INFINITI QX60 (2014-2020) Engine Torque Strut Mount Replacement Guide
If your QX60 is vibrating or making a clunking noise, the engine torque strut mount could be the cause.
- A 'single thunk' noise on the first few accelerations is normal per TSB ITB14-053b and not a sign of failure.
- The most common failure symptoms are excessive vibration at idle and a clunking noise when shifting gears.
- Budget aftermarket brands (Anchor, DEA, Westar) are affordable but may not last as long or ride as smoothly as OEM or premium aftermarket parts.
- Replacing the upper torque strut mount is a feasible DIY job for most owners and can be done in about an hour.
Is Your QX60's Ride Not as Smooth as It Used to Be?
A common issue as the INFINITI QX60 ages is the failure of its engine mounts. The engine torque strut mount, often called a torque rod or dog bone mount, is frequently the first to wear out. It is located at the top of the engine and is responsible for controlling engine movement. When it fails, you'll feel it. This guide will help you understand the symptoms, choose the right aftermarket part, and know what to expect during replacement.
Symptoms of a Failing Torque Strut Mount
A bad torque strut mount makes its presence known in a few distinct ways. A QX60 owner on a forum described their vehicle shaking while idling and accelerating, which was diagnosed as a motor mount issue. Common symptoms include:
🎬 Watch this video to see and hear common motor mount symptoms.- Vibration at Idle: The most common sign is a noticeable vibration felt in the steering wheel, seats, or floor, especially when the transmission is in 'Drive' at a stoplight.
- Clunking or Thumping Noises: You might hear a 'clunk' or 'bang' when you shift into Drive or Reverse, or when you accelerate hard. This is the sound of the engine shifting and hitting its limits because the mount can no longer hold it steady.
- Jerking or Lurching: The vehicle may feel like it jerks when accelerating or shifting, as the loose engine disrupts the drivetrain's smoothness.
Important TSB Note: Is That 'Thunk' Normal?
Infiniti issued a Technical Service Bulletin (TSB ITB14-053b) for the QX60. It states that a 'single thunk noise' from the front of the engine during the first few accelerations of the day is a normal characteristic. Do not replace the mount for this specific sound, as it is not considered a failure.
Choosing the Right Aftermarket Mount: Brand Tiers
When replacing the torque strut mount, you don't have to buy the expensive OEM part. Aftermarket options can provide good value, but quality varies. Aftermarket mounts are generally seen as more affordable but potentially less durable than OEM parts.
- Value Tier (Anchor, DEA, Westar): These brands are the most affordable. They are a practical choice for budget-conscious repairs. However, online forums show mixed reviews; some users report they work fine for years, while others have experienced premature failure in as little as a few months. These are a trade-off: you save money, but the part may not last as long as a premium option.
- Standard Tier (Pioneer Cable): Brands like Pioneer are often considered a step up. They may use materials and construction closer to the original factory part. For a daily-driven luxury vehicle like the QX60, spending a little more for a standard-tier part can provide better longevity and vibration damping.
- OEM (Original Equipment Manufacturer): This is the part you would get from an Infiniti dealer. It offers a guaranteed fit and original quality but comes at the highest price.
Pro-Tip: A Word on Rubber Hardness
Aftermarket mounts, especially budget brands, may use a harder rubber compound than the original part. This can make them durable, but it might also transmit slightly more vibration into the cabin, which can be noticeable in a luxury vehicle like the QX60. This is a common trade-off between cost and ride comfort.

Frequently Asked Questions (FAQ)
Can I replace just the one bad torque strut mount?
Yes, you can replace only the failed mount. The torque strut is often the first to go. However, if one mount has failed from age, the others may be weakened. A failed mount puts extra stress on the others, so inspect the remaining mounts for cracks or excessive movement.
🎬 See how to locate and inspect your mounts for damage.Is there a recall for the QX60 engine mounts?
No, there are no safety recalls for the engine mounts on the 2014-2020 INFINITI QX60. The only official notice is TSB ITB14-053b, which clarifies that a specific 'thunk' noise is normal.
How difficult is it to replace this mount myself?
For the upper torque strut mount, the job is relatively easy for a DIYer with basic tools. It is typically held in by two or three bolts and is accessible from the top of the engine bay. Unlike the main weight-bearing mounts, you do not need to support the engine to replace this specific part. The job can usually be done in under an hour.
