The ball joints are arranged such that if the upper ball joint is to be removed, the lower ball joint must be removed first. Conversely, the upper ball joint must be installed first, before the lower ball joint. Failure to install the upper ball joint before the lower, will result in a lack of clearance for the installation tool.

  1. Remove the steering knuckle.
  2.  
  3. Place knuckle in vise and remove snapring from bottom ball joint socket if so equipped.
  4.  
  5. Assemble the C-frame, T74P-4635-C, forcing screw, D79T-3010-AE and ball joint remover T83T-3050-A or equivalent on the lower ball joint.
  6.  
  7. Turn forcing screw clockwise until the lower ball joint is removed from the steering knuckle.
  8.  
  9. Repeat the previous steps for the upper ball joint.
  10.  

Always remove the lower ball joint first
To install:
  1. Clean the steering knuckle bore and insert lower ball joint in knuckle as straight as possible. The lower ball joint doesn't have a cotter pin hole in the stud.
  2.  
  3. Assemble the C-frame, T74P-4635-C, forcing screw, D790T-3010-AE, ball joint installer, T83T-3050-A and receiver cup T80T-3010-A3 or equivalent tools, to install the upper ball joint.
  4.  
  5. Turn the forcing screw clockwise until the upper ball joint is firmly seated.
  6.  

If the ball joint cannot be installed to the proper depth, realignment of the receiver cup and ball joint installer will be necessary.

  1. Repeat the previous steps for the upper ball joint. Install the snapring on the lower ball joint.
  2.  
  3. Install the steering knuckle.
  4.  

Mountaineer, 1995-99 Explorer and 1998-99 Ranger

The ball joints on the Mountaineer, 1995-99 Explorer and 1998-99 Ranger are integral with the control arm. If the ball joint is defective, the entire control arm must be replaced. Refer to the appropriate control arm removal and installation procedures later in the section.
