Is it all lubricated? Are any rollers seized or damaged, Is the track
properly adjusted - how does it jump out?? - does one side stick?

I'm not quite sure why it jumps out. The tracks do not appear to be
lubricated. It's always the same side that comes out, and the other
side always sticks on the track. Whatever it is, it's been very
poorly installed.
