Lower Ball Joint

Print

INSPECTION



Replace the lower ball joint if there is any looseness in the joint or if the ball joint seal is damaged. Inspect the ball joint as follows:

  1. Raise and safely support the vehicle, allowing the front suspension to hang free.
  2.  
  3. Have an assistant grasp the tire at the top and bottom and move the top of the tire in and out. Check for any vertical movement of the knuckle relative to the lower control arm. If there is any movement, replace the ball joint.
  4.  
  5. Check the ball stud tightness in the knuckle boss by shaking the wheel and feeling for movement of the stud end or castellated nut at the knuckle boss. Check the torque of the castellated nut-a loose nut can indicate a bent stud or an enlarged hole in the knuckle boss. Replace a worn or damaged ball joint and/or knuckle.
  6.  
  7. If the ball stud is disconnected from the knuckle and looseness is detected, or if the ball stud can be twisted in it's socket using finger pressure, replace the ball joint.
