I have a little over 1,000 miles on my truck and have been experiencing this low tone drone in the cab with the engine running at warm idle. It will do this in Park or with the brake held in Drive. It almost sounds like an aftermarket exhaust drone on a Mustang and really gets in my head. I took it in to the dealer for service, and they realigned the exhaust. It did not remove the drone. We started up another new truck on the dealer lot, and it displayed the same drone. To my knowledge, my previous 2011 did not do this. Anyone else noticed and/or found a fix for this?

 

This kind of stuff is really hard to deal with. I know that my truck has a nice strong vibration and hum from the motor but it's a fact with diesels that they emit a good strong and steady hum and vibration unlike any gas motor.

The diesel engine has a unique feel to it so it is important to get the obvious out of the way, are you used to it? Is this your first diesel? Don't be offended, but we are talking about the quietest and smoothest diesel ever in a pickup and like I said, got to get past the obvious part to see what you are talking about.

 

I can't think of an intelligent way to say this but I wonder if this low vibration noise is something we notice more because of how quiet this engine is?
With the 6.0L, the rest of the engine was so loud and things did vibrate but maybe we couldn't necessarily hear these low, deeper noises as clearly.
I didn’t own a 6.0L but was around a ’05 and a ’07 enough to have a basic understanding of the sounds, features, etc.

A diesel is expected to be louder and it doesn’t bother me at all but know exactly what someone is referencing when the low rumble is brought up.
I describe this 6.7L idle as a rumble vs the loud well-known clatter.
This one clatters more with age but you have to listen for it.

Difficult to type into words for some reason.
Return to your scheduled programming.

 

I have heard what Kper05 contends before and it makes sense to me. I will be giving up my 6.0 for the 2012 in a week and will see if I have that experience. Can't wait to find out.

 

I cannot hear any hum or drone over the sound of how awesome my 6.7L is LOL

 

I have the same drone in mine. It gets a little stronger when I accelerate slowly but goes away when I hit about 5 MPH. I actually like the sound. Quite a few friends have also positively commented on it.

 

It's out already?

 

Low speed engine lugging causes the middle inside part of my dash to rattle so it drowns out any other noises.
Not worth it to me to have the dealer tear my dash out and risk other issues.
Edit: I don't spend much time at that low driveway speed; not where 400 HP shines...lol.

 

I wouldn't like that either. The drone I like but if I also had the vibration I would be trying to get rid of it.

 

opps, jumped the gun a little. It's a pre-order..............
