blacklock

I recently had death wobble and replace the ball joints, draglink, trackbar bushing and bolts also did polyurethane sway bar bushing. Death wobble is gone so far. I installed synergy ball joints and their drag link. Also got it aligned afterwards. I have no lift all stock 08 JKU. Now it seems like my steering is loose or not reacting to the wheel when turned. I can turn the wheel and it seems like nothing happens then sometimes like a slight turn causes it to over steer. Kind of like I am driving on ice and turn the wheel and sometimes it goes the way I want sometimes it doesn't. It not drastic but is enough I notice it. Any ideas what this could be. Should I go back to stock draglink could that be the problem?
