What to do if…
your wheelchair caster or wheel starts wobbling and you need to keep moving safely

What to do now

1. Slow down and simplify your path. Go straight, slow, and avoid sudden steering. If you must turn, turn wide and gently.
2. Get to a safe pause point. Aim for flat ground away from traffic, such as a building entry, lobby, storefront, transit station concourse, or level indoor area.
3. Stop and stabilize the chair. Set wheel locks or brakes if you have them. On a power chair, stop driving and power off if the chair feels unstable.
4. Do a quick check you can do without tools.
   • Look for hair, string, gravel, or other debris caught in or around the caster or wheel, and remove only what you can safely reach.
   • If you have quick-release rear wheels, check that they appear fully seated and latched. If you are not sure they are engaged, stop using the chair and get help.
   • If you have pneumatic tires and one seems soft, assume it may make the wobble worse and avoid distance until it is checked.
   • If you notice clicking, grinding, rubbing, looseness, or a wheel that does not sit straight, treat it as a repair issue.
5. Choose whether to move a very short distance or stop.
   • Stop moving and get help now if the wobble is strong, the chair pulls or veers, anything looks loose, the wheel rubs, you feel tipping risk, or you are near traffic or on a slope.
   • If the wobble is mild and you must move, move only slowly on flat ground to the nearest safer indoor space or staffed help point. Avoid ramps, curbs, uneven pavement, and tight turns.
6. Use nearby help without giving up control.
   • In a transit hub, mall, hospital, school, workplace, or venue, ask staff or security for a safe waiting area and help arranging accessible transport.
   • If someone helps you move, ask them to follow your pace and route. A helper beside you or spotting you may be safer than a fast push from behind.
   • If you are at immediate risk of serious injury, especially near traffic or on a slope, call 911.
7. Start the repair pathway once you are stable.
   • If your chair came through a durable medical equipment supplier, contact that supplier and describe it as a safety issue: wheel or caster wobble, possible looseness, pulling, rubbing, or vibration.
   • If you are followed by a wheelchair clinic, seating clinic, rehabilitation team, occupational therapist, or physical therapist, contact them for urgent guidance.
   • If Medicare is involved and you do not know the supplier or cannot reach them, use Medicare’s medical equipment supplier directory or Medicare’s official contact route to find an enrolled supplier.
