Steering Issues after UCA install

Hey everyone, I recently installed bilstein 5100s and a new set of upper control arms. The install seemed to go pretty smoothly. But since then I've noticed that when turning my steering some times doesn't return to center like it used to, it almost favors either side and avoids center but usually when going higher speeds 45-65. Anyone have any idea what could cause this?

 

Probably super obvious question but you had it realigned after install right?

 

Your description points to negative caster.

 

Yeahhh.... so I had it aligned and it drives fine now, feel kind of stupid for it but just wanted to make sure I didnt screw anything up on install. Caster is a new concept for me. Thanks for your replies.
