What year is your 9-5? The recall was for 9-3's due to a corrosion issue.
You posted in the "New" 9-5 forum, which is for the 2010 & 2011 cars, which are very close to still being within warranty. If this is the car you have, you should check with GM's service help line and a dealership before you start replacing things yourself.
