'm not sure what to do at this point. Have used the 4wd without noticing any problems or noises. Any advice out there!!!

You have to block off the vacuum lines.. Up under the hood or down at the wheel.
Merry Christmas and welcome to the site.

Appreciate the info Dick, kinda figured this to be the way. This is a 7.3 PSD, noise and pump vacuum probably masks any changes in vacuum when 4wd engaged. Will cut and inline plug the lines as to not contaminate either side of the line. As a side post, anybody heard of a rebuild kit for the oem auto hubs.

No re-build kit, that would be counter-productive in stiffing you for $300 each for a new auto hub. The stock auto hub is a pretty light weight unit when compared to the Milemarker Supreme manual hubs, so I don't know if the cost of re-build parts (if you could get them) would be cost effective. I have a pair of auto hubs sitting in the basement that I may mess with if find the time just to answer a few of my own questions. At this point I'll never take the Milemarkers off, they're too sweet
