I have single sliding doors. Have same problem, cleaning didn’t work, lubricant didn’t work, adjustment didn’t work. I remove locking brackets, lifted them out. (Very heavy, but doable it strong enough) turned the on side. In my case the rollers were encased in lower frame removed the screws, Took my big rubber hammer and short 2x4, and tapped the bottom frame off. (Make sure you look at the adjusters If they are pegged out get the next size larger rollers. Usually starting at around 1 inch. That way If wrong rollers were installed you will have adjust ability.) disassembled the rollers out of brackets, replaced with new ones, ran adjuster screw all way down, Reassembled, clean track good, installed door, locks, and adjusted with screw at end of door that lifts doorframe off the tracks. Slide like they was on ice now. Good for another 20 years.
