Make sure you use the right lube if you do lube it. Most stores carry garage
door lube. I can't say why its special but I do know that regular lithium
grease doesnt work in cold weather ( found out the hardway).

I deposited a dab of lube every 4 inches on the screw and let the mechanism
distribute it around

My garage door makes it 1/3 of the way up and then begins to bind.
This is a screw drive opener. The rail between the opener and the
garage door, that holds the screw, begins to flex fairly seriously.
It appears this has bent the rail, and potentially the screw inside.
A neighbor told me he thought the screw just needed to be lubed. I
bought a tube of lube but am not real sure exactly *how* to lube the
screw. Do I just squirt the lube directly onto the screw for it's
full length? If the lube does not solve the problem, does the opener
need to be moved further away from the door or something like that?

Thank you for helping.
