Worn rollers are the number one reason sliding doors stop sliding. Replacing them brings most doors back to a one-finger glide, at a fraction of the cost of a new door.
Steps
Get the right rollers
Measure the old ones first (see the measuring guide) or use the Roller Finder. Buy matching rollers before you start.
Remove the panel
Follow the panel removal guide with a helper. Lay it down on padding.
Take out the old rollers
Remove the screw at each bottom end of the panel, then slide or pry the roller housings out of their pockets.
Clean the pockets and the track
Clear out grit from the roller pockets and vacuum and wash the track while the panel is out.
Fit the new rollers
Slide them into the pockets the same way the old ones came out and refit the screws. Set them to their lowest height.
Rehang and adjust
Put the panel back, then raise the rollers evenly until the door rolls freely and the gap at the top is even.
Check the lock
Make sure the latch catches its keeper. Fine-tune the height if it does not.
See it
If the track rail is dented or worn into a groove, new rollers will still bump. A stainless track cap or rail repair may be needed too.
