Steering Issue Maybe?

I am not even sure if this is an issue or not, but I thought I would throw it out there and see if anyone knows what I am talking about. I recently got a 2006 Uplander with the 3.5 AWD. When turning at slow speeds (like at a 4way stop) I feel a little slight vibration and hear a small noise when turning the corner. It is not very noticable, but I have not experienced this in my other vehicles. Is this normal? Is it a sign of a bigger problem on the way? Thanks for any tips or help.

It's probably one or more issues. There are TSBs issued for each. If noise is outside car it's usually steering gearbox. If sounds closer to steering wheel it's the shaft which has to be changed to new part number. Vibration during braking comes from warped rotors and on these cars is attributed to needing new dust shield design according to GM.
