Take a look at the track of your sliding door. Specifically look at the ends where it is undamaged, then follow it back and see the damaged flat spots, dents and splits. A damaged track will rip your door rollers. If you replace the door rollers, the damage to your tracks will wear them away. You need to permanently fix the track, or the maintenance costs will pile up.
