I had taken my 04 2 to the local ex-Hummer dealership in town that told me the same thing regarding axle seals.

I now take the truck to a local mechanic who said the seal problem is basically across every 3/4 and 1 ton gm truck. The seals arn't really leaking as much as they are seeping slightly. If you look you should see some mositure on the axle around the seals, my mechanic told me they looked fine and it wasen't too necessary to rebuild them at the time (70k miles). He did say if I started to see a puddle of something after I've parked for a while that I should worry but the leaking seals is something he's seen on just about every GM truck that size.
