How do you know which motor mount is bad?
Motor mounts are essential components of your vehicle, designed to secure the engine to the chassis while minimizing vibrations and noise. Over time, these mounts can wear out or fail, leading to noticeable symptoms that can affect your driving experience. In this article, we’ll explore how to identify a bad motor mount and what steps you can take to address the issue.
What Are Motor Mounts and Why Are They Important?
Motor mounts, also known as engine mounts, are typically made of metal and rubber. Their primary function is to hold the engine in place and absorb vibrations caused by the engine's operation. A failing motor mount can lead to excessive engine movement, increased vibrations, and even damage to other components of your vehicle.
Signs of a Bad Motor Mount
Here are some common symptoms that may indicate a motor mount is failing:
- Excessive Vibrations: If you feel unusual vibrations in the cabin, especially when idling, it could be due to a worn-out motor mount.
- Clunking or Banging Noises: A bad motor mount can cause the engine to shift excessively, leading to clunking or banging sounds when accelerating, braking, or turning.
- Engine Movement: Open the hood and have someone rev the engine while the car is in park. If you notice the engine moving excessively, it’s a clear sign of a bad motor mount.
- Uneven Engine Alignment: A failing motor mount may cause the engine to sit unevenly or tilt to one side.
- Increased Wear on Other Components: A bad motor mount can put extra stress on hoses, belts, and other engine components, leading to premature wear.
How to Diagnose Which Motor Mount Is Bad
Determining which motor mount is bad requires a systematic approach. Here’s how you can diagnose the issue:
- Visual Inspection: Start by visually inspecting all motor mounts for cracks, tears, or signs of wear in the rubber components. Look for any metal parts that appear bent or damaged.
- Engine Movement Test: With the vehicle in park, have someone rev the engine while you observe the mounts. Excessive movement in a specific area can indicate a failing mount.
- Listen for Noises: Pay attention to where clunking or banging noises are coming from. This can help pinpoint the problematic mount.
- Professional Diagnosis: If you’re unable to identify the issue yourself, a professional mechanic can use specialized tools to test the motor mounts and determine which one is bad.
What to Do If You Have a Bad Motor Mount
If you suspect a bad motor mount, it’s important to address the issue promptly to avoid further damage to your vehicle. Here’s what you can do:

Frequently Asked Questions
Do I need to replace all four motor mounts?
Therefore, you may need to take action soon because when one engine mount is damaged, more pressure is placed on all other mounts, which can accelerate the wear of these too. So, you may have to change more than one mount, if not all, engine mounts depending on how much damage has been caused.
How many hours does it take to replace motor mounts?
In some cases, a professional mechanic might be able to replace some mounts in about one hour, while in many other instances, a mount replacement can take several hours and even an entire workday.
Can you drive with 1 bad motor mount?
A failing motor mount can lead to serious engine damage and will also greatly impact the performance of the vehicle. It is very unsafe to drive with a broken motor mount. If you feel a lot of vibration in the vehicle while you are driving, there's a good chance it's the motor mount.
Should you replace all motor mounts at the same time?
In summary, while it's not strictly necessary to replace all motor mounts at once, doing so can provide better performance and longevity for the vehicle, especially if multiple mounts show signs of wear.
Is replacing engine mounts a big job?
For some vehicles and motor mounts, you may need to remove parts of the subframe or other engine bay parts to access the mounts, but if you take the time and have the correct tools, replacing your motor mounts is usually a Saturday job.
How do I tell which motor mount is bad?
The classic ``backyard mechanic'' way to check a motor mount was/is to lift the hood, start it up, put it in gear, keep your left foot on the brake and give it some gas with your right foot. If the engine lifts, the mount is bad. Alternating between Drive and Reverse will test the mounts on both sides.

Passenger mount fails first in my opinion. Most of the weight of the engine is shifted towards this side. Transmission mount at the firewall is the second one that fails.
Do you have to lift the engine to replace motor mounts?
Sometimes a long extension and universal joint is the way to go. Step 4: Next, crawl under the vehicle and loosen the mount-to-frame bolts. Step 5: Jack-up the engine a little at a time and remove the motor mount.
