I know my king pin bearings/kingpin are bad. i isolated them by removing the everything but the knuckle assembly and the upper knuckle/steering arm. There is definitely play. Other another post I found states that the arms: 54590 and 54591, have bearings already in place, so I wouldn't need to puchase bearings and press them into my existing arms. Is this accurate and correct info? Diagram
