HD sells silicone spray though I have been told by others that
Silicone can attack bearings.
I have also seen White Lithium grease and spray along with other types
What do you folks recommend?
Also what about spray vs. grease gun vs. squeeze tube vs. manual
application with rag?
Wd 40 is crap for chain and bearings. My door is apx 70 yrs old ,
grease packed in the bearings and oil on the chain and door hinges,
thats it every few years for the bearings and twice a year for the chain
and hinges, and it is then quiet. But honestly I forget so its more like
every 5 yrs or when I notice noise.
I wouldn't lubricate the tracks at all. Just lube the bearings with some WD
40. The wheels move so slowly through the tracks that it would hardly
benefit to lube them. Also, consider what type of drive you have -- long
screw drive or chain -- and lubricate the chain or screw.
In fact, it's harmful. If you lube either the wheels or the tracks, the wheels
will slide in the tracks some of the time instead of rolling. This will, in
time, create flat spots on the wheels, and then they won't roll at all.

Nobody ever left footprints in the sands of time by sitting on his butt.
And who wants to leave buttprints in the sands of time?
I've found after cleaning them out, just coat eveything with a thin
layer of motor oil(new stuff), works well.
Too much goog, and you are inviting heavy dirt build up and binding.

WD 40 does little, as it is not a lubricant, but primarily a rust
I use household oil to put a drop or two into the wheel ball bearings - they
need almost no lubing, and tracks should be kept clean and dry..
For the rest of the door moving parts, hardware stores sell an 8 or 12 oz
tube of white silicone grease made for garage door screw drives as well as
chain drives. It is stable over larger temp. ranges than lithium automotive
grease (any auto supply store), but probably works just about as well. I
also use the silicone grease to finger into the pivot hinges. Since I
started doing that, the squeaks don't return for years at a stretch, vs
light oil or wd40.
Just a word of warning. Don't grease the screw (assuming it's screw drive)
with a lot of grease.
Too much grease and the motor won't be able to turn the screw. I didn't
know this and ended up
having to remove the grease I put in there.
