Whining Noise from Auris

[Oisin]

Hello,

My 2008 Auris 1.4 D-4D has been making a strange noise since I bought it 6 months ago.

When I am driving in 3rd, 4th or 5th gear, the car makes a whining noise.

It only makes the noise while my foot is on the accelerator, when cruising or accelerating.

The pitch of the noise changes with speed.

The noise stops if I take my foot off the accelerator.

I appreciate any advice.  Thanks!!

Hi Oisin.

It could be many things, wheel bearing, chipped tooth on the 3rd 4th gear in the gearbox, the diff. bearings and so on, can you record the noise and post it on here?

Hello and thanks for replying.

Listen to the audio clip I have uploaded.

You can just about hear the noise.

I should also note that this only happens in third gear between 30/40mph and it only happens in 4th/5th gear at 50mph+.  The pitch increases with speed and the sound fades out above 65mph.

The gears shift very smoothly and there is never any grinding.

There was new diff bearings put into this car recently because of wear and a new clutch kit also.

 

Any ideas what it might be?

Thanks

Hi Oisin.

It definitely is the 'drivetrain', that's the gearbox, final drive (Some call it the differential) or a wheel bearing. I know you have just had them  done but I think it a bearing and probably in the final drive, possibly it wasn't fitted carefully. If I were you find a decent transmission garage and let them diagnose and repair, that way if they mis-diagnose it then the mistake is down to them to sort out.

Good luck, Mike.

Thanks Mike.

 

I think I will do that.
