Hi,<br>My car has developed a drivetrain whine over the past two days. It is most noticible at approx 45-50 mph on part throttle (very light throttle). Its pitch increases with speed and is audible in 3rd gear thru 6th. To me it sounds like rear diff whine. I can also bearly hear a screeching noise - like light brake screech but again it appears to be coming from the drive train.<br>The car is 2006 and has 60k miles done. Have looked at back diff and can see no oil leaks.<br>Any ideas ?<p>Sean

Re: Drive train whine that changes with speed (sdowdeng)

Angle gear is going. Could last a year before major malfunction occur or it can go tomorrow.<br>Mine again also started to whine last weekend. this last one doesn't even has 10K done <IMG NAME="icon" SRC="http://www.vortexmediagroup.com/images/banghead.gif" BORDER="0"> <br>my previous one whined for aprrox. half a year and 5000km before 3 teeth broke.

Re: Drive train whine that changes with speed (JARMO)

Is the angle gear at the back of the car ? As this seems to be where noise is coming from ?<br>Sean

Re: Drive train whine that changes with speed (JRL)

I'd guess a wheel bearing, too, based on your symptoms.

None of the tree wheel bearing failures I have had exhibited noise that changed pitch.

Go around a regular street corner, left and right, with some throttle, to test wheel bearings.<p>Also check underneath the car to make sure nothing is rubbing up against the AWD shaft. You never know.<p>When my rear wheel bearings went, it didn't sound like a whine, it sounded like tire road noise.

Re: Drive train whine that changes with speed (S60R1)

Hi <br>It is definately a whine.....I've heard a similar noise before from the back end of trucks - but with lower pitch. <br>Dont hear any thing with wondows down (except low level screech).<p>I though 2006 cars have update angle gear ?<p>Sean

Re: Drive train whine that changes with speed (sdowdeng)

I had a similar sound under those conditions which was remedied with two new rear hubs, so +1 on the bearings idea. <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0">

See if the noise gets better or worse as you turn. Even when cruising at the speed which makes the most noise turn slightly as to put weight on the right, then the left. If the noise gets worse one way and much quieter the other then it's most likely the wheel bearing.<p>Without even listening to it i'd say wheel bearing. Just my opinion.<p>But if you want change the angle gear.
