Why does my hinge joint act like its connected by a spring? I want it to be locked

    So I have a hinge joint on an object that I want to be able to freely rotate about one axis but be completely locked from all other movement and rotation.
    I have also tried a configurable joint with everything set to locked other than one axis rotation yet it still moves, wobbles and rotates in all axis like its just connected by a weak spring

    Please help
    Thanks :)

    Here's the inspector of the object

    A possible cause is the difference of masses. PhysX expects the connected masses to be in a similar order of magnitude to produce strong joints.

    The masses are all set to 1 at this point :/
