    I bought a truck with a lift gate. It was real weak would barely go up and down. When I got it low enough I top it off with fluid but couldnt get it to go up. The solenoid is working the pump is going but doesnt seem to have enough power.

    I couldnt figure out how to pull the pump off. So I took the whole lift gate off. Now I kinda want to fix it and put it back on but dont know where to start.

    If I brought the whole lift gate to a alternator/starter rebuild place would they dissemble and rebuild the motor?

    Or could the problem be a piston or something else mechanical?

    Have yOu checked the fluid level you say pump is working, does it have something to pump?

    Yes i did. I had to lower it half way to access the pump and I filled it. Then when I got it all the way to the ground it wouldnt go up. I pretty much had to stand on it and hold the button down for it to move.

    Could be a couple of things. Weak battery, bad connections at battery or lift gate, bad power cable between battery and lift gate, bad motor, weak pump pressure or a bad ground.

    Get a new motor..
    Amazingly, they will run weakly until they finally die.

    Thats what I was thinking.


    Any idea how to remove it? It looks like this. This guy couldnt figure it out either and cut it out. That bolt in the middle is a valve.

    No bolts on the under side? Is it welded on? Otherwise, pry it off and replace. :laughing:

    I think the reservoir might be welded on. When i tried pulling thats the side that stayed put. If it is thats pretty stupid. How do they expect repairs to be made?
