Basically, you'll need to take off the pivot pin made of steel and the plastic or nylon cap and replace them with new ones.

Doors that are not aligned
A bifolding door is a fashionable feature for any home. However in time, it could develop issues that affect its ability to open or close. Fortunately, many of these issues are easy to fix and do not need the assistance of a professional.
The first step is to analyze the problem and determine the cause of your doors to misalign. You will require an instrument to measure the gap between the track of the door and the track. If you notice gaps that are larger at the top of the door than at the bottom then your doors aren't aligned. You can remedy this by loosening the pivot bracket's screw and shifting it to another slot on the bracket.
You may have to replace your pivot anchors or pins if you have doors that aren't aligned properly. They are typically made of wood and may be worn out over time. To replace the pins, you'll have to remove the doors and then remove the old pin with pliers or flathead screwdrivers. You'll then have to remove the pin that is damaged and then drill a new hole for it. If you are required, you will need to trim away the wood where the pin was damaged.
After replacing the pin, fix it to the door again and then mount it on its brackets. If the door is not seated correctly it is possible to shim it out by putting in additional wood or plastic. It is important to be aware that in the event that your door is out of alignment it may be more straightforward to replace it rather than shhim it.
If you hear a scratching sound when your doors open It's likely to be due to debris that has become lodged in the tracks. You'll need to get rid of the obstructions blocking the tracks, then apply lubrication. If the rattling is coming from inside the door, then the hinges or mechanisms have to be replaced. You should only rely on an established company to install your new doors.
