I jack my front tires off ground ,at lower control arm, checking out. Found some play pulling tire in 3 to 9. Tire rods are tight. Idler arm at drag link connection allows drag link to twist upward allowing some movement. If I jack up from chassis, suspension hanging, more movement is pronounced. Same at pittman arm, just not as bad. Truck has just over 100,000 miles. I am not original owner. How much movement can I have before issues? Also will supports be needed with my tires. I do pull my rv a lot too.
