My 2002 has the same leak fixed with cold weld just did it again today. This is the first new vehcle I've ever owned and the truck has been babied. A month ago I finally got her after the wife put 105k miles on her, we bought the wife a 2005 Z71 Suburban. Now I'm planning to trade the truck on a 2003 and this case leak is one of the reasons. I've heard this was only an iossue with the 01/02 trucks hopefully the 03 I found has the redesigned case.
