I replace GM door bushing alot. Most of the reason for doing it is lack of lubercation. They should be lubed every oil change, but no one does it. Much of the wind noise is from the door being caught in the WIND. That springs the door, very common. I just did a 03 Full size truck Monday that had this problem.
To make your door fit tighter, it seems that moving the latch inward on the bottom of the ext door always helps.
Glueing the weather strip in is a No,no. They are not glues from the fatcory, they pinch onto the body. Just sqeeze the channel back togeather and reinstall.
Good Luck.
