    1.2. Install the J 21474-19 bolt through the J 29376-A plate and into the receiver.
    1.3. Install the bushing on the bolt and position into the housing. Align the bushing installer arrow with the arrow on the receiver for proper indexing of the bushing. A high-pressure lubricant such as J 23444-A may be necessary for assembly.

    1.5. Press the bushing into the control arm by turning the bolt. When the bushing is in the proper position, the end flange will be flush against the face of the control arm.

    Important: The washer and nut must be installed on the outboard side.

  3. Align the control arm and the underbody attachment.
  4. Loosely install the bolt, the washer, and the nut.
  5. Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
