SYMPTOM
When speeding up, slowing down, stopping, or turning, you hear or feel a noticeable clicking/popping from the driver's
and/or front passenger's seat-back. Clients sometimes compare this to someone kicking the back of the seat. This
sensation can also happen when adjusting the seat or shifting your weight in it.
POSSIBLE CAUSE
The plastic lumbar adjustment mechanism contacts the metal seat frame.
CORRECTIVE ACTION
Apply Kluber Centoplex 2 grease where the plastic lumbar adjustment mechanism contacts the metal seat frame.

REPAIR PROCEDURE
NOTE
Even if the noise is only coming from one seat, apply the repair to both seats.
Begin this procedure on the driver's seat.
1. Move the seat all the way forward and to its full height position. This will give you more room to work.
2. Use a mirror and flashlight to locate the two straps attached under the seat. Then, unclip the straps.

7. Measure out two penny-size dabs of Centoplex grease onto a clean piece of cardboard or paper.
