I have a 2nd Gen 4WD V8 that started out with just a very light shudder under heavy acceleration. I went on a long trip and after several hours on the road, the vibration starting getting really bad. Felt like I was driving over rumble strips any time I pressed on the gas even a little bit. If I let off the gas, go downhill, or coast it goes away. I got the truck home and checked out the carrier bearing and I don't see any obvious problems, and the rubber around it looks ok.
I'm wondering where I should start looking, and what is the best way to isolate the cause. Is there a common component failure that causes this that I should check out first?
