Subaru WRX Center Diff Bearing Replacement and Viscous Coupling Rebuild

Center differential work done on my newly acquired ‘04 WRX. Bearings were shot in the transmission tail housing and needed replaced. I also rebuilt the viscous coupling, although I am not sure that it needed done. There is scattered info on the web on how to rebuild one, and I by no means claim to be an expert on the matter. So far, the car has driven fine and the rear wheels engage when the front begins to slip, giving me reason to believe my repair is not a failure yet.
