Hello. I’ve got a couple u-joints that I’m trying to model. The set up is a triangular yoke connected to two hanging arms with u-joints at the bottom and top of the arms. I’m using two hinge-joints at each u-joint connector.
The problem is that the right hinge comes apart at the axis of rotation slightly. It’s always the same hinge, but only happens when both left and right sides are active. If I deactivate the left hinge and let the system fall apart, the right one actually sticks together like it’s supposed to. As soon as I activate the left hinge again, the right one gets “loose” again.
Is there some priority things going on here? The settings are exactly the same for left and right sides. Can someone explain what’s going on here?
