How To Replace Worn Bottom Rollers On A Garage Door

Construction & Contractors Articles

If your garage door is noisy or opens and closes roughly, it is likely the rollers are bad. Garage door rollers, particularly those made from nylon, wear out after a few years of usage. The middle and top rollers are simple to replace, since you simply need to detach the hinges to which they are attached. However, the bottom rollers can be a bit trickier to replace, since they must be pulled free from their brackets. Below is a step-by-step guide to replacing worn-out bottom garage door rollers.

Tools and Materials You Will Need

  • Pair of replacement garage door rollers
  • 2 locking pliers
  • ½-inch steel bar or section of rebar, approximately 1 to 2 feet in length
  • Ball peen hammer
  • Long-handled flat blade screwdriver or pry bar
  • Stepladder

Step-by-Step Procedure for Replacement

1. Work with Safety as Your First Priority

Garage door work can be dangerous if you approach it with a cavalier or reckless attitude. The job of replacing worn rollers is safe, if you take a few safety precautions and work with vigilance and caution.

One of the main hazards of working with a garage door is unexpected movement of the door. That is why the first step is unplugging the opener and disconnecting the door's opener arm from the opener mechanism. The opener plugs into a nearby outlet, and you will probably need to use a stepladder to access it.

The garage door opener arm is attached to the opener trolley via a removable pin, so pull the pin and un-link the two components. Be sure to set the pin aside in a safe location where it won't be lost.

2. Spread the tracks slightly

To access the bottom door rollers, you will need to lift the door completely and bend the tracks slightly to pull the rollers free. Manually raise the door all the way, taking care not to pinch your fingers in the joints between sections.

Next, use a pair of locking pliers to grasp the front of the tracks approximately 2 feet above ground level, then firmly pull the front of the tracks forward to spread the gaps between the rail edges. Be sure not to bend the tracks completely out of position; all you need to do is create about an additional half inch of clearance for the rollers.

3. Position the door and lock it into position

Once you have spread the tracks, lower the door until the bottom rollers are aligned with the area that has been spread. Next, lock the door to the track by clamping one pair of locking pliers to the track above an adjacent roller and attaching the other locking pliers to the track immediately beneath the roller.

4. Pry the door from the tracks and replace the rollers

After the door is locked in place, use a long screwdriver or pry bar to pry the bottom of the garage door toward you, while standing on the inside of the garage, until the roller and its assembly pops out of the track. Grasp the end of the roller and pull it from the bracket; replace it by inserting a new roller. Repeat this step on the other side of the door to replace the opposite bottom roller.

5. Reinsert the rollers into the tracks

Finish the replacement by using the screwdriver or pry bar to maneuver the door back into position; you may need to apply some force to the front of the garage door with your hands in order to pop the rollers into position. Be careful that you don't get your fingers caught between the rollers and track.

6. Bend the tracks back into proper position

Once the bottom rollers have been replaced, the next step is to bend the tracks back into position. Remove the locking pliers from the adjacent roller and raise the door to its maximum height.

Next, insert a one to two-foot length of steel bar or rebar into the channel on the backside of the track where you previously bent it. Lock the bar into the channel using locking pliers on both ends.

Finally, use a ball peen hammer to hammer the steel track back into its normal configuration; the bar behind the track will help maintain rigidity and keep the track straight as you hammer. Repeat this process on the opposite track.

7. Restore the normal operation of the door

Once you have reshaped the tracks of the door, remove all locking pliers and reattach the door to the opener lever with the pin. Plug the opener back into its outlet and test the function of the door to ensure the new rollers don't catch or rub on the tracks.
