I'm kinda curious as to how an inspection would reveal whether the shaft was properly heat treated. Don't they keep track of what parts go into which vehicle by VIN? They should be able to recall only those that have the defective part. I don't think someone shining a flashlight under my car is going to be able to reveal the absense of heat treatment.

I'm not looking forward to leaving my car at the dealership for a day or more. Hope the recall includes an alignment if they do have to remove and/or replace the shaft.
