One of the tubes to activate the four-wheel-drive broke a number of years ago and four-wheel-drive stopped working. The tube was patched and repaired, and it worked fine for a while. Now it has stopped working again and I am assuming the tube has broken again but I can’t seem to find it, any pointers on where it is? I thought it was on the passenger side near the battery, but I can’t seem to locate it. Your help would be much appreciated!

Hi,

The vacuum actuator is located on the passenger side of the front differential. From there, they run to the vacuum solenoid on the inner fender.

I attached a pic below. Let me know if this helps.

Take care,

Joe
