Recently I have noticed a vibration and different sound to my Duramax truck. I have noticed the vibration is especially bad at speeds between 45 to 55 mph. I can't see anything loose under the truck. I can also feel under my feet while driving. The sound of the truck that I was used to has also changed. What do you think is wrong? I thought about changing the u joints but not sure if that will fix it. What do you think?
