Usually it does so by spinning the carrier bearings on the mounting hubs. In this case it was locked so tight that it sheared the hub on the ring side of the carrier. The car operated like this for about 8 years before the heat cycling finally got to the axle shaft and the left axle shaft sheared right at the gear next to the sheared carrier hub.

Tom, perhaps you can get a hold of one the new one piece axles Steve from Berts mentioned and let us know what you think.
