You can get away with the push-pull steering, a lot of people did when Toyota's first came out with the 4x4's. But you also need to do some mods to the system if you are going to run it, J arm ball flip, dropped drag link and modify the torque arm mount the get the torque rod level to the ground. If you remove the torque arm or do not modify the mount you will get "brake steer" when you hit the brakes, it will pull to the right, the harder you hit the brakes the more it will pull. What happens is the axle rolls forward on the springs causing the draglink to push the "J" arm back, turning the wheels to the right.
"J" arms do break, especially if you hang the DS wheel in the air. Why, all the front-end weight is on the "J" arm and it snaps.
