Crestline sliding doors

It sounds like a problem with the rollers. You should try cleaning the track and adjusting them and see if that works. If not, you should consider replacing them altogether. Watch the video below for more information on how to replace patio glass door rollers.

Without seeing pictures of the original rollers, it will be hard to make a recommendation. However, Crestline used two types of rollers back then. You may have one of these.

If you have am adjusting screw on the face of the bottom rail, it could be our 81-018. If the adjusting screw is on the bottom end of the door, however, then consider our 81-166 instead. That said, we highly recommend confirming before you make a purchase, as we cannot guarantee that either is a match.

The only way to know for sure is to remove your roller from the door and compare it to our 81-018. I think that may be it, but I cannot guarantee it.
