I have a few ideas, one being that the bottom pivot might be worn and is not holding the adjustment when it is set at the correct height. Another possibility would be that the pivot block 23-181 could also be worn and is not holding the location once it is set in the correct place in the track. Take a look at the parts that we've related for you to see if these parts could repair your doors. Thank you!
