After replacing the suspension there is a loud bang sound when driving over speed bumps?

I just changed my vehicle listed above suspension and now when going over speed bumps if I have any accelerator applied whilst going over it there is a loud bang on the front left corner it kind of sounds like the wheel is lifting off the ground gaining wheel speed and then touching the ground again which slows it down instantly causing the sound but I'm not sure how that could be happening as I just changed the suspension in an official Peugeot mechanic so I am not sure why or how the sound could be happening.

I would suggest taking it back to the shop and have the mechanic ride with you so you can let them hear the sound you hear. Without seeing it up close it sounds like a sway bar link or possibly it's hitting a bump stop. Could even be a half-shaft binding. Is the suspension still at stock height or was it lowered? Have seen lowered cars bottom out on bump stops before as well.
