- Remove rear seat anchor covers and mounting bolts. Remove adjuster screw nut housing mounting bolt. (Scheme 4) Both adjuster screw nut housings mount to center of slider frame rail. Insert screwdriver blade between housing nut and rail. Lift and rotate housing nut. Slide seat back and remove front anchor nuts. Once seat is repaired, install housing nut bolts.
- Lift up front seat cushion cover to expose slide motor. Remove slide motor mounting bolts. If seat assembly cannot be moved forward, remove slide motor bracket mounting bolts. Move seat forward and remove rear anchor bolts. Once seat is repaired, install slide motor mounting bolts.
