Nissan Maxima Engine Mount Guide: 2005-2009 Models
Experiencing vibrations or clunking noises in your Maxima? Your engine mounts may be the cause.
- Your Maxima likely has electronic, fluid-filled mounts; replacing them with cheap, solid rubber aftermarket mounts will cause vibration.
- Symptoms include heavy vibration at idle, and clunking noises when shifting or accelerating.
- The rear engine mount is very difficult to replace and may require lowering the subframe.
- For best results, choose premium aftermarket brands that replicate the OEM design or use genuine OEM parts to avoid vibration issues.
Is Your Maxima Shaking? Signs of a Failing Engine Mount
A worn-out engine mount on a 2005-2009 Maxima will make its presence known. The powerful V6 engine creates a lot of torque, and if the mounts are weak, you'll feel and hear it. Look for these common symptoms:
- Excessive Vibration: This is the most common sign. You might feel a strong vibration through the steering wheel, floor, or seats, especially when the car is idling in gear (like at a stoplight).
- Clunking or Thumping Noises: Loud clunks, bangs, or thuds when you accelerate, decelerate, or shift between Drive and Reverse are classic signs of a bad mount. This is the sound of the engine shifting and hitting its limits.
- Visible Engine Movement: If you have a helper, you can check for this. With the hood open and the parking brake set firmly, have them shift the car from Park to Drive or Reverse while holding the brake. If you see the engine lurch or jump more than an inch or two, a mount has likely failed.
OEM vs. Aftermarket: The Vibration Warning
Your 2005-2009 Maxima likely came with at least two electronically controlled, fluid-filled engine mounts. These "active" mounts are crucial for the car's smooth, quiet ride. Many budget aftermarket mounts are just solid blocks of rubber. While they fit, they cannot dampen vibrations as effectively and often lead to a noticeable increase in cabin vibration, a common complaint among owners who choose cheaper parts.
Choosing the Right Aftermarket Mount for Your Maxima
When shopping for aftermarket mounts, it's helpful to think in tiers. Not all aftermarket parts are created equal, and the price often reflects the quality and technology inside the mount.
Tier 1: Premium Aftermarket (Closer to OEM)
Brands like Beck Arnley fall into this category. They are known for trying to match OEM specifications and quality. For a sensitive system like the Maxima's, choosing a premium aftermarket brand that specifically offers a hydraulic or electronic replacement is your best bet to avoid vibration issues. They cost more than budget options but are typically less expensive than going to the dealer.
Tier 2: Budget Aftermarket
Brands like Anchor, DEA, and Westar are widely available and affordable. These are often solid rubber mounts that lack the advanced damping of the originals. While they will secure your engine, be prepared for a potential increase in vibration at idle. These can be a reasonable choice if budget is your primary concern and you can tolerate a less-smooth ride, or for the mounts on your car that are not electronic. Forum users report these mounts may not last as long as OEM or premium options.
Pro Tip: Before ordering, visually inspect your existing front and rear engine mounts. Look for any wires or electrical connectors attached to them. This is the surest way to confirm you have electronic mounts and need to order the correct type of replacement.

Frequently Asked Questions
Are there any recalls for the 2005-2009 Maxima engine mounts?
No, there are no recalls or common Technical Service Bulletins (TSBs) from Nissan or the NHTSA specifically for the engine mounts on this generation of Maxima.
Why are my new aftermarket mounts vibrating so much?
This is a common issue. It usually happens when a fluid-filled or electronic OEM mount is replaced with a cheaper, solid rubber aftermarket mount. The solid rubber is stiffer and transmits more of the engine's natural vibrations into the car's frame, which you feel in the cabin.
How many engine mounts does the 2005-2009 Maxima have?
This vehicle uses a set of four mounts to secure the engine and transmission. This typically includes a front mount, a rear mount, a right-side (passenger side) engine mount, and a transmission mount.
Can I just replace the one broken mount?
While you can, it's often not the best long-term solution. Engine mounts wear together. A single new, stiff mount surrounded by old, soft ones can put extra stress on the other mounts, causing them to fail sooner. If one has failed, the others are likely worn and nearing the end of their service life.
How difficult is it to replace the mounts myself?
This is a moderately difficult job for a DIY mechanic. While the front and side mounts are relatively accessible, the rear mount is known to be very difficult. It often requires supporting the engine and lowering the subframe to gain access, which can be challenging without a vehicle lift.
