Question is will they? Since the bulletin says to check for the rattle. GM stated the the shaft wear was as designed and only wore to a certain point and the debris was trapped where it wouldn't do any harm. Now they are saying that the debris can contaminate the bearings and cause them to fail. I would think they would change them all to prevent other engine damage if the bearings fail, but dont know if they will. I had no interest in changing my isolater out until this.
