Ok another silly question but I don't have an owners manual to find the answer. I have been given two answers to this question. How do you properly shift into four wheel drive. I have been told you can shift to 4-hi while moving up to 50 mph but have to be completely stopped and in neutral to shift to 4-lo. I have also been told you must be at a complete stop to shift to 4-hi or 4-lo. By the way the truck is an 88 w/318 and an auto tranny. Thanks for any help

If everything is working right, you should be able to shift on the fly from 2 high to 4 high and back again. Drivers side visor should have instructions from the factory if it is still there..
If you find that it won't shift into 4 high from 2 high on the move, then the actuator isn't doing its job. Switch on the transfer case that provides vaccuum to the actuator could be the culprit.

4 lo: Definitely stopped and in neutral

Ageed with Zeker (hey buddy!) on the shifting and the visor instructions. But, some trucks, like mine (Stupid trans -case), are worn bad enough that they won't shift on the fly from 2wd-4hi. Must be stopped to shift. Rebuild time.....
