Fold down the 40 side rear seat back, remove the arm rest bolt and then get rid of the retaining C clip to remove the arm rest. Removing the rear seat back first helps you reach and take out the silencer panel fastener screws located behind it, before you remove the silencer panel. Then, after removing the screws that hold the arm rest to the back of the seat, remove the arm rest. Slide the 60/40 armrest assembly into the bracket, install the bolt and tighten it fully to 12 N.m (9 ft.lbs.) after that, attach the C-clip and move the seats back in their place. To install the rear ski/pass, set the arm rest and bolt it to the seat back with fasteners tightened at 5 N.m (45 in.lbs.) torque, replace the silencer fasteners and mount the seat back.
