My spring broke very close to the end of the spring. Can I just throw away the part that broke off and reuse the rest of the old spring without having any problems?
: The remaining unbroken part of the spring should never be reused. Not only is the old spring fatigued for the full length of the spring and could easily break again at any moment, changing the length of the spring will also distort the lifting power of the spring and will not balance the weight of the garage door properly. Do not attempt to replace the spring yourself and have it changed by a qualified service technician.
