Hi all

I have a 97 UK S40 that has a wheel bearing type noise. its been to the doctors and they have checked it over 100% and can not find any sign of bearing fatuige. They have also checked the differential as well, so i am now at a complete loss.

What else could it be? It sounds like wheel bearing oscilation, and is most noticable between 40-70mph.

any ideas would be great

Cheers.

 

Do you know if they rotated the tires?Sometimes a bad tire can make the same noise as a wheel bearing.Try to rotate your tires and see what happens.

 

Hey Tech

Yes that has been done with no result. Looks like i'll have to change the rear 2 bearings for the sake of it, or turn the radio up louder. Thanks anyway

 

Try to see if it sounds like it is coming from one side more than the other and try replacing that one first and see if it gets better then maybe the other one as well.

 

Hi Viney,

Hope it's not too late and you haven't yet changed your wheel bearings! I have a 2001 S40 which recently had a problem, as I thought, with wheel bearing noise. On returning to the garage they assured me that it was road noise and I was still not happy with this, so took it back again and insisted it was not road noise. Eventually, they decided it was the four wheel alignment which cost them two tyres and eliminated the noise. Hope this helps you.

 

After all that, i gave up trying to locate the noise. Anyway, replaced the tyres last month, a nice set of DunlopSP1's thank you, and the noise has gone. So it was the tyres after all.

Thanks for alll the help.

 

Im glad it is fixed.
