INFINITI JX35 (2013) Engine Torque Strut Mount: A Comprehensive Guide
Experiencing vibrations or clunking noises in your JX35? Your engine torque strut mount might be the culprit.
- A single 'thunk' noise on initial acceleration may be normal per TSB ITB14-053b, but persistent clunking and vibration are signs of failure.
- The torque strut mount is the easiest to replace; other mounts require supporting the engine and are more complex.
- Aftermarket brands like Beck Arnley, Anchor, and Westar are reliable, cost-effective alternatives to OEM parts.
- Ignoring a bad mount can lead to damage to other components like axles, hoses, and the transmission.
Is Your JX35's Engine Mount Failing?
A worn-out engine torque strut mount is a common issue that can cause noticeable problems. Because this part is made of rubber and is constantly under stress, it will degrade over time from heat and movement. If you're feeling new vibrations or hearing strange noises, it's a good idea to check your engine mounts.
Symptoms of a Bad Torque Strut Mount
- Excessive Vibration: This is the most common sign. You might feel a strong vibration through the steering wheel, seats, or floor, especially when idling at a stoplight with the car in 'Drive'. This happens because the mount can no longer absorb the engine's natural vibrations.
- Clunking or Thumping Noises: A loud 'clunk' or 'thump' from the engine bay when you accelerate, shift from Park to Drive, or brake can indicate a failed mount. This sound is the engine itself moving and hitting other parts because the mount isn't holding it securely.
- Visible Engine Movement: In severe cases, you might see the engine lurch or rock in the engine bay when revving the engine or shifting gears. An engine should not move more than an inch or two.
Important TSB Note: A "Normal" Clunk
Infiniti issued a Technical Service Bulletin (TSB ITB14-053b) stating that a "single thunk noise" from the front engine mount during the first few accelerations of the day is a normal characteristic. Do not replace the mount for this specific noise, as it does not indicate a failure. However, persistent clunking during regular driving is a sign of a problem.
Choosing the Right Aftermarket Mount
When replacing the torque strut mount, you have options outside of the expensive OEM part. Aftermarket parts can offer the same quality for less money. However, quality can vary, so it's important to choose wisely. For a luxury vehicle like the JX35, using a very cheap, solid rubber mount can sometimes lead to more vibrations than the worn-out original part.
Aftermarket Brand Tiers
- OEM Equivalent Quality (Beck Arnley): Beck Arnley has a reputation for often providing parts that match factory dimensions and quality, and sometimes even repackages the original OEM part without the dealer markup. This is a strong choice for owners who want as close to factory feel as possible without the factory price.
- Trusted Aftermarket (Anchor, Westar): Brands like Anchor and Westar are well-known in the aftermarket industry and trusted by many mechanics. They engineer their mounts to meet OE standards and use quality rubber to ensure performance and longevity. These brands offer a great balance of price and reliability.
- Budget-Friendly (DEA): DEA is a long-standing aftermarket brand known for affordable parts. While they can be a practical choice, some user forums report mixed experiences with longevity and potential for increased vibration compared to OEM or higher-tier aftermarket brands.
Pro Tip: Check All Mounts
Your JX35 has multiple engine and transmission mounts. When one fails, it puts extra stress on the others, causing them to wear out faster. If you are replacing one failed mount, it's a good practice to inspect the others for cracks, leaks (if hydraulic), or excessive wear.
Cost of Replacement
The cost to replace an engine torque strut mount can vary. The part itself is relatively inexpensive, but labor can add up if you have a shop do the work. The torque strut mount is often the most accessible of the engine mounts, making it a feasible DIY project for those with the right tools.
| Item | Estimated Cost |
|---|---|
| New Aftermarket Part | $40 - $88 |
| New OEM Part | $170 - $280 |
| Shop Labor | $100 - $200 |
| Total Professional Replacement (Aftermarket) | $140 - $288 |
| Total Professional Replacement (OEM) | $270 - $480 |
Note: Prices are estimates and can vary based on location and specific repair shop rates. The total cost for a full set of engine mounts can be significantly higher.
Frequently Asked Questions
Can I drive with a bad engine torque strut mount?
While you can drive for a short time, it's not recommended. A failed mount puts extra stress on other components like the transmission, CV axles, and other engine mounts. The excessive engine movement can eventually cause damage to hoses, wiring, or the exhaust system, leading to more expensive repairs.
Is this a difficult DIY repair?
For the torque strut mount (often called a 'dog bone' mount), it is generally one of the easier engine mounts to replace. It's typically located at the top of the engine and is easily accessible. A DIY-er with a good socket set and basic mechanical knowledge can often complete the job in under an hour. 🎬 See this step-by-step torque strut mount replacement walkthrough. However, other engine mounts that support the engine's weight are much more difficult and require supporting the engine safely.
Are there any recalls on the 2013 JX35 engine mounts?
No, there are no safety recalls for the engine mounts on the 2013 INFINITI JX35. There were recalls for other issues like airbags, the hood latch, and brake software, but none related to the engine mounts themselves.
My car vibrates, but it's not the mount. What else could it be?
Vibration in the JX35 can also be caused by other issues. A TSB (ITB12-072C) points to a problem with the all-wheel-drive system's electric controlled coupling causing vibration from the rear during turns. Another TSB addresses a 'judder' or vibration from the CVT transmission itself. If replacing the mount doesn't solve the vibration, these other areas should be investigated by a qualified technician.
