    X-Type 2.5 AWD whistling noise????

    Hi folks,

    In this last couple of days my car has developed a strange whistling noise..............

    Every now and then, I hear this whistling. It sounds like something from an old horror movie, like the wind howling by. Very strange and a real mystery.
    I've read on here before about a whine that can eminate from the 'transfer box'. I've heard that in the past and it's never caused any problems, but this is very different.

    Anyone got any ideas???

    Cheers.

    sounds like the centre shaft bearing

    mine does it

    quite a high pitched noise

    i'm led to believe its happens more often when the weather is cold

    Thanks for that.
    Hmmm, could be something in that then.......... coincidence that it's just started this last 2 or 3 days since the weather has got really cold.

    Here as well, the last two days were -15 degrees centigrade and I got a bit of a whistle on motorway speeds, both when accelerating and when decelerating (engine brake). Not all the time, just occasionally. I've read up a few threads on similar issues, and typical suspects seem to be the centre shaft bearing and rear differential.

    Mine used to do this, but it's either cured itself or I just don't hear it anymore.

    Resonanting sound, only appeared at 60mph. Most likely the centre bearing. Not worried.

    I occasionally get the same too, common thing with the X-Type, centre shaft bearing whines, it's either put up with it, which is not threatening to the propshaft, or pay 600 for the joy of no noise from Jaguar.

    So this centre shaft seems the most likely cause!! Thanks for the info......

    I'm wondering if this will mean a visit to the dealer in future?
    I've had the car 2 years now, and it's been used in much lower temperatures (the first winter I had it it was driving in -15 and heard nothing) so maybe this is something that gets steadily worse. Where I am has only been -1 / -2 this last few days. Strange it starts happening now.

    Guess I'll see if it cures itself when the winter breaks. If not, maybe hand in the pocket again???

    Thanks all.

    Mine also does this, but as the others have said it is somewhat intermittent (and it's doing it at the moment despite a couple of 38 degree days).

    This weekend I'll try the centre bearing grease fix and I'll report back.

    Just to continue......

    Found some guidance on another Jag forum for greasing the centre bearing to try cure this whistling noise problem. See link:

    GREASING Propshaft Center Support Bearing (FAQ) - Jaguar Forums - Jaguar Enthusiasts Forum

    Had my car in my Father-in-Laws workshop yesterday.
    Jacked up and removed the two bolts from the centre bearing holding bracket. We spun the bearing by hand and all felt very smooth. So no damage or wear noted then.

    Instead of trying it the way noted on this other forum, we just applied a load of spray on grease around both sides of the bearing.
    For the rest of the day, hey presto - no whistling noise.

    I guess maybe a case of waiting to see how long this bit of spray on grease lasts, but so far so good it seems.

    This topic always crops up on the 4 wheel drive models when the temperature drops. I've had my 2.5 Estate for 4 years now and sometimes the whine is there and sometimes not in the winter. I've learned to live with it. It was worrying when I first heard it but there are so many threads on the website with various analysis. Come the spring, or warmer weather anyway and unless there is something seriously wrong, the noise will disappear.
