So I have put up with a front sliding door not sliding well (nor will lock from the inside) for a year or more. Just have not had the time to look at it. Finally this weekend I had an hour or two.
Figured this would be a big deal. Slide the door to the middle and grab both side and lift and just that easy it pops out of the bottom track! Carefully move it around and tip it over so I can look at the roller mechanism. I see two screws one which I see adjusts the roller in/out, the other I think?? locks it in place. So I adjust the roller out/down as much as possible and them "lock" it into position. Put the door back on the track and ka-bam it is working mucho better!! Even locks now!
I "found" two brand new (never used) spare rollers in the top of the door! This is so either hand can be used? So i have that ace in the hole.
I do have a question about all this. The bottom left joint (outside going in) seems to be pulling apart (1/8") but I could not get it to easily go back together. This would be why I had to use all my adjustment and why the door went bad.
How do these doors hold together? I did not spot this but figure it may have something to do with the second lock screw??
