Condition
Some customers may comment on hearing a squeak, rattle or creak noise coming from
the second row/rear seat area. The right 40% seat is more prone to this condition,
however the left 60% seat could be affected.
Cause
The condition may be caused by either of the following:
4911773
Note: The “winking” is caused by excessive overlap of body panels and, as shown in the
graphic above, the sheet metal holes are offset. This is most commonly found at the right
rear fastener location of the right rear seat, or the left rear fastener of the left rear seat.
• Possible “winking” condition of right rear 40% seat floor pan outboard track rear bolt
hole, or the left rear 60% seat floor pan outboard track rear bolt hole.
• A seat track synchronization/torque condition that may require a torque sequencing of
the seat attachment bolts, on either seat.
Correction
Note: Perform the “winking” inspection and repair procedure as necessary first, prior to
performing the torque procedure.
For vehicles exhibiting the condition, follow the Service Procedure below to inspect for
and correct the winking condition, and also complete the torque sequencing procedure.

Service Procedure
5403437
1. Verify which rear seat exhibits the condition: the
right rear 40% seat (1) and/or the left rear 60%
seat (2).
Important: Follow the seat attachment bolts removal
sequence detailed in step # 2 below.
2. Remove the affected right (1) and/or left (2) rear
seat. Refer to Rear Seat Removal and Installation
(40%) and/or Rear Seat Removal and Installation
(60%) in SI.
2.1. Adjust the seat to full rearward position.
2.2. Loosen the outboard front attachment bolt,
then the inboard bolt.
2.3. Adjust the seat to full forward position.
Note: It is important that the tracks remain locked until
both rear bolts are re-torqued.
2.4. Ensure that both seat tracks are locked.
2.5. Loosen the outboard rear attachment bolt,
then the inboard bolt.
3. inspect the right outboard rear seat fastener
location of the right rear seat and/or the left
outboard rear seat fastener location of the left rear
seat for possible “winking” condition.

• If “winking” condition DOES exist, continue
ahead to step #4 and remove sheet metal
material.
Bulletin No.: 17-NA-384 August, 2021 Page 3
4911781
Note: In the graphic example above, the sheet metal is
still offset, but the nut is centered enough to avoid
contact of the seat bolt to the sheet metal.
• If “winking” condition DOES NOTexist, jump
ahead to step #6 and follow the torque
sequence procedure.
4911785
4. Using a dremel, or suitable tool, grind a small
amount of material from the floor sheet metal
opening. Grind only enough of the overlapping
metal to allow clearance for the seat bolt.
5. Use an air gun to blow out any metal debris in the
nut and hole area.
5403437
Important: Again, follow the seat attachment bolts
sequencing detailed in step #6 below.
6. Reinstall the removed rear seat. Refer to Rear
Seat Removal and Installation (40%) and/or Rear
Seat Removal and Installation (60%) in SI.
6.1. Ensure seat is in full forward position.
6.2. Ensure both seat tracks are locked evenly in
place.
6.3. Tighten the rear inboard bolt to specified
torque.
6.4. Tighten the rear outboard bolt to specified
torque.
6.5. Adjust the seat to full rearward position.
6.6. Ensure that both seat tracks are locked.
6.7. Tighten the front inboard bolt to specified
torque.
6.8. Tighten the front outboard bolt to specified
