In most cases the rear door is damaged as a result of an accident. If the damage is vast enough to prevent the door from closing and opening, it should be replaced with a new one. Replacing the rear door is a time-consuming procedure. It requires disassembling and reassembling all panels and the window lifting mechanism. In addition, you have to make sure that the door is aligned with the car's body, so that it works properly and looks good.
How is the front door removed?
Car door removal is quite complicated. First, you have to remove the trim panels. Before you get down to it, make sure you know how they are fitted not to damage the plastic clips and grips holding them to the door - you wont them to fit back in exactly the same place later on, so that they don't produce any annoying sounds.
What else has to be done?
After removing the trim panels unplug the electrical cables inside the door. Depending on the car version, you may have to disconnect the window motor, the central lock, the side view mirrors motor, etc. Next, you have to remove the door stopper. Finally, you can remove the bolts holding the door to the hinges. Don't forget to support the door, e.g. by means of a wooden block, in order to prevent it from falling down in an uncontrolled manner. A good idea is to have someone help you. In order to facilitate fitting the door back in place, mark the position of the bolts relative to the hinges. After you have taken the hinge bolts out, you can remove the door.
How is the side door fitted?
The side door is fitted in the reverse order. After pre-tightening the bolts, make sure that the door is in the same position as originally. To do this, look at the marks you have made. Also make sure that the door closes easily without rubbing against any of the neighbouring elements, such as the pillar or the sill. After tightening the bolts, close the door gently to make sure that it fits properly.
What to keep in mind?
The only thing left to do at this point is reconnect all the electrical cables. A good idea is to spray the plugs with a special agent to ensure a better connection. After fitting the stopper and the trip panel back on, apply grease on the working surfaces of the hinges and the stopper.
