Sliding closet doors keep coming off the track, how to fix

travel feedback.. mostly success...

on one bracket it was too far away from the track, and a big bump knocked that roller off (and tossed a lawn chair out the back of the TV bed!)

on another roller, the rough road bent the roller adjustment screw retainer so that the screw came out and the the space was to big..

but only twice over 3000 miles.. so a lot better.. these roller assemblies are just not up to the task is the net..
