CAUTIONTurn air suspension (if equipped) off before hoisting, jacking or towing vehicle. Air suspension switch is located in right kick panel area. Failure to do so may result in unexpected inflation or deflation of air springs which may result in shifting of the vehicle.
  1. Raise and support the vehicle.
  2. Remove the cotter pins. Remove the castellated nut. Remove the steering sector shaft arm drag link. (Scheme 5)
  3. Use the special tool to separate the steering sector shaft arm drag link. (Scheme 6)
  4. Remove the steering idler arm and bracket bolts. Remove the steering idler arm and bracket. (Scheme 7)
  5. To install, reverse the removal procedure. The idler arm has two grease fittings. Lubricate with Premium Long-Life Grease XG-1-K or equivalent meeting Ford specification ESA-M1C75-B. Torque all fasteners to specification. See «TORQUE SPECIFICATIONS»(ref-96306-S15729173112001040700000).
