My 2006 Toyota Corolla hit a curb recently. I had to replace the lower control arm and various suspension components. Now when turning there is a popping sound as you turn the steering wheel. I disconnected the outer tie rod end from the knuckle on the accident side so the only things moving are the steering wheel, rack, and the opposite tire. The sound is still there which leads me to believe its the rack. Could it be something in the steering shaft? How do I isolate further?
