How to install a torsion spring on garage door.
At this point you will wind the springs.
Just a video showing how to change out broken garage door torsion springs with new ones.
Otherwise replace both the left and right springs at the same time to save yourself from having to do the job twice.

Failure to install the torsion springs on the correct side will cause your door to function improperly and could result in serious injury.
