Click, Hum, Squeak: What Your Wheelchair's Noises Are Trying to Tell You
Every regular on my bench announces itself before it breaks. Owners rarely notice β the sound arrives so gradually it becomes the chair's new normal. Then a bearing seizes on a Tuesday and a two-minute fix has become a two-hundred-dollar one.
You don't need a mechanic's ear. You need ten quiet minutes and this short map.
Clicks: mostly innocent, one exception
A single soft click when you power on, and one when the electromagnetic brake releases β that's healthy machinery talking. A repeating click-click-click while driving, though, especially in turns, usually means something loose is finding something to hit: a fender bolt, a chain guard, a control box bracket. Find it by hand before it finds your wiring.
Hums: location is everything
Electric motors hum; that's their accent. A hum that's always been there, unchanged, steady with speed β fine. The ones that earn attention: a hum that gets louder on slopes (motor working harder than it should β check tire pressure and brake drag), a hum at standstill with the joystick centered (a controller or motor phase issue β bring it in), and a new buzz from the charger that didn't buzz before.
Squeaks: the cheapest problem you'll ever fix
Squeaks are friction asking for a drop of oil: folding joints, seat pivots, suspension springs. Ten minutes with silicone spray, twice a year, and they stay quiet. Squeaks never become catastrophes β they're just annoyingly honest.
Grinding: stop driving
A grinding or gravelly feel through the frame is the one sound with no innocent explanation. It's metal on metal, or a bearing eating itself, or gears stripped. Every kilometer driven on a grind multiplies the bill. Stop, call service, and if you must move, walk the chair in freewheel mode.
Clunks: one per bump, or one out of nowhere?
A clunk synced to bumps is suspension doing its job loudly β check for a loose spring seat. A clunk when you change direction, though, is play somewhere it shouldn't be: motor mount, gearbox, or a folding lock that's worn past its tolerance. Those need a torque wrench and eyes, soon.
The two-week listening habit
Once every couple of weeks, drive a slow lap on a quiet floor β garage, empty hallway β phone flashlight off, ears open. New sound, old sound getting braver, something that clicks only left-turning: that lap is how you catch the two-dollar problem while it's still two dollars.
Heard something this list didn't cover? Record ten seconds of it β a video with sound helps us enormously β and send it over. We service every wheelchair we build and plenty we didn't.
