Condition
Some customers may comment on unwanted seat movement in the front power bucket seat (driver or passenger) during fast acceleration or hard braking.
A metal to metal clicking noise is often heard at seat "stops."
Cause
The threads of the two zinc nut retainers (one on each side of the seat adjuster) may creep over time, causing a loss of self-rolling screw clamp load and
ultimately causes relative rail and vehicle seat motion.
Correction
Apply adhesive and install new bolts in seat mounting rails using the following procedure.
1.
Remove the front seat and invert onto a flat surface covered with a clean, non-scratch material (soft cloth or similar). Refer to the applicable Seats
sub-section in SI. Adjust so that the seat mounting rails are at 45 degrees.
2.
Remove the upper M8 mounting bolt from one rail and discard. Leave the other bolt intact as this will hold the track in place while working. Wipe
the bolt hole area with a clean rag.
Important:
Only use the adhesive provided in the repair kit. Do not substitute with other adhesives.
