INSPECTION



If an inspection of the lower ball joint on one side of the car indicates that replacement is necessary, it is recommended that the lower ball joint on the other side also be replaced.

1962-67 Chevy II
  1. Fabricate a support for the upper control arm according to the dimensions shown in the illustration. With the car resting on its wheels, install this support between the upper control arm and the frame side member.
  2.  
  3. Remove the cotter pin and nut from the lower ball joint stud. Disconnect the stud from the steering knuckle.
  4.  
  5. Fit the nut to the lower ball joint stud. Using a torque wrench, measure the torque required to rotate the lower ball joint stud. The specified value for a new lower ball joint is 4-8 ft lbs for 1962-65 models, or 9 ft lbs for 1965-67 models. If the torque required is excessively higher or lower than the specified value, the ball joint should be replaced.
