Why Were Gen 1 AWD Systems so Delicate?

Tech Talk about Gen 1 Volvo AWD System

On the viscous system Volvo used: It was a good system and if the tires were rotated and no odd tires ended up in the mix it gave good service. Age on the VC has introduced some problems and baked grease in the front CV joint and middle support bearing failures are the service issues with age. And the splined connector sleeve wearing.

Gen 2 VC’s on the Volvo P2 models seemed to have been very low trouble and so far I’m not aware of those getting vibrations and other VC issues. I also do not see the VC on those sling out oil from midsection of the VC.
