Default Help…Thumping Noise front end

Hi all, I have a Rx350 2007 model with 286,000 kms on the clock, it’s making what sounds like a thumping noise coming from the front end, it’s had all the wheels, tyres and front wheel bearings recently replaced. The mechanic advised me that the thumping noise is not coming from any of the suspension components, but either from the front differential or the transmission. The differential diagnosis sounds correct as it gets louder when taking corners. Has anyone had this issue before?

It sounds like it might be coming from a from a front CV Joint!
When a CV Joint starts going bad, it makes an audible noise when turning corners!
Just an Idea!
