I rotated the tyres. The sound stayed on the right hand side. I put the spare on and the sound didn’t change. Around 85km/hr speedo when you excellerate and or back off the sound goes louder Then at 100km/hr speedo the sound is very loud. I’ll change the bearing and see how we go.

Ahlem sorry I don’t understand counterweight the rotating mass?

Thanks guys for your help.
