Gents, XWD in great condition -all fluids Ben changed etc.
strange ‘whirring’ /very subtle ‘knocking ‘noise from front when accelerating through 30-40km/h that lasts a few seconds then stops —sometimes constant , other times intermittent.

Started shortly after 4 new tyres fitted/aligned but cannot see anything under the front that looks odd.

Any ideas greatly appreciated 👍
