The Causes Of Side Mirror Vibration

Before we delve into the fixes, it’s important to understand the underlying causes of side mirror vibration. This knowledge will help you diagnose the issue more accurately and apply the appropriate solution.

Wind Resistance:

At higher speeds, air resistance can cause vibrations in your side mirrors. This is especially common in older or poorly designed vehicles.

Loose Mounting:

Over time, the mounting hardware that holds the side mirror in place can become loose. This is often the culprit behind mirror vibrations.

Mirror Glass Damage:

A cracked or damaged mirror glass can create vibrations due to irregular aerodynamics.

Vibrations from the Road:

Rough road conditions and uneven surfaces can transmit vibrations to the side mirrors, making them shake.

Electrical Malfunctions:

Modern vehicles with power-operated mirrors can experience vibration if there’s an issue with the mirror’s electric motor.

Now that we’ve identified the potential causes, let’s move on to the steps to fix side mirror vibration.

Easy Ways To Fix Side Mirror Vibration

1. Tighten Mounting Hardware:

  • Start by locating the mounting hardware behind the side mirror’s cover. This may require removing the cover, which can often be done by carefully prying it off.
  • Inspect the screws, nuts, or bolts that hold the mirror in place. If any of them are loose, tighten them using the appropriate tools.
  • Be cautious not to overtighten, as this can lead to new issues. Aim for a snug fit without applying excessive force.

2. Replace Damaged Mirror Glass:

  • If the mirror glass is cracked, chipped, or otherwise damaged, it’s essential to replace it. You can typically find replacement mirror glass at your local auto parts store or online.
  • Carefully remove the old mirror glass by gently prying it off the backing plate. Then, attach the new mirror glass securely.

3. Add Vibration Dampeners:

  • To reduce the effects of wind resistance and road vibrations, consider adding vibration dampeners to the back of the mirror housing.
  • These can be found as aftermarket products and are often made from materials like rubber or foam. They help absorb vibrations and stabilize the mirror.

4. Check Electrical Connections:

  • If your side mirrors are power-operated, inspect the electrical connections. Loose or damaged wiring can lead to mirror vibration.
  • Carefully remove the mirror switch panel and check the connections. Ensure that all wiring is intact and properly connected.

5. Replace the Mirror:

  • If none of the above solutions work, or if the mirror itself is damaged, you may need to replace the entire side mirror assembly. This is often a straightforward task, and replacement mirrors can be found for most makes and models.
