Thread: Surf 4wd problem

I had an issue with my old surf a few years ago, had a vacuum actuator near the front diff shaped like a diaphram enclosed in metal . it had a hockeystick shaped vacuum line spigot sticking out of it.
I broke it off and screwed a wood screw in the hole (stuck on the beach at the time) it pushes the diaphram over and engages the front
that screw was never pulled out of there either. stayed in there for years
