Knocking from front end

[Black9]

Hi all. I have a 2015 aygo with 31k miles. Around 2m ago the front susp arm was replaced and alignment done. In the past few weeks the cars developed a knocking noise from the front and on acceleration pulls violently to the right and then to the left when I come off the accelerator.. I’ve had it looked at but the mechanic couldn’t find anything wrong. At times it feels like the front wheels about to fall off. I’m going to another garage this week and hope to find an answer. In the meantime, any indications to what it could be?

Could be inferior parts fitted or poor workmanship or both. You definitely need to check. 👍

Check the wheel nuts have been tightened properly.
