While making tight turns the transfer case would lock up into AWD and the whole front of the van would shake as the transfer case got bound up. This was due to an incorrect oil called for by GM. It would feel like there was something very seriously wrong with the vehicle the way it shook.
After looking on the internet I found GM service bulletins on the subject and they recommended a transfer case flush and fill. Instead of what was called for originally they now use AC Delco Auto Trak 2 transfer case oil. Which is blue in color. Note: This is for 99 and up only.
After a few driven miles the problem went away and the van now corners just like it should with no shaking in the front end.
