    Thump from front end going over bumps, turning hard.

    I have been hearing thump noise from driver side front end and only when going over bump while turning right (entering drive way turning right).
    My steering feel has been a bit loose these days so I did quick slalom style test today and when transitioning hard from left and right, there is definitely a thump and I can feel suspension geometry getting out of orientation which felt scary!
    I have recently replaced both front control arms and control arm bushings so I wonder what it could be? Could it be due to components not torqued enough? I used torque wrench to the recommended settings but it was the first time using it.
    I would like to know what you guys think.
    Thanks!

    Could be the "top hat". Also check you end link. I had one come loose shortly after replacing struts and it was the cause of my similar clunk.
