    Default Packing a ball nut

    I had a spare ball nut laying around and I wanted to see what made it tick. Is there a specific method to getting them back in? Seems when I do it, the screw goes only in one direction.

    Do you have the type of nut with a cross over tube?
    This video would help.
    Sounds like you're missing some balls.

    Nope, I'm off for medical reasons for a while.
    Lots of free time sitting in front of the computer.

    There have been a couple folks repack them on here, IIRC they pried out one of the plastic plugs to reload the balls.

    You can't pry out the plastic plug, it has a lip on the inside. It is the return path for the bearings.
