Do these symptoms sound like DTCactuator motor fail?

My car has had the DTC triad for a couple months now but I have had this symptom for even longer. it started as choppy acceleration when starting out while turning and then progressing to this clunking noise when making slow turns that I had assumed was a suspension issue. I changed most of the front suspension and it remains.

When making a turn at low speed, if I am not giving it gas at the time ( think pulling into a spot) I will get a terrible clunk clunk clunk from what seems to be the front dif or the transfer case. it seems higly dependent on the steering angle with more angle being worse up to a point. Even if I push in the clutch while making the slow turn it still makes the noise.
However, if I cut power to the car while making the turn by hitting the start button, as soon as the engine cuts out the car smoothly continues through the turn without any noises or vibrations.

I am already in serious trouble with this car so this issue is giving me a lot of anxiety. Does this sound like it could be the stripped worm gear? Or is it something else entirely.
