Have you checked the front subframe alignment? Could be out and causing this.

You need some aligment pins to check. To adjust, slacken off the subframe mounting bolts a bit and the then shift the subframe about until the pins go in.

Pic below of me doing exactly that.


Edit.....

Just noticed that it was the rear suspension that was renewed.

In that case, not sure. You might need some camber bolts on the back and or the alignment checked elsewhere.
