A Guide to Replacing Engine Mounts on a 2005-2009 Nissan Frontier
Experiencing rough vibrations or clunking noises? Your Frontier's engine mounts might be the culprit.
- Symptoms of failure include heavy vibration, clunking noises, and visible engine movement.
- OEM mounts are fluid-filled (hydraulic) for a smoother ride; many cheaper aftermarket options are solid rubber and may increase vibration.
- Replacing both engine mounts at the same time is recommended for best results.
- The job is possible for a DIY mechanic with the right tools, but access to bolts can be challenging.
Symptoms of a Failing Engine Mount
When an engine mount on your Frontier goes bad, it can cause several noticeable problems. Because the mount is no longer holding the engine securely, you might feel excessive vibrations or hear strange noises.
- Excessive Vibration: This is the most common sign. You might feel a strong vibration through the steering wheel, floor, or seats, especially when the truck is idling or when you first accelerate.
- Clunking or Banging Noises: Loud clunks, bangs, or thuds from the engine bay are a serious symptom. This sound is often caused by the engine moving and hitting other parts when you accelerate, decelerate, or shift gears.
- Visible Engine Movement: If you open the hood and have a helper shift the transmission from Drive to Reverse (with the brake pedal firmly pressed), you might see the engine rock or lift excessively. A little movement is normal, but more than an inch or two suggests a bad mount. 🎬 Watch this guide to identify and locate failing engine mounts.
- Visible Damage: A visual inspection may reveal cracks in the rubber part of the mount or, in the case of hydraulic mounts, signs of fluid leakage. The rubber can become hard and brittle over time.
Choosing the Right Aftermarket Engine Mount
When replacing your Frontier's engine mounts, you have a choice between original equipment manufacturer (OEM) parts and aftermarket parts. While OEM mounts are a direct replacement, quality aftermarket options can offer good performance at a lower price. The key difference often comes down to the type of mount: hydraulic vs. solid rubber.
Hydraulic vs. Solid Rubber Mounts
Original mounts are hydraulic (fluid-filled) for a smoother, quieter ride. Many aftermarket options are solid rubber. Solid mounts are often more durable and less expensive, but they may transmit more engine vibration into the cabin, making the ride feel rougher. If you want to maintain the original ride quality, look for aftermarket brands that offer a hydraulic, OE-style replacement.
Aftermarket Brand Tiers
The brands available for your Frontier fall into different quality and price tiers.
- Beck Arnley: Often considered a higher-tier aftermarket brand, Beck Arnley is known for sourcing parts that match OEM specifications, particularly for Japanese vehicles like Nissan. They can be a good choice if you're looking for quality close to original without the full OEM price.
- Anchor, Westar, DEA: These brands are popular, budget-friendly options. They often produce solid rubber mounts which can be a durable, cost-effective fix, but may increase cabin vibration compared to the original hydraulic mounts. Forum discussions show mixed experiences, with some users satisfied for daily driving and others noting premature wear or a harsher ride.
- Pioneer Cable: This brand also offers replacements, falling within the general aftermarket category.
A Note on Premature Failure
Some Frontier owners have reported needing to replace engine mounts more frequently than on other vehicles, sometimes after only a few years. Using lower-quality aftermarket parts or having other issues like fluid leaks that drip onto the mounts can cause them to fail sooner. For longevity, many owners and mechanics recommend sticking with OEM or high-quality hydraulic aftermarket mounts.

Frequently Asked Questions
Is there a recall on the 2005-2009 Frontier engine mounts?
No, there are no specific recalls issued by Nissan or the NHTSA for the engine mounts on the 2005-2009 Nissan Frontier. However, there is a Technical Service Bulletin (TSB) that notes a "single thunk noise" during initial acceleration can be a normal characteristic of the two-piece mount design and does not warrant replacement unless other symptoms are present.
Can I replace the engine mounts myself?
Yes, this is a DIY-feasible job for someone with moderate mechanical skill and the right tools. You will need a good socket set with long extensions, a swivel adapter, a floor jack, and a block of wood to support the engine. The process involves supporting the engine, unbolting the old mounts from the frame and engine bracket, and installing the new ones. Access to some bolts can be tight.

When one engine mount fails, it's highly recommended to replace both at the same time, as the other is likely the same age and has been under extra stress.
Will a bad engine mount cause a check engine light?
While a bad engine mount itself doesn't have a sensor, the excessive vibration it causes can sometimes trigger the knock sensor. This can lead to a false knock sensor code or misfire code, which will turn on the check engine light.
