Top track wheel pops out when door closes

Hi,

I have a pretty old garage door system. I added the opener using the existing track door system. Every once in a while the wheel / roller that rides in the upper track pops out of the track. I can always get it back into the track. Recently this same wheel is popping out at the end of the cycle when the door is closing. The top track and wheel I believe is just for the top part of the garage door to close. It pops out of the track as it comes to the curved part of the track as it curves down to move the top part of the door closed. It is usually pretty easy to put it back in the track. I have to move the top part of the garage door and maneuver it back into the track. It might work several more times but then decide to pop out and cause the door to jam usually when I'm in a hurry to go somewhere...  

As the door opens I can see the end of the wheel's axle moving towards the track and back flush with the end of the frame in which it turns. When the door is opening, the axle starts to move in the direction away from the track and sticking out of the end of the frame in which it turns. When the track starts to curve downward, the wheel will pop out of the track. This is only happening with one track on one side. 

The track or door has never been hit or damaged. It seems to move fairly smoothly when opening and closing by hand. Although if opening manually there is more chance for the wheel to pop out. When the opener is pulling from the top center of the door it works better. Something has happened to affect the operation now.

I can take a video and / or pictures if it will help. Does this ring any bells as a common problem? Is this just an adjustment?

Thanks!

Is the track perfectly straight? From your description, it sounds like the track is crooked, at that curve. Although it seems unlikely that it'd just come loose by itself. What do the other wheels do when they pass that spot? Check the mounting at the wall, for movement. Maybe the wood? Is compromised where it's mounted to the wall, in the area where you notice the axle walking in/out especially. Watch the door for horizontal/vertical stability as it goes up, or down. Should stay steady, smooth, and level. No shifting side, to
side. Watch/Check the springs, drums, everything else visually, both with the door fixed, open, closed, and in motion. Check for a gap/daylight coming through one side of the bottom of the closed door. If you can find ANYTHING else that isn't quite right, that'd help diagnose this issue.

Just replace the top track on that side, quick & easy fix. Take a picture of the curve in the track. It will either be a 12” or 15” radius, I can tell you from the picture. Then once you know if it is a 12” or 15” radius, go to a local garage door company and ask them if they have a spare “12 inch radius, top track” they can sell you. Reasonable price should be $15-50, I’d give you an old one for free honestly. Most shops should have extra track laying around. Or just buy both left & right tops tracks & replace them both. It is a quick swap. Pictures would be nice to give you more precise info tho.

如果车库门系统上的轮子/滚轮不断从轨道中弹出，您可以采取以下几个步骤来排除故障并解决问题：

检查轨道：检查车库门轨道上是否有任何可能导致轮子/滚轮脱轨的障碍物或杂物。清除发现的所有杂物。
拧紧轨道支架：确保轨道支架牢固地固定在墙壁上。如果它们松动，请使用螺丝刀或扳手拧紧支架并确保它们牢固就位。
调整轨道对齐：使用水平仪检查轨道对齐情况。如果看起来未对准，请用橡皮锤轻轻敲击轨道以进行必要的调整。小心不要敲得太用力，否则可能会造成进一步的损坏。
检查轮子/滚轮：检查轮子/滚轮本身是否有任何损坏或磨损。如果它们磨损或损坏，可能需要更换。请参阅制造商的说明或联系专业人员以获取更换轮子/滚轮的指导。
润滑轨道：在轨道上涂抹少量润滑剂，例如硅胶喷雾或车库门润滑剂。这可以帮助轮子/滚轮在轨道上平稳滑动。
如果这些步骤不能解决问题，最好咨询专业的车库门技术人员以获得进一步的帮助。他们可以评估情况并在需要时提供适当的维修或更换。
