Be sure you grease your steering stops to before you pull the LBJ. New from the factory they have a rubbery plasic covering which wears off. When you compress the suspension at full lock you get a "horrible noise" from metal on metal contact. Grease remedies this.
If you you still need to replace you should be able to pull it by disconnecting the LBJ from the knuckle first then unbolting it from the lower A-arm. Beware the lower a arm is under spring pressure from the torsion bar. You might want to unwind them. I've done it without unwinding, but you need to be aware.
