Ok, been about 1300m and I've informed the dealer twice to check rear tire balance on the SE. They did so and can find nothing. Took it back in today and let THEM drive it and see if they feel the same shake I do.

Took a few minutes to replicate it of course but we did. Both service and tech drove it.

Symptom; at about 47mph you get a 'jiggle fest' happening in the cab that feels like a bad rear tire. Not balance but rather a blister or bubble. Glance at the mirror and watch the bed shake to the beat.

We took out another off the lot and it does the same thing! I have no clue and thought it a bad tire, but now we're stumped.

Am I the only one or do others have this??

I'm glad someone else has noticed this.  I'm willing to bet this is more prevalent than we know because it's often passed off as a bumpy road issue or some such.  My shake is at 50 mph and I suspect that it's some kinda harmonic vibration within the drive train.  Possibly due to the split drive shaft.

What really bums me about this is that my previous truck (a Chevy S-10 extended cab) had a similiar rear end shake problem that I chased for almost 2 years.  Did everything from new tires to multiple balancing to rebuilding/rebalancing the drive shafts to replacing the entire rear end.  The shake, or lack thereof, got better but never really went away.

I realize that I might be one of those folks that are very sensitive to vibrations or imbalances, but a vibration is a rotating mechanical device's way of telling you something's wrong.  And in the worst case, vibrational fatigue can lead to part failure.

I sure hope Titan Engineer or other Nissan folks are listening.

Well guys....I took my Titan in this morning for it's first service visit.  I've got around 10K miles and most of the items were nit-picky squeaks & rattles things.  However, my two biggest complaints were the shake issue and a gear whine noise.  Fortunately for me, the service writer (nice looking female I might add) owns a Titan just like mine so she was very familiar with all of my issues since her truck exhibits some of the same problems.  WHEW!  It's a comfort knowing I won't have to argue some of my complaints.  Anyhow.....

She told me that they had seen two other Titans, plus hers, that had this shake thing and had cured all three by eliminating the out of round tires with new tires.  That was good news.

Now the bad.  When we talked about the gear whine, she said hers had the same noise and it started shortly after they'd towed their ski boat.  She said she's got a new rear end on order for hers and she suspects they'll be ordering one for mine.

I have complete faith in both my dealer and Nissan that this will be made right for up until now, neither of them have given me any reason to think otherwise.  However, as a Mecahnical Engineer it just pisses me off to think that somebody, somewhere, didn't do their freakin' homework.   And if the culprit is Dana Corp., they ought to have their ass handed to them for they've been making gears & rear ends for everything from cars to heavy machinery to top fuel dragsters for years now.

Oh well - enough bitchin'.  I still love the truck.  You guys have a nice day.

     I had a similar shake at the same speed but it did not seem as violent as descibed above.  I could see the bed shaking and my passenger seat wobble a bit.  Once I added a pace edwards roll top cover, the problem stopped.  Maybe it is just wind for my problem.  I tried rolling up the cover and driving with the tailgate down.  The problem was gone as well.  Drove home with the tailgate up, started wobbling again.  Does not seem to be the same problem as others, but maybe you could try dropping the tailgate just to see if it helps locate the problem.
