Lower Hinge, Rear

Starting the replacement of rear side door upper and lower hinges requires that you switch off the ignition and take out the key because it prevents SIR from deploying while maintaining safety. Use soft marker pen to mark the location where the hinges will be installed afterward you apply support to the door. First thoroughly secure the door in place on the striker then consecutively detach the hinge to door bolts and later the hinge to body bolts while maintaining careful work with single hinges at a time. Install the hinge to the vehicle structure based on pre-removal marking positions. Fasten the hinge to door bolts at 25 Nm (18 lb ft) torque followed by hitching the hinge to body bolts and tightening them to 36 Nm (27 lb ft). The door needs inspection for proper alignment before completion.

The task to replace rear side door upper hinge and lower hinge requires switching off ignition and taking out the key to stop SIR deployment and personal injury incidents. Trace around the hinge position with a soft marking pen while supporting the door. To replace the rear side door upper hinge and lower hinge begin by fully latching the door on its striker and proceed to remove both hinge to door bolts and hinge to body bolts while maintaining one-by-one removal of components. You need to install the hinge on the vehicle by using the marks which were created when you took out the components. Insert and tighten the hinge to door bolts to 25 Nm (18 lb ft) before adding the hinge to body bolts which require a torque of 36 Nm (27 lb ft). The final step consists of verifying that the door sits in the correct position.

Align the hinge to the door, install the bolts, and tighten the hinge to door bolts to 33 Nm (24 lb ft).

Adjust the door, ensuring that striker alignment is correct to avoid damage to the door latch and striker.

Remove the hinge to body bolts and the hinge to door bolts.

After removing the door support, install the fender sound insulator.

Replace only one hinge at a time, then repeat the procedure for the second hinge if necessary.

Avoid striking the door or the door pillar near the side impact sensor (SIS), and ensure the ignition is turned OFF with the key removed during service in that area.

Begin by marking around the hinge location with a soft marker for installation alignment.
