Pretty basic, but have you checked for loose wheel nuts?
Driving back from the coast this weekend I noticed a new noise/vibration. It seems to be coming through the steering column. Only comes in around 90KPH on the overrun or at constant speed on the flat.
Its not like unbalanced wheels or a steering wobble, just like metal on metal vibrations at a reasonably fast frequency.
Any ideas?

What tyres do you have?
I have something similar at 95 - 100 km/h on smooth bitumen.
Pretty sure it is my tyres GG AT's.

						Lotz-a is yours a 2.7?
My previous D4 (2011 2.7) had the same sort of thing, only felt through the steering wheel, and at about 85km/h under gentle acceleration.
I never noticed it until about 10,000ks. But then it was always there, particulary on one part of the daily commute.
But my new 3.0L does not.
Have a 3.0 SDV6 and it's not the tyres, this is a new noise never had before, almost like a dry bearing.

						SupporterDon't be so sure about your tyres. If you have AT tyres it almost certainly is your tyres. It only happens as they wear. There is never any vibration when they are new. If you put OEM Wrangler tyres on you will see that the vibration disappears.

Have had dealer fitted GG AT's on the car since I've had it and know the noise of the tyres. Sometimes makes you think you've got diff noise.
This one is quite different, sort of like a small dry roller bearing spinning a few hundred RPM when actually attached to the steering column.
It will annoy the business out of me till its identified.

One way to check if it is the tyres is to swap front to rear, rear to front. The axles wear differently so you should get a different effect if it is the tyres, that is unless you had them rotated recently/regularly.

						SupporterI am not talking about the normal tyre whine or the normal tyre vibration. As the tyres wear you get a different noise and vibration exactly as you have described. Pitty you haven't got the original tyres. It is very easy to check whether it is tyres or something else when you can easily swap to the OEM tyres.
There have been several recent posts on this topic and some older ones also where people are getting similar issues to what you have described, some with GG tyres. With my old Continental Cross Contact tyres, which were very quiet for a long time, I had the same thing after about a year (30,000km) and I was really scared my wheel bearings had seized or something similar. Put the OEM tyres on and no vibration at all. My D697's after about 30,000km are now just starting to exhibit the same sort of behaviour, although not as bad as the Contis. The silly thing is that there is also nothing visible on the tyres that would indicate that such a vibration could occur.
As I said, don't discount the tyres so readily.
