2003 Chevy Duramax Ex Cab Automatic 4X2
My truck has a vibration that starts as soon as you touch 30MPH and lasts till 45MPH then goes away.
My tires look to be in decent shape.
What are the commong things i should look for to diagnose this problem.
Thanks, any advice would be greatly appreciated.

if mechanical checks out, have tires computer balanced. blisters, etc are not always visible but will show up on spin balance.

on ur 2003 had the drive shaft re balanced and this fixed the problem.
Tires were not the issue.

Put about 300-400lbs of weight in the rear and see if it goes away.

Did the truck just start vibrating or has it always vibrated? How long have you owned it?

Rotate the tires from front to back and see if the vibration changes. While it is up in the air give the front ones a wiggle up and down to see if the wheel bearings are toast.
