OKAY I will measure the sway bar with a caliper and than I will check for the part.
And there is no knocking or rattle.
We do have a second Volvo, a 2003 V70 turbo, our son is driving this one. Last year it had a similar problem but my son brought the car to a different garage.(about 300km from here ...

Hi,
Our Mechanic told me buy to buy 2 SWAY BAR BUSHINGS the ones on the Frame.
Where can I get those Bushings? Is there a number for those?
For a 2001 S60 Base no turbo.
It will be okay to pay a few bucks because it is for our daughter's car.
Thank you so much for your help.

Gregor
