A Mechanic's Guide to the 2008-2015 Volvo XC90 Engine Torque Strut Mount
If you're feeling vibrations or hearing clunks from your engine, your upper torque strut mount is the likely cause.
- The upper engine torque strut mount is a common failure item on 2008-2015 XC90s, causing vibrations and clunking noises.
- Replacement is very easy and can be done in under 30 minutes with basic tools, making it a great DIY task.
- Owners of 2008 V8 models must check for NHTSA recall 08V206000 regarding engine mount bolts.
- For best results and a smoother ride, Genuine Volvo or OEM-supplier parts are recommended over economy brands like Anchor or DEA.
Symptoms of a Failing Torque Strut Mount
When the rubber bushings in the torque strut mount wear out, crack, or collapse from age and heat, you'll start to notice. The signs are often subtle at first but become more obvious over time. Most owners report issues starting between 60,000 and 100,000 miles.
- Vibrations at Idle: A common first sign is a new or increased vibration felt in the steering wheel or through the cabin while the car is in drive but stopped.
- Clunking or Thumping Noises: You may hear a distinct "clunk" or "thump" from the engine bay when you accelerate, brake, or shift from Park into Drive or Reverse. This is the sound of the engine moving more than it should.
- Scraping or Grinding Sounds: Some owners describe a scraping or grinding noise when accelerating from a stop as the engine shifts and makes contact with other parts.
- Visible Wear: You can often see the failure. Pop the hood and look at the mount located at the top of the engine. If you see that the rubber bushing is cracked, torn, or has a large gap around it, it needs to be replaced. 🎬 Watch how to identify and swap a worn upper engine mount.
Recall Notice for 2008 V8 Models
A small number of 2008 Volvo XC90s with the V8 engine were recalled for incorrect engine mount bolts (NHTSA Campaign ID 08V206000). These bolts were too long and didn't provide enough clamping force, which could cause the mount bracket to break and the engine to stall. It is critical to verify with a dealer or on the NHTSA website that this recall has been performed on your vehicle.
Choosing the Right Aftermarket Mount
When replacing your torque strut mount, you have a choice between Genuine Volvo parts and various aftermarket brands. For a component that so directly affects ride quality, the choice matters.
Genuine Volvo / OEM Supplier (e.g., Hutchinson): The original part provides the best vibration damping and longevity. Volvo has updated this part over the years to improve durability. Choosing a Genuine part or one from an Original Equipment Manufacturer (OEM) like Hutchinson ensures you get the correct rubber density for a smooth ride. This is the recommended choice for owners who want to restore the car's original feel.
Economy Aftermarket Brands (e.g., Anchor, DEA): Brands like Anchor and DEA are widely available and affordable. They are functional replacements that will fit your XC90. However, many experienced Volvo owners and mechanics report that these mounts use a harder rubber compound. This can result in more noticeable cabin vibration compared to the original part. While they work as a budget-friendly fix, they may not last as long or provide the same level of refinement.
A Note from the Mechanic
The upper torque strut is one of the easiest engine mounts to replace on the XC90. However, if this mount has failed, it has likely put extra stress on the other, harder-to-reach engine mounts. While you're replacing the upper mount, it's a good idea to inspect the other mounts for signs of wear, especially the lower torque mount and the main hydraulic engine mounts.

Frequently Asked Questions
Is the engine torque strut mount the same for all 2008-2015 XC90 engines?
The upper torque strut mount is generally the same for the 3.2L I6 engine across these years. However, the V8 and diesel models (not common in the US) may use different parts. Always verify the part number fits your specific year and engine before ordering.
Can I drive with a bad torque strut mount?
Yes, but it's not recommended for long. A failed mount allows excessive engine movement, which puts stress on other engine mounts, transmission mounts, exhaust pipes, and various hoses. Addressing it sooner rather than later prevents more expensive repairs down the road.
How difficult is it to replace the torque strut mount myself?
This is a very DIY-friendly job. It is located at the top of the engine and is easily accessible. The replacement typically involves removing a few bolts, swapping the old mount for the new one, and tightening the new bolts. The entire process can often be done in under 30 minutes with basic hand tools.
