What are you going to "lube" if not the rollers? "Lubing" the tracks
but not the roller bearings/axles will cause the rollers to tend to
slide, not roll just like putting your car on ice as opposed to dry
pavement. May give the symptom of rolling freely but not at all the
You may be "100% sure" there's nothing wrong w/ the door/rollers, but
I'm not convinced by any stretch...
imo, $0.02, ymmv, etc., etc., etc., ...
The tracks should not need lubricating.
Check the track itself -- is it "bumpy?" If so, you can get a stainless
steel replacement track that snaps on to the existing one (about $10.00).
'Course you have to remove the door (easy for two people - just lift up) to
install the replacement shim on the existing track. Before you snap the
replacement track in place, fill in the depressions with epoxy steel. While
you have the door out, check the rollers. They may simply need adjusting.
Are they meant to be oiled? These days many ball bearings are sealed for
life. It's possible that oiling them is just attracting dirt which is
causing the problem. It might be just cleaning you need not oil.
Lubing the tracks won't help because they don't slide on the tracks,
even if some call them sliders. They roll.
A lot of people have suggested removing the door. If you end up doing
that, you should know in advance that is very heavy and you have to
keep it from falling over on you, or away from you, and you have to
keep the bottom end from sliding away from you. Once it starts to do
that, you probably won't be able to stop it. You need something to
keep the bottom from moving away from you in the first place. The
fixed part of the door might work for that, but it has to be
accessible, and you have to first move the door to the side.
I removed my door alone because I had no choice, but it reqauired
planning and concentration. Having a second reasonably strong person
help you would help.
