My '08, extra cab, long bed, had the same problem with the trailer I still have. The '11 4 door does not. As in the problem is not model year specific. The dealer of course "could not duplicate" and did nothing.
I am curious to know what type of trucks are having this drive line shudder. I know that it appears that the drive shaft update seems to be fixing the issue.
If your truck has had the vibration fixed please post what the fix was and still mark the type above in the poll.
My crew cab long box has the issue if you accelerate hard on takeoff pulling a heavy load. I just don't take off hard and it hasn't been a problem to me . I installed Timberen overloads and it vertually eleminated the shudder.
My 05 crew cab long bed didn't have it but my new 2012 does. Both have camper packages. Sway bar on the 05 is way bigger than on the 2012. 05 has been lowered in the rear by 2" and still doesn't have the problem.
