How to Replace Garage Door Vertical Tracks - DDM Garage Doors Blog

Replacing damaged garage door tracks is important because the tracks hold the door in the opening and keep it from falling. Failure to replace the tracks can also cause premature wear to rollers, hinges, and cables.

In this video, we explain how to replace the vertical tracks on a garage door.


In order to replace your vertical tracks, you will need a power drill, a screwdriver, and replacement track parts.

  1. Before removing the old track, raise the door above the junction where the vertical section meets the upper section.

Installing the Track

  1. Once you have drilled the holes, line the track up against the track angle.
  2. Install the bolts from the inside of the track, and use the nuts to secure the bolts from the outside.
    1. Start with a bolt at the top and bottom, loosely tightened.
    2. Then, install the bolts in between.

Testing the Door

  1. Once they are tightened completely, close and open the door to test the fit of the track. If the wheels will not turn, that means the track is bolted too closely to the rollers.
