New Thrust Arms, New Wheel Shake

[BigBody]

Hey everyone, was hoping i could get some insight into a problem i am having. I have recently replaced my thrust arms in my 05 4.4. This tremendously improved a shake i was having in the steering. The car is a 1 owner (my dads) and i dont know when the last time the suspension/bushings have been replaced but im sure its been a while. Im having a new problem now a couple hundred miles later. The wheel has a slight shake when going into a turn at high speed, ie. on the highway.. Also today, i noticed the car seems to pull right at higher speeds. I dont believe the brakes or rotors are the culprit as the car brakes fine when driving straight. Im going to bring the car to my mech and have him diagnose the issue. Im thinking the problem may be related to the unchanged control arms. Anyway, wanted to share my symptoms and see if anyone can chime in.. Thanks again and have a happy 4th!
