My garage door makes a screeching sound when going up? I tried oiling the tracks but that doesn't help... Its coming from the third roller on the left side... but there seems to be nothing wrong with it. What do you suggest I should do with this roller because I want to fix this sound.

Thanks

The tracks aren't really where you want to lubricate, not oil. Grab yourself a can of wd40 or they make "garage door lubricants but its just the same thing just a little thicker". Don't spray the tracks, spray the roller stem where it meets the actual moving part. Spray either end of the roller moving it back and forth as you do (sometimes its easier to move them if you have the door an inch or two off the floor) hit both sides of the hinge where it meets and bends. If you do this once a year (they recommend every six months) to each hinge and also hit the pulleys if you have stretch springs or the bearings on either side of the tube if you have a tortion spring. Your door will last a lot longer and sound way better as well
