yup ADD actuators are on the o/s inner wing, blue and red solenoids trace and check all the vacuum pipes to/from these and check the wiring plugs on all the electrics to the tranny case and front diff for starters

yip i know where you mean ,i can feel the vacum coming in to the solenoids,but wat do u mean by "and front diff for starters?" forgive my ignorance

sorry, just meant that the first things to check would be the vacuum pipes for leaks. And then that none of the wiring plugs in the 4wd electrics had worked loose or broken.

On the front of the front differential there is some electrical connections which you can follow back up the side of the engine, and there is a round multiplug about half way along this wire which has been found to have worked loose on a few of our trucks (well on mine anyway), and also some electrical connections on the transfer case which could cause the sort of problems you described.

These would be the simplest to check and probably the most common reasons for losing 4WD.
