    M62tu engine vibration/ drone

    Hi. Iím in the UK and have just joined this forum to see if anyone can shed light on a problem I have with an engine..
    First let me say that I own an L320 supercharged so these forums may prove to be useful in the future..

    Anyway, the engine in question is in my BMW X5 - the M62tu 4.4 which was also used in Range Rovers.
    The problem it has is a drone / buzzing vibration and harshness at about 1700rpm when under medium load. Itís recently had a trans overhaul with torque converter etc so I donít think itís that.
    I came across a post by a member on here (who I have pmd) and he described a very similar symptom on his engine and he mentioned Ďauxiliary drive belt droneí.
    Is this such a thing? Can anyone shed any light on my engines problem?
    Thanks.

    I had a vibration in my car under medium load. Ended up being the centre universal joint and mount of my rear driveshaft.

    I have an L322 with the M62 and canít say Iíve had the problem. I wonder if itís a failing fan belt.

    Try also asking on British forum fullfatrr.com

    BTW, you have an L322, not an L320 which is an RR Sport. Probably just a typo - we all make them.

    Thanks for the replies.
    Incorrect - I do have an L320. Itís a 2005 Range Rover Sport 4.2

    Anyway, back to the vibration. I donít think itís the centre support bearing as it only does it at a certain rpm. I have checked it and it seems ok to me. I could be wrong though.

    Aha! I misread the post. I missed that the question was about your X5, not your Rangie which might explain why I didnít understand the auxiliary belt reference, the L322 only has a single serpentine belt for the fan and ancillaries.
