No idea how old my wood doors are on my garage. They are in pretty good shape, but need some paint, and so Im looking to tune it up. They go up and down OK, but the doors do wobble a bit up and down, especially down. I had replaced the coil springs a few years back with quality US made parts.
Ive never messed with the rollers. I figured it was time.
They look like this:
So far, Ive tried flushing them out with WD-40. I figure its good because it creeps, it's cheap, and it will flash off. So I cleaned the big dirt, then sprayed WD-40, then wiped it all off and re-applied a few times each to try to get any dirt out. Ill let it dry from here.
Im thinking to work Corrosion-X in there for the long term. Not sure if that's the best, or what.
The tracks have some sort of black graphite-like substance. All of the wheels in the track roll smoothly, no issues there.
