I'm bringing my R into Keystone Berwyn on Wednesday to fix the power steering fluid reservoir and have them look at the AWD system. Is there a magic word I need to say to get the right techs to work on my car? You seem to know folks there.<p>The AWD started to fail sometime in March, I think the collar gear connection was failing based on the noise it made and the front wheels spinning, back wheels not moving on a shallow incline and snow. Since then I think it works sometimes, hard to tell, but I prefer to have them replace the collar gear now if it means not needing to replace the angle gear later. I'd like to try the new collar gear option, and I'm not under warranty, do you think they would go for it?
