Stop the shaking and noise in your Vibe by choosing the right new aftermarket engine mounts.
- Vibration at idle is the most common symptom of a failing engine mount in a Vibe.
- The Pontiac Vibe shares its mount design with the Toyota Matrix, making parts widely available.
- For a DIY replacement, you must safely support the engine with a jack and a block of wood.
- Replacing mounts in pairs or as a full set is recommended for the best results and longevity.
Is Your Vibe Shaking? Signs of a Bad Engine Mount
As your 2003-2010 Pontiac Vibe ages, the rubber in the engine mounts can wear out, crack, or become saturated with oil. When this happens, they can no longer do their job effectively. You'll likely notice one or more of these symptoms:
- Excessive Vibration: The most common sign is a noticeable increase in vibration felt in the steering wheel, floor, or seats, especially when the car is idling in gear at a stop.
- Clunking or Banging Noises: You might hear a 'clunk' when you accelerate, shift gears, or brake. This is the sound of the engine moving and hitting other components because the mount is no longer holding it securely.
- Visible Engine Movement: If you have a helper, you can observe the engine while they shift the car from Park to Reverse or Drive with the brake pedal held down. If the engine lifts or jerks excessively (more than an inch or so 🎬 Watch a video on how to diagnose bad engine mounts.), one or more mounts are likely bad.
- A Rougher Ride: Worn mounts can't absorb road shocks and engine vibrations properly, leading to a generally bumpier and less comfortable ride.
Don't Ignore the Signs
While a bad engine mount won't stop your car from driving, ignoring it can lead to bigger problems. Continued engine movement can stress and damage other parts like exhaust pipes, hoses, and wiring.
OEM vs. Aftermarket Mounts for Your Vibe
Since the Pontiac Vibe is a mechanical twin of the Toyota Matrix, its original equipment (OEM) parts are made to Toyota's high-quality standards. However, for an older vehicle, high-quality aftermarket mounts offer a great balance of performance and value. Some owners have noted that cheaper aftermarket mounts can cause more vibration, especially in cold weather, due to harder rubber compounds. It's often recommended to replace mounts in sets (e.g., front and rear together) to ensure the engine is evenly supported.

When shopping for new aftermarket mounts, you'll find several brands available. Here's a general breakdown:
- Premium Aftermarket (e.g., Beck Arnley): These brands often focus on matching OEM specifications for fit and material quality. They are a solid choice if you want performance close to the original without the dealer price tag.
- Standard Aftermarket (e.g., Anchor, Westar, DEA): These are popular, budget-friendly options. They are widely used and generally considered a practical choice for daily drivers. While some users report good experiences, others have noted a shorter lifespan or increased vibration compared to OEM. For an aging Vibe, they represent a cost-effective repair.
Pro Tip: Replace in Pairs
When one mount fails, the others are often not far behind. Replacing the front and rear mounts together, or all four at once, can save you time and ensure the new mounts aren't put under extra stress by old, worn-out ones.

The cost to replace your Vibe's engine mounts will vary based on which mounts you replace and whether you do the work yourself.

|---|---|
| New Aftermarket Mount (Single) | $35 - $128 |
| New OEM Mount (Single) | $175 - $300+ |

Frequently Asked Questions
How many engine mounts does my 2003-2010 Vibe have?
Most Pontiac Vibes have four mounts in total. There is a passenger-side mount (often called a torque strut), a transmission mount on the driver's side, a front mount, and a rear mount. The 2.4L AWD models also have four mounts.
Can I replace just one bad engine mount?
Yes, but it's often not the best strategy. A new, stiff mount paired with old, soft ones can put extra stress on the remaining mounts and may not fully resolve vibration issues. It is often recommended to replace the front and rear mounts as a pair.
Are Pontiac Vibe and Toyota Matrix engine mounts the same?
Yes, for corresponding years and engine sizes, the engine mounts are generally interchangeable between the Pontiac Vibe and Toyota Matrix. Always verify the part number and fitment for your specific vehicle configuration (engine, transmission, and drivetrain).
Is replacing engine mounts a DIY job?
For a home mechanic with the right tools, yes. The front and passenger-side mounts are relatively easy to access. The rear mount is known to be difficult due to tight spaces. The job requires a floor jack and a block of wood to safely support the engine's weight 🎬 Follow this step-by-step guide to replace your motor mounts. while you unbolt the old mount and install the new one.
