Worn rollers
Flat or wobbly rollers bump along the track.

Noise and hardware
Shaking or jerking during travel usually means something is dragging, loose or out of balance. Worn rollers, loose hinges, bent tracks, a slack opener chain or weak springs are common culprits.
Short answer
Watch the door from inside as it opens. If it shakes at one spot, look for a track or roller issue there. If it shakes all the way, worn rollers, loose hardware or an unbalanced door are more likely. Tighten accessible hinge screws, but leave springs and cables to a technician.
Flat or wobbly rollers bump along the track.
Loose fasteners let panels move and vibrate.
Bends or loose brackets cause jerky travel. See track repair.
Weak springs or a slack chain make the opener pull unevenly.
Shaking usually develops gradually, so owners often get used to it. Comparing the door with a neighbor's, or filming it from inside, can show how much it has changed. A door that shakes more each month is telling you that rollers, hinges or balance are getting worse, and the opener is absorbing that extra strain every cycle.
Describe what the door is doing when you call. A provider may ask follow-up questions, but a reliable price normally needs an on-site look rather than a phone-only quote.

Most residential doors have between eight and fourteen rollers, depending on height and design.

Over time, hinges loosen, rollers dry out and the opener's settings drift as parts wear.

Vertical tracks run up each side of the opening and curve into horizontal tracks under the ceiling.
Worn rollers, loose hinges, a slack opener chain or an unbalanced door are common causes. A tune-up often addresses several at once.
Yes. A door that drags or bounces makes the opener work harder and wears its gears and motor.
Not always, but severe shaking or binding can lead to derailment. Have it checked if it is getting worse.
If worn rollers are the cause, new rollers often make a big difference. The technician checks tracks and hinges too.
Yes. A loose chain can jerk the trolley, making the door move unevenly. Adjusting tension usually helps.
Look for loose hinge screws, wobbly rollers and visible track bends. Leave springs and cables to the technician.
