I just bought a 97 blazer and I am getting road noise at the closure of the drivers side door and I can see daylight between the rubber seal and the door. What can be done to remedy this?

Your door hinge pins/bushings are likely shot.

Had the same problem with my 99. The door pins were shot causing it to sag.

i agree with swartlkk

I find that my door is sagging. How do you replace the pins and bushings.
