A Practical Guide to Replacing Engine Mounts on Your 2010-2020 Nissan Frontier
Feeling a new vibration in your Frontier? It might be time for new engine mounts.
- The most common sign of failure is a new, excessive vibration at idle that is different from the engine's normal character.
- Before replacing mounts for a vibration issue, be aware of TSB NTB13-021b, which addresses idle vibration through other means.
- Replacement is a feasible DIY job that requires safely supporting the engine.
- For best results and to avoid vibration issues, choosing a premium aftermarket brand like Beck Arnley or OEM parts is recommended over standard value brands.
Is Your Frontier Shaking? Signs of a Bad Engine Mount
When an engine mount wears out, the rubber cracks or separates. This allows the engine's vibration to transfer into the truck's frame. You will feel this in the cabin. It's important to distinguish this from the normal idle characteristics of the 4.0L V6 engine, which some owners find naturally rough. A bad mount will cause a new or worsening vibration.
- Excessive Vibration: This is the most common sign. You'll feel a strong vibration through the steering wheel, floor, or seats, especially when the truck is idling at a stop light.
- Clunking Noises: You might hear a 'clunk' or 'thud' from the engine bay when you accelerate, brake, or shift from Drive to Reverse. This is the sound of the engine moving too much and hitting other parts.
- Visible Engine Movement: Have a friend help you. With the parking brake on, have them shift the truck between Drive and Reverse while you watch the engine. If the engine rocks back and forth more than an inch or two, the mounts are likely worn out.
Known Issues & TSBs
Nissan has issued Technical Service Bulletins (TSBs) for issues that can feel like bad engine mounts. TSB NTB13-021b addresses a rough idle vibration and suggests an ECU update, not a mount replacement, unless the mount is visibly leaking fluid. TSB NTB14-060c notes that a single 'thunk' noise during the first few accelerations of the day can be normal for these mounts and is not a reason for replacement on its own.
Choosing the Right Aftermarket Engine Mount
When shopping for new engine mounts, you have a choice between OEM (Original Equipment Manufacturer) and aftermarket parts. For a part that controls vibration, quality matters. A cheap, poorly made mount can cause more vibration than the old one you're replacing.
Here’s a breakdown of the brands available:
- Premium Aftermarket (Beck Arnley): Beck Arnley focuses on making parts that match the original OE quality in fit and function. They are often considered the best choice after the dealer part and are a solid option for a smooth, long-lasting repair.
- Standard / Value (Anchor, Westar, DEA, Pioneer Cable): These brands offer a more affordable solution. They are a practical choice for budget-conscious repairs. While they meet basic specifications, the rubber quality and vibration damping may not be on par with premium or OEM options, potentially leading to a shorter lifespan or slightly more noticeable vibration.
Pro Tip: Many experienced owners and mechanics recommend using either OEM or a premium aftermarket brand like Beck Arnley for engine mounts. The extra cost is often worth it to ensure a smooth ride and avoid having to do the job twice.

Frequently Asked Questions
Is replacing engine mounts a DIY job?
Yes, for someone with moderate mechanical skill and the right tools. You will need to safely support the engine from below with a floor jack and a block of wood. The job requires metric sockets, long extensions, and a torque wrench. Several video guides are available online that show the process specifically for the Frontier.
How many engine mounts does my Frontier have?
The 2010-2020 Nissan Frontier has two main engine mounts (left and right) and one transmission mount at the rear of the transmission, which also helps control drivetrain movement. It's often a good idea to inspect the transmission mount when replacing the engine mounts.
Will new engine mounts fix my Frontier's rough idle?
It depends. If the mounts are truly collapsed and broken, replacement will significantly reduce vibrations. However, the 4.0L V6 engine in this generation is known for having a certain amount of idle vibration even when new. If your mounts look okay, the vibration might be related to the engine's tuning, as noted in Nissan's TSB NTB13-021b.
Should I replace both engine mounts at the same time?
Yes, it is highly recommended. Engine mounts wear out from age and mileage, so if one has failed, the other is likely not far behind. Replacing them in pairs ensures even support for the engine and prevents the new mount from being stressed by an old, failing one on the other side.
