  27. See the accompanying illustration, and remove steering gear mounting bolts as follows:
    NOTE
    If the lower control arm bolt at the engine cradle has a lengthwise grooved shaft, it is a special wheel alignment adjustment bolt and the bolt head must not be rotated in the vehicle or damage to the bolt and engine cradle will result. While holding the bolt in place with a wrench, remove the nut, then slide the bolt out of the bushing and cradle taking note of bolt positioning in engine cradle for reassembly purposes. The bolt needs to be installed in the same position as removed to make sure wheel camber and caster return to adjusted position.



    Left side arm: Remove bolts (3) and (4). Loosen, but do not remove, bolt (2). It is important leave bolt (2) installed to avoid dropping gear too far, putting excessive force on steering coupling.
     
    Right side arm: Remove bolts (2) and (3). Loosen, but do not remove, bolt (4). It is important to leave bolt (4) installed to avoid dropping gear too far, putting excessive force on steering coupling.

  2.  
  3. Install nut on lower control arm cradle bolt, but do not tighten at this time.
    WARNING
    Before installing knuckle to lower control arm, measure height of ball joint seal boot mounted on knuckle. If seal boot height is above 25.5 mm, any air inside seal boot must be expelled. To do so, follow these steps:



    Tip ball joint stud completely to one side.
     
    Using thumb and index finger, gently squeeze seal boot together at center expelling any air. Do not allow grease to be release.
     
    Push down very top of seal boot.
     
    Return ball joint stud to original -centered- position.
     
    Measure ball joint seal boot height making sure it is within specification.
     
    Wipe any grease from ball joint stud.
