In my instance the replacement of the part in Sept this year has stopped the noise completely.
In my instance, Volvo identified the clicking to be coming from NSF Drive Shaft and they replaced part no VO36013244 axle shaft, which was the left axle. This was completed in early September this year and the clicking/flapping noise disappeared. I do still feel vibration when flooring it but I can't hear that same noise.
Pros: noise disappeared completely
Cons: still feel vibration
Vehicle:
Volvo
Part number: VO36013244
