Rear subframe/mount problem, cant do alignment

Hi Guys
I try to figure out what should be course of action in my case, I have Prius 3 japan version, front suspension 100% condition but there is quiet yet frustrating knocking coming from rear left, passenger side when driving on uneven road, and more road noise, front is quiet.

When driving, car pull slightly to right when steering wheel is straight, when I brake, steering wheel is turning left, is not in centre, on flat road etc, not much but still is noticeable, I bought 2 new front tires and done alignment, front is perfect but I found that rear left is not straight on diagram(please see pic)


My question is if I should change only subframe mounts, if that will fix rear alignment or if I should change whole subframe because is bented? I went to one mechanic but he didnt found any cracks on mounts but car have 108k miles at the moment, please let me know what you think about this.

Regards
Daniel

 

maybe with previous owner in japan, as right front lamp is new, rear looks untouched

 

I have 4 new shocks, and most of front suspension is new, new links, new top strut mounting on rear and front, I only didnt changed rear subframe and rear subframe bushings
