    Grounds have been checked, they are all good. When the actuator is plugged into the harness and installed I can feel it engaging when 4wd is selected.

    The model was exactly as I removed. It came from a rebuilder. The other day when I was working on this it did not seem like the actuator was engaging far enough. I proved this out tonight. I pulled the actuator and inserted a 3/4 inch socket in and then the actuator. Wheels did not turn in 2wd...

    Thanks for the diagnostic manuals much appreciated! I'll check it out. I will also check the power steering pump. Thanks. I already tried a new actuator, did not resolve issue. Should have a new tccm by Wednesday. I'll update afterwards.

    Maybe on older models but this has always had an electrical one. This is a 99. I will get another and try it.

    Yes I just tried, I was able to push the fork, it locked both wheels together. However the actuator does not appear to travel as far as I had to push in the screw driver. The actuator travel is only an inch. It's an electrical motorized actuator. The travel is set but a stop on the ram. I guess...

    I watched that video yesterday. Ok thanks guys, I will attempt that today. Maybe the actuator is not coming out far enough for engagement.

    BTW, those two wires appear to go to a missing abs unit that should mount on that bracket.
