neverstuck Posted February 19, 2011 Share Posted February 19, 2011 88 Jeep Comanche I'm going to be swapping out my comand trac axle(disconnect) to a Selec-trac axle In the next day or so. I have done this before on my other 88 comanche; to make the four-wheel work properly i just plugged up the vacuum lines that ran to the shift housing(well, plugged them up by the t-case) and it worked fine other than the four-wheel light on the dash was permantly on. I was wonder if you any of you guys(girls) have done this before and done something other than plug the lines. Just would like some other opinions... Thanks in Advance Link to comment Share on other sites More sharing options...
maddzz1 Posted February 19, 2011 Share Posted February 19, 2011 Command trac and selec trac have to do with the transfer case, not the axle. Command is part time 4wd and Select trac is full-time 4wd Link to comment Share on other sites More sharing options...
neverstuck Posted February 19, 2011 Author Share Posted February 19, 2011 OK, incorrect terminlogy. But do can u atleast understand what I'm talking about? I'm referring to engaging the front shaft to go into four wheel. Link to comment Share on other sites More sharing options...
Eagle Posted February 19, 2011 Share Posted February 19, 2011 Command trac and selec trac have to do with the transfer case, not the axle. Command is part time 4wd and Select trac is full-time 4wd But vehicles with SelecTrac had non-disconnect front axles. I would suggest removing the vacuum harness from the axle to the firewall but plugging/capping the lines at the firewall. I believe that's where the switch that actuates the 4WD light is located.

neverstuck Posted February 19, 2011 Author Share Posted February 19, 2011 OK; thanks Eagle man; double thanks for not just posting a post to give somebody a hard time. :) plugging the lines at the firewall is a better idea. I try it when i get to that point. Thanks man Link to comment Share on other sites More sharing options...
neverstuck Posted February 21, 2011 Author Share Posted February 21, 2011 I'm all done the swap; the old vac lines(from axle to frame) run up to three hardlines on the framerail. I was just going to cap them there. So mud n junk didnt get in. Then maybe like u were saying cap them at the firewall too so my 4wd indicator light doesnt stay on all the time. Ill have to take a look and see what goes where up at the fire wall. Link to comment Share on other sites More sharing options...
