You have a simple question: how to repair a broken car door? then we have a answer to it.
If doors creak or from the slightest draught swing open are first sign of that in the house there is no skilful master. The rag which has been reeled up between handles, the slice of a skin somehow beaten on a jamb – not a way out. Meanwhile to correct a door not so it is difficult.
The door creaks. To get rid of a scratch, it is necessary to grease loops with lubricating oil from time to time.
Enclose under a door an edge of an axe or any other wedge, raise it on loops and start some drops of oil in the formed backlashes abouta pins of loops.
It is possible to use instead of oil slices of graphite from a soft simple pencil. Under weight of a door they will turn to a small powder, and graphite, you know, is a fine lubricant and serves long.
The door opens or is closed by itself. Means, loops are incorrectly attached: not strictly vertically, and hardly obliquely.
The door itself swings open. Means, it is inclined aside from a doorframe. Enclose under any of halves of the top loop a piece of a cardboard of the necessary thickness. Usually it happens enough that loops were levelled.
The door is closed spontaneously. Obviously, it is inclined to a doorframe. Put a cardboard piece under the bottom loop.

The door is got jammed. The most widespread at a rank – the become loose door loops. Replace screws with longer. It is possible to use and old, having strengthened their nests. For this purpose fill in apertures slices of a wire bast for ware or put wooden stoppers on glue.
Sometimes the door, is got jammed that the house has given
To deposit and the doorframe itself has bent, deformed.
Unique exit – to give doors an inclination corresponding to a frame. Enclose under one of loops about a laying as it is told above. If the bottom part of a door is got jammed, enclose a lining under the top loop, and on the contrary.
The door can be got jammed and that the backlash between it and a doorframe from outside loops is too great. In this case it is necessary to deepen nests for loops and to “drown” them a little. And if the door or a doorframe is warped enough to “drown” only that loop against which gets jammed.
When also it does not help, remove a layer of wood against that place where there is a jamming. As arrive and with the door which has inflated from dampness. Sometimes happens to process enough its end face a rasp or a rough skin, without removing from loops.
