[QUOTE="Dane, post: 1267062, member: 2494"] I don't think it's your vacuum lines. Those only control the front hubs and there are no sensor type things to cause those to complain if they do have problems. It sounds like your tranny isn't even trying to shift which leads me to think it's whatever solenoid type thing physically shifts the tranny into 4. HOWEVER, if you want to mess with the vacuum lines, crawl under by the wheel and you'll find this dual rubber line on the top of the IWE. It pulls right off and by doing so you are engaging that hub to the axle. Repeat on the other side. Now your front axles are in four wheel drive, but I don't think it will matter because I don't think your transfer case is shifting. Technically you should plug those lines if you want to try driving around, but if you're just testing it in your garage or something I wouldn't worry too much. Don't forget to hook the lines back up. In short, I suspect an issue in your transfer case. [/QUOTE]
