Jake720 Posted December 24, 2019 Report Share Posted December 24, 2019 I have done a vacuum delete of my egr. Just wa Ted to see if anyone has an idea on what vacuum lines control the 4x4 automatic hubs? I have no idea if they have been disconnected before I took out the egr lines since there were already lines capped off. Quote Link to comment
datzenmike Posted December 24, 2019 Report Share Posted December 24, 2019 EGR is a ported vacuum source from the carburetor. There is no vacuum signal at idle and this would be no good for the hubs, so instead, intake vacuum would be used. Try to engage the hubs. If they work, then they are connected. Quote Link to comment
