Load transfer error in static structural suspension simulation

  Hi,
  
  I have run into a 'Load transfer error' while trying to simulate my suspension model. I have tried turning off defeaturing entirely, as i have read this causes the issue, however this didn't work. I am totally at a loss as to what is causing this.
  
  I'm not sure if this would affect the issue, but I am running this in Ansys 2019 R3, however the CAD model was originally made in creo 3.0, and imported via an Ansys plugin into Ansys 19.2 (which i no longer have access to). A bit messy I know, but this is just the software set i have been given.
  
  Thanks for any help!

  Delete and recreate each part of the model: the two joints and the spring. That might help.

  Okay thank you, i will try that. i am using revolute joints connected to the inside cylindrical surfaces of the bolt holes... am i using these right?
  
  Edit: I have just tried what you suggested, and I am still receiving the same error. I also replaced the revolute joints with general joints free only in rotation along the z-axis. i also changed the main support of the trailing arm from cylindrical as i realised it needs to be able to move slightly in all directions.

  Check your mesh, there is a problem.
  
  If you don't need the stress, you can run this as a Rigid Dynamics analysis. See attached ANSYS 2020 R1 archive.
