front noise when driving on uneven roads

Hello guys this morning i've been to toyota to do the regular service and to try to find that what is creating this noise on my front end ,they removed brackets etc and lube antiroll bar bushes and top mounts as best possible .......still the noise is there .....we recreated the noise this morning by circling around at full lock multiple times . they said that if the lube would not solve the problem it could be the struts mounts??? About £400 to replace them ,I made this video yesterday night in the car park were u can ear the noise ever time the wheel goes on top of a small pot hole ,what do u think?thanx

Prius gen 3 front noise:

i did find a better video on youtube with exactly the same noise
please guys what do you think
