My 2014 2.0 eb awd suddenly started making a loud clunk when turning either direction at low speed forward or reverse. Straight line or higher speed no vibrations no noise. It might be the half shaft CV joints but I have kind of ruled it out. The rear joints don't articulate when turning like the fronts. I placed a camera under the vehicle and can see the differential moving (jumping slightly) in accordance with the noise (Clunk). Seems to happen about twice per inside tire rotation. I have dealt with differentials in the past but I can't seem to find information about the guts of this thing. Do these have any type of traction aid, and is there a clutch or viscous coupling between the drive shaft and pinion? Has anyone experienced these symptoms before?
