Problem: Door wouldn't lock unless one side was lifted up. Doors not closing smoothly.
How to fix:
1. Read Jay's post on how to remove the door.
2. Loosen the tiny hex bolt on the bottom of the roller. This allows the roller to slide up and down the track.
3. Separate the bottom of the door frame from the window. Mine pulled right off. While I was trying to drill out the adjustment screw - that's a whole other post.
4. Slide the roller out.
5. Use a flat head
screwdriver to remove the pins on the brace holding the wheels.
6. Use a punchout to remove the pin holding the nylon wheel
7. Use a punchout to remove the steel bearings in the nylon wheel.
8. Soak the bearings in a cleaning
9. Soak the bearings in lubricant
10. Use plyers to force the bearings back into the nylon wheel.
- or if you have found nylon wheels use the new ones - if you find some let me know the measurements are: hole size 1/4 in, diameter 7/8 in, width 1/4 in
This was the closest I could find
... so far their customer service
hasn't returned my call - their pictures lack a view of the shape of the inside of the wheel.
11. Put it all back together
