Lift off over-whine

[alan996]

It's an odd one..

I bought a 12 plate AUC 40d E70 a few weeks ago..

I've noticed that if I lift off at about 50mph there is what I can best describe as a whine... It does change pitch with speed (but only slightly). It's there a little under acceleration I think

My gut feeling is/was its the new tyres on the car but I'm 1500 miles in now and it's still there...if I kick it into N it's still there. (Not sure of the transfer case is disengaged in N)

There is no clunking or shudder - but for a while it was pushing and pulling when on full.lock at low speed (unlike my 07 X5).

Suspicion is

A) tyres
B) wheel bearing
C) transfer box / X drive

It's AUC and it's not getting any worse - so no worries about a time bomb but I'd like to understand what it could be...

Just realized I posted it in the F15 section - can an admin move it to the E70 section?

Thanks
