Pulls to the right sometimes

Hi, have a 2006 3.0 2wd coil spring ranger. Just replaced outer tie rods, upper control arms and lower ball joints. Got an alignment and now every once in a while when driving my truck pulls to the right. I do have some slop in my steering so that’s kinda what I’m leaning towards looking at next. Have you ever had this issue before? It seems like every once and a while the steering sticks to the right just a touch. Thanks.
