DIAGNOSIS

  1. With the vehicle cold-soaked and the ambient temperature at 23º F or below, drive the vehicle over a road with small bumps.
    • If a pop or clunk (similar to a mallet hitting a solid metal piece) is heard from the front struts, park the vehicle inside the shop and wait about 30 minutes to warm it up, then continue with step 2.
    • If no noise is heard, this bulletin does not apply. Continue with normal troubleshooting.
  2. After the suspension components have warmed up for 30 minutes, drive the vehicle on the same portion of the road where you heard the pop or clunk.
    • If there is no noise from the front suspension, continue to REPAIR PROCEDURE.
    • If the same noise is heard, this bulletin does not apply. Continue with normal troubleshooting.

 

REPAIR PROCEDURE

  1. Raise and support the vehicle.
  2. Remove the front wheel.
  3. Remove the wire guide rubber and the clip from the damper. Do not disconnect the wheel speed sensor connector.

wire guide rubber

 

  1. Remove the brake hose bracket from the damper.
  2. Remove the flange nut while holding the joint pin with a hex wrench, and disconnect the stabilizer link from the damper.

stabilizer link

 

  1. Remove the damper pinch bolts and flange nuts from the damper.

NOTE: Do not allow the knuckle to rotate too far outward, or the driveshaft inboard joint may come apart.

damper pinch bolts

 

  1. Remove the cowl top wiper cover, then remove the flange nuts from the top of the damper. Do not let the damper/spring drop down under its own weight.

flange nuts

 

  1. Remove the damper/spring.

damper/spring

 

  1. Compress the damper spring, then remove the self-locking nut while holding the damper shaft with a hex wrench. Do not compress the damper spring more than necessary to remove the self-locking nut.

Compress the damper spring

 

  1. Release the pressure from the strut spring compressor, then disassemble the damper.
  2. Install the new bump stop.
  3. Reassemble the damper using a new self-locking nut. Torque the nut to 70 N∙m (52 lb-ft).
  4. Reinstall the damper assembly onto the vehicle using the new flange nuts and pinch bolts. Torque the flange nuts to 69 N∙m (51 lb-ft) and the pinch bolts to 175 N∙m (129 lb-ft).
  5. Reconnect the stabilizer link to the damper. Torque the bolt to 79 N∙m (58 lb-ft).
  6. Install the brake hose bracket to the damper. Torque the bolt to 21 N∙m (15 lb-ft).
  7. Repeat steps 2 through 15 on the other damper assembly.
  8. Do the front wheel alignment.
