Removal Procedure

    Object Number: 161262 Size: SH
  1. Remove the nuts attaching the top of the strut assembly to the body.
  2. Raise the vehicle and support the frame with jack stands. Refer to Lifting and Jacking the Vehicle in General Information.
  3. Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation in Tires and Wheels.

    4. Notice: Whenever working near the drive axles, care must be taken to prevent inner tri-pot joints from being overextended. Overextension of the joint could result in separation of internal components which could go undetected and result in failure of the joint.

    Notice: Care should be taken to avoid scratching or cracking the spring coating when handling the front suspension coil spring. Damage can cause premature failure.

  4. Remove the Road Sensing Suspension position sensor from the lower control arm. If equipped
  5. Scribe the knuckle and strut. Refer to Strut and Knuckle Scribing .

    9. 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.
