A garage door track that is out of alignment can cause the door to bind or rub against rubber molding. So, here is a quick how-to guide that will show you how to adjust the track.
Adjusting the Tracks for a Binding Garage Door
Step 1 - Loosen the Track Screws
If the garage doors bind or are hard to move up or down in the tracks, use a screwdriver to loosen the screws that secure the tracks to the garage door frame.
Step 2 - Adjust the Track Position
Gently tap the bottom of the track with the rubber mallet to position it correctly. Use the level to ensure that the track is perfectly straight (up and down) and that it is plumb.
Step 3 - Tighten Track Screws
Once the track is properly aligned, tighten the track screws so the track won't move.
Step 4 - Adjust Other Track
Repeat the process in steps 2 and 3 for adjusting the other door track.
Adjusting the Tracks for a Garage Door Rubbing Against Stop Molding or to Fix a Gap
Step 1 - Loosen Track Bolts
Use the wrench to loosen the track bolts that secure the tracks to the lower track brackets.
Step 2 - Adjust Door Gap
Move the tracks (left or right) so that there is only a small gap between the door and the stop molding. Usually, about a 1/4-inch gap is fine. Repeat for the opposite side of the garage door.
Step 3 - Tighten Track Bolts
Use the wrench to tightly secure the bolts.
