Thanks for the idea. So far Felder industries hasn't made a recommendation but if they/he does I'll follow it/them.
Rollers were replaced about 10 years ago. I guess that means time to check them...however that's done.
Many things are starting to be re-done and I was complaining about that until I realized I'd had the Syncro about 20 years. How'd that happen?

 Just follow Jim Felder's recommendations...

Maybe you will need new rollers too, because when they are worn the door
will sag and opening/closing the sliding door will be harder and harder...
