Right Here at our Recalls/Service Bulletins Section
There are a couple others about the Steering unit. I know this is a problem, and someone that has changed out to a newer steering rack. GM does make a fix, so do a few of the aftermarket vendors. I think this is a problem all the way into the 1988 or 1989 Corvette.
