Lately, I noticed that my garage door wobble a lot when it open and close what is wrong? Are there anything I can do before call the expert?

The track that the door rides in is made up of several pieces. I would make sure that the screws that hold these various parts together are good and tight. Also, make sure that the brackets that attach the track to the house are secure. Finally, make sure that the little rollers are attached securely to the door.

I hope this helps,

I will do what you suggested, thank you.
