I am having trouble modifying the switch to 4WD. I took the vacuum out because it was pretty much gone and ran a cable to it to change it. Now I am having problems with the transfer case not working properly. I also took out the differentia due to leaking badly. I had 2 old axles that I took apart to put the ends back in the hub to keep driving it. I could use some advice to finish my project because the vacuum is not safe when you are out there.

Thanks Paul
