My steering seems to have a feeling like it is binding somewhat then seems to move suddenly. It doesnt do it all the time and only when I turn right. I have had an allignment and replaced the pitman arm, Idler arm and idler arm mounting bracket. I grease the front end every oil change(5000 Kms). I am starting to wonder if it is in the steering box and why it doesnt do it all the time. Ther is no apparrent play in any of the other steering, suspension components.
