I don't like to ask questions until I search and try to find answers, so after an hour of searching I have to ask. I have a 1990 suburban 2500 350 4 speed 208 case. So my issue is I have to power to the front tires, the auto hubs have been replaced at some point with manuals. The T case engages and goes into low but no 4wd Ive read something about and actuator or maybe a fuse? I almost bought a pair of new Warn hubs, but if its electrical I'll still be without 4x4...........thanks in advance guys.
