Drawer Track Replacement: Fixing Sticking, Sagging Drawers
A drawer that sticks halfway, drops at the front, or tips forward when you pull it out usually has worn or broken slides. Over time the rollers wear flat, the metal tracks bend, or the little plastic stops snap off. Replacing the slides restores smooth, level movement and keeps the drawer from falling out of the cabinet.
Drawer slides come in a few common types: simple two-piece roller slides found in older furniture, modern ball-bearing side-mount slides that pull out fully, and bottom-mount or center-mount slides. Replacement is mostly about matching the slide type, length, and mounting style to what the cabinet was built for, then setting both sides at exactly the same height so the drawer runs square. Even a small difference between left and right causes binding. Once the right slides are mounted level and parallel, the drawer should glide with a light touch.
How the job is done
- 1
Remove the drawer and inspect the slides
We pull the drawer out, often by depressing the release levers or lifting it off its rollers, and examine why it is failing.
- 2
Identify the slide type and length
We note whether the slides are roller, ball-bearing side-mount, or under-mount, and measure their length so the replacements fit the cabinet depth.
- 3
Remove the old hardware
The cabinet-side and drawer-side tracks are unscrewed, and old screw holes are checked so the new slides can anchor solidly.
- 4
Mount the cabinet-side tracks level
Each cabinet track is set at the same height front to back and screwed in, using a level so both sides match precisely.
- 5
Attach the drawer-side members
The matching tracks are fastened to the drawer sides at the correct position so they engage cleanly with the cabinet tracks.
- 6
Reinstall and align the drawer
The drawer is set back onto the slides and tested, with fine adjustments made so it sits level and centered in the opening.
- 7
Test full travel and the stop
We open and close the drawer fully several times to confirm smooth glide, even gaps, and that the stop keeps it from pulling all the way out.
What a pro checks
- Both slides must mount at the exact same height; a difference of even a fraction of an inch causes binding or a crooked drawer.
- Slide length should match the cabinet depth, since a too-long slide will not seat and a too-short one limits how far the drawer opens.
- Ball-bearing side-mount slides need a specific clearance on each side of the drawer box, which we account for when measuring.
- Stripped screw holes from the old hardware can be reinforced so the new slides hold firmly.
- Soft-close slides are an available upgrade that cushions the drawer as it closes if the cabinet has room for them.
- A drawer that tips forward when open often just needs slides with a proper out-stop rather than a whole cabinet repair.

Frequently asked questions
Why does my drawer keep falling off its track?
Usually the rollers or the stop have worn out, or the slides have bent so the drawer no longer stays engaged. Fresh slides with a working out-stop fix it.
Can you upgrade my old roller slides to smoother ones?
Often yes. Many cabinets can be retrofitted with ball-bearing or soft-close slides as long as there is room for the new hardware. We measure to confirm before recommending an upgrade.
Do both slides need replacing if only one is broken?
We generally replace them in matched pairs so both sides run at the same resistance and height. Mixing a new slide with a worn one usually leads to binding.
What does drawer slide replacement cost?
It depends on the slide type, the number of drawers, and any repairs to the drawer box. Request a quote and AZ Smart Fix can give you a price after a quick look.
