I have a overhead door on my barn. I have one roller that is squealing, I think it is dragging. Is it worth fixing, or should I just let it squeak?
Keep the springs an bearings oiled.
Also keep in mind, it is never a good idea economically to just replace one spring. (Unless your moving the next day).
Springs are not that expensive. You can avoid the inconvenience of having the second one break, and having to pay a second service call, usually a short time later, if you just replace both of them and get it over with.
You can also usually upgrade your springs from the standard 10k cycles, to 20k or more, for only a nominal charge.
Having spent most of my life as a painter, I would love to see silicone lubricants banned from the face of the earth. They are an extreme contaminate that is nearly impossible to eliminate for painting. So, your fixing one problem, and creating another.
