(Between Master Bedroom and Bath)
The door was squeaking when opening, so decided to lubricate it.
Stand in bedroom and take off left vertical trim. You might need to take off more trim to do this well.
At the bottom of the door, where the door leaves the pocket, is a metal piece which keeps the door from swinging. There should be one exposed nail which removes easily. Then push metal piece down to allow clearance so the bottom of the door can be swung into the Master Bedroom. Swing it a few inches into the Bedroom then go into the Bath and look above the door.
There is a 1/2 inch nut on each side, which really is an adjuster for the roller. Turn this counter clockwise about 3/4 turn to cause the roller to go up. Do the same for the other side.
Grab door and firmly lift it to get it out of the channel.
Reassemble in the reverse order.
I lubricated with 3 in one oil, but that may not be ideal.
