Hi, I have this universal joint that works that I want to convert to ball type.

The joint description:

<joint name="forearm1_arm1" type="universal">
  <xyz>0 1 0</xyz>
  <xyz>1 0 0</xyz>
<pose> 0 0 0.17 0 0 0 </pose>


Now when I change it to type ball the joint becomes fixed.

<joint name="forearm1_arm1" type="ball">
<pose> 0 0 0.17 0 0 0 </pose> </joint>

There's no moveable axis after changing it to ball.

The ball joint has no indicated axi's. Another problem was causing them not to rotate.
