VW golf - rumbling noise

[Leanne1101]

Hi I was wondering if anyone can help. I have a golf 2L GT TDI 2005 and recently when going above 40mph I hear a rumbling noise, no blow on exhaust, wheel bearings have been checked, no noise when idling. Does anyone have any thoughts on what it could be?

Thanks

Can often be tyres - run your hand along the tread - if the blocks are serrated, it will cause a sound similar to worn wheel bearings

As said above, probably caused by abnormal wear on the rear tyres. Golf MK5s and other models based on the same platform are prone to this.

Do you have matching tyres? Any signs of unusual wear on any of them? Have you checked your tyre pressures?
