1. This hitch fits up to chassis panels under the vehicle in front of the bumper structure with the hitch
cross tube passing behind the spare tire well. Two reinforcing plates provided connect to the hitch side plates
and install inside the vehicle's trunk.
2. Remove the plastic sill plate and any flooring material in the rear of the tire well area exposing all metal
surfaces.
3. Lift the hitch into position on the vehicle with the driver and passenger side plates fitting to horizontal
chassis surfaces. A vertical body panel fits between the side plates on both the driver and passenger side of
the vehicle. Center the hitch on the vehicle and use the hitch as a template to mark and drill (4) 1/2" holes
through the chassis.
4. With the hitch removed, install rectangular U-bolts in the vehicle. Carefully lift the hitch in position over the
U-bolts and fasten the hitch in place.
5. Using the hitch as a template, drill (4) holes for 7/16" diameter carriage bolts through spare tire well. Inside
the spare tire well, position the CM-11823-BP plates with carriage bolts in the slotted holes passing through
the floor and hitch side plates. Fasten carriage bolts with hex nuts and lock washers as shown.
6. At the (4) round holes in CM-11823-BP plates, drill through the body panel for 3/8" diameter bolts. Install
3/8" fasteners as shown placing bolts from inside the vehicle. Handle nuts are placed outside the vehicle.
7. Torque all 3/8" fasteners to 45 lb-ft, and all 7/16" fasteners to 70 lb-ft.
