Yes. If you don't feel it in the wheel, it probably isn't the tires or the suspension.shirleyujest said:I will keep you posted. Thanks.
You know, I thought it might be a bad set of tires.. but when I suggested that to the dealership, they just look at me funny. :teeth:
Although, if it was the tires, perhaps I would feel it in the steering wheel?

I have noticed a vibration (sound) throughout the cabin at speeds between 50 and 65 mph. It is more of a "seat of the pants" variety. In otherwords, I do not feel it the steering wheel, but rather it is more of an overall vibration of the entire cab. .

I get a noise that you can also hear and feel at about 60-65 mph on the highway under very light throttle. If I release the throttle or push it furhter the noise /feel goes away. I think it is worse with body on frame vehicles.
That's one "characteristic" I'm glad my Armada doesn't have. Mine is smooth as glass, with the factory wheels and tires. I guess I got lucky, because I know many have had problems with the OEM tires.shirleyujest said:I just got a call from the dealership. And the story they told me was that it is a characteristic of the vehicle.
They drove other Armadas, and they have the same "problem".
They also checked out the TSB regarding "cabin boom" and was told by the techline that the problem was fixed for '05.
When I pick up the car, I am going to drive another Armada to see if this is correct.
Honestly, the problem isn't super annoying...but it is annoying none the less.

Whats the symptoms of vibration of a drive shaft?ChuckD said:Generaly speaking.. out of round or balance tires on the front will be felt in the steering wheel. If you feel vibes in the seat or chassis it will be the rear wheels or driveline.
You could try rotating tires around to see if your symtoms change and if it is a tire or tires then moving them might help you isolate the problematic tire.
Or as 92TripleBlack suggested... take the Armada to a good tire shop that has a Hunter GSP 9000 tire balancer. This system will find the wheel/tire combo that is giving you grief if there actually is one. If it is a tire, they may be able to rotate the high spot on the tire to a low spot on the wheel and correct an out of round issue. This does not work too well if your wheels are extremely true... but most wheels ,OEM and aftermarket, are not extremly true anyway.
Another thought is that it could be that your driveshaft is out of balance. It could have tossed one of the balancing weights stuck to it's side.
[Edit] By rotating the tires I meant simply swapping wheel positions not dismounting the tires etc.. This might be a DIY if you have access to a couple of jacks. I always try things on my own first since going in for service sometimes can be frustrating.
Also.. sucesss with the GSP 9000 is highly operator dependant. Sometimes it can take 30 minutes or longer per wheel for the operator to find the wheel/tire sweet spot. Make sure you find a place who knows how to operate it well. AND.. sometimes the tire after some use can slip back out of the sweet spot and start vibrating again. More often than not this does not happen, but it is a posibility. So if they do find an out of round tire.. and since the truck is so new.. I would insist the dealer swap it out with a good one.
