    We buy actuator for all our Chevys. They are just like little plugs and nine of our 4wd have gone out since. They're a great buy and only go for like a hundred dollars. If your 4wd keeps going out then just get one of the after markets ones.

    Go on eBay and look for "4x4 posi-lock Chevy" you can find it there. :)

    Okay guy's help me out here. 1988 Chevy 1500 4x4 pick-up. Wouldnt go into 4 wheel drive. Found good info on this site,found bad switch on transfer case. By passed with a rocker switch and now the actuator / solenoid works. BUT....I cannot find a fuse for the 4 wheel drive. Should it be on the main fuse panel? What amp? Thermal or blade type. Just need to know, thanks in advance. Donno21 @ lyon_don@yahoo,com

    So I am hoping this appears at end of thread. Have a 1988 k1500 4x4 4wd not working. Have floor lights on at two wheel drive. front drive shaft is spinning when engaged, changed actuator and its extending with key on. Cheanges front diff. fluid no flakes. Also seems like low will engage somtimes? Tearing it down is out of my league.

    Any thoughts? I think rebuild is about 700? could it be just the internal fork . When I look in the hole with actuator out, rod looks pretty far in and I cant move it with pressure if that means anything. I think low is intermitant when I engage it some times I have to apply alot more brake pressue to keep truck stopped.

    Did you check the 4wd fuse inside truck panel..The trec or atc fuse in the Under hood Bussed Electrical Center (UBEC) fuse?


    Check the grounds on the frame under the drivers door?
    Also has the push button switch been checked? The solder joints for the connector on the circuit board in the switch are common on these... if you have a soldering iron..,, you can pop the switch out and re-solder the back side of the pins . Welcome to the forum.

    Got a lot of guys tagging in on this older post. It would be best if each of you start a new thread. In some cases, pictures also help if you have them.
