The first step for rear door lock installation involves replacing the door lock connecting part packing with new material unless reusing a previously removed door lock while maintaining a clean surface condition without grease or dirt on the packing material. For the front door lock apply MP grease to all sliding and rotating components followed by installing the rear door inside locking cable which requires pressing in the three claws to secure the cover. The next stage requires installation of the rear door lock remote control cable during which you should engage the claw followed by closing the cover. A new door lock wire harness seal should be positioned on the rear door lock before placing it into the rear door outside handle release plate and fixing it to the rear door panel while ensuring the rear door outside handle frames lock into place. Place Toyota Genuine Adhesive 1324, Three Bond 1324 or equivalent on screws' threads before tightening the rear door lock with 3 screws using a "TORX" T30 socket wrench to 5.0 Nm (51 kgf-cm, 44 in-lbf). Connect the connector, then proceed to install the rear door window regulator sub-assembly, rear door glass sub-assembly, rear door quarter window
Weather Strip, rear door window division bar sub-assembly, rear door glass run, rear door belt moulding assembly, rear door Weather Strip, rear door check assembly, rear door service hole cover, rear door trim bracket, rear door glass inner Weather Strip, rear door trim board sub-assembly, rear door inside handle bezel, and rear door armrest base upper panel. Attach the cable to the negative battery terminal while tightening it to 5.4 Nm (55 kgf-cm, 48 in-lbf).
