The nuts that retain the rear passenger seat floor rail on the left hand side of the vehicle can be accessed from underneath the vehicle.

The right hand side rear passenger seat floor rails are similar, but require that the heat shields be removed for access to the floor rail nuts.

The 12 passenger extended van and the 15 passenger van reinforcements are used along with the rear seat floor rails. The reinforcements are installed on the underside of the vehicle to the floor rail studs, and held in place by the floor rail retaining nuts. If you remove the reinforcements, reinstall the reinforcements.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
