Thank you Lager for the references. As it turns out, I called a Volvo dealer who informed me that the bearing assembly is no longer available from the dealer. When it was available the the list price was $145 USD. So, I decided to pursue my Plan “B”. I pressed out the internal busing in a vice (it was in there very tight) and pressed it into a new replacement bearing that was only about $7 or so. In my car the failure of that bearing was the result of the whole A/C system going down. Given the task it is asked to perform, I’m surprised replacement of this small bearing isn’t a regular maintenance item.
