Deville and Fleetwood
  1. Raise and safely support the vehicle, allowing the front suspension to hang free.
  2.  
  3. Remove the wheel and tire assembly.
  4.  


WARNING
Be careful when working in the area of the CV-joint boot. Damage to the boot could result in eventual CV-joint failure. If necessary, install CV-joint boot protector tool J-34754 or equivalent, to protect the boot.

  1. Remove the stabilizer bar-to-control arm bolt.
  2.  
  3. Remove the cotter pin and nut from the ball joint stud. Use ball joint separator tool J-36226 or equivalents, to separate the ball joint from the steering knuckle.
  4.  


WARNING
When working near the halfshafts, be careful not to overextend the inner CV-joints. If the joint is overextended, the internal components may separate resulting in joint failure.

  1. Remove the control arm mounting bolts and remove the control arm from the frame.
  2.  

To install:

  1. Position the control arm to the frame and install the mounting bolts, washers and nuts. Do not tighten the mounting nuts at this time.

  5. Connect the ball joint to the steering knuckle and install the castellated nut. Tighten the ball joint nut to 88 inch lbs. (10 Nm). Then tighten the nut an additional 120°, during which a torque of 41 ft. lbs. (55 Nm) must be obtained.
  6.  
  7. Install a new cotter pin in the ball joint stud. If the cotter pin cannot be installed because the hole in the stud does not align with a nut castellation, tighten the nut up to an additional 60° to allow for installation. NEVER loosen the nut to provide for cotter pin installation.
  8.  
  9. If necessary, remove the CV-joint boot protector tools.

Then tighten the nut an additional 120°, during which a minimum torque of 37 ft. lbs. (50 Nm) must be obtained. If the minimum torque is not obtained, check for stripped threads. If the threads are okay, replace the ball joint and knuckle.
  4.  
  5. Install a new cotter pin in the ball joint stud. If the cotter pin cannot be installed because the hole in the stud does not align with a nut castellation, tighten the nut up to an additional 60° to allow for installation. NEVER loosen the nut to provide for cotter pin installation.
