Rear knocking noise ?? (Not RTABSor subframe ...)

Hello everyone,

About a two months ago , i had my RTABS replaced with m3 oe bushings because i searched around the forum for this problem.The mechanic said it was indeed the rtabs and my subframe was in perfect condition but he still suggested a reinforcement kit ..... now today , when i tried to reverse from my parking (goes up a bit to the street), it knocks a bit , from the rear left. Also knocks when i try to turn either left or right ?? It's not the transmission bushings because it only happens when i turn or take slight bumps. Heavy bumps will not make this noise. Has to be like a 80-90 degree turn i think.

Shocks are 1 year old bilsteins but i saw the end of the rear right spring broke off , can it cause this ? I am about to replace the springs with some h&r's.

The car still turns by itself toward left if i brake hard (But i replaced the RTABS !!)

Thank you for your suggestions everyone.
