Engine Torque Strut Mount Guide for the 1988-1997 Oldsmobile Cutlass Supreme
Stop the clunking noises and engine vibrations in your Cutlass Supreme by understanding and replacing the torque strut mount.
- A clunking noise when shifting or accelerating is the most common sign of a bad torque strut mount.
- This is a simple, low-cost DIY repair that can be done in under 30 minutes with basic tools.
- Standard aftermarket brands like Westar or Pioneer offer a good balance of quality and value for this repair.
- While you can drive with a bad mount, it's best to replace it soon to prevent damage to hoses, axles, and the exhaust system.
Signs of a Failing Torque Strut Mount
When the torque strut mount on your Cutlass Supreme wears out, the rubber cracks or separates, and it can no longer control the engine's movement. This failure puts extra stress on the other engine mounts, transmission, and even exhaust components. Watch for these common symptoms:
- Clunking or Thudding Noises: A loud 'clunk' when you accelerate, brake, or shift from Park into Drive or Reverse is a classic sign. This is the sound of the engine lurching and hitting its limits because the mount is no longer holding it steady.
- Excessive Vibration: You may feel a new, strong vibration in the steering wheel, floor, or seats, especially when the car is idling in gear. This happens because the worn-out rubber can no longer absorb the engine's vibrations. 🎬 Watch this video to see common signs of mount failure.
- Visible Engine Movement: With the hood open, the parking brake set, and the car in Park, have a helper briefly rev the engine. If you see the engine rock or jump excessively, the mount has likely failed. 🎬 Learn how to locate a bad mount in eight minutes.
Don't Ignore a Bad Mount
Continuing to drive with a completely failed torque strut mount can cause more expensive problems. The uncontrolled engine movement can damage radiator hoses, wiring, exhaust pipes, and CV axles. It's best to replace it soon to avoid further damage.

Since original GM parts for this generation of Cutlass Supreme are often discontinued, the aftermarket is your primary source. The quality can vary, so it's important to know the differences between brands.
For a daily driver, most owners find that standard aftermarket brands provide a good balance of price and performance. Brands are generally available in the following tiers:
- Economy (Anchor, DEA): These are typically the most affordable options. Forum discussions show mixed reviews; some users report success, while others experience premature failure or fitment issues. They can be a viable option for a budget-conscious repair, but be aware that the rubber may be harder, leading to slightly more vibration, or softer, leading to a shorter lifespan.
- Standard Replacement (Westar, Pioneer): Often seen as a step up from economy brands, Westar and Pioneer are trusted by many mechanics for daily-driven vehicles. They aim to meet or exceed original specifications and often receive positive feedback for fit and function. These brands represent a solid middle-ground for quality and durability.
Pro Tip: The torque strut mount is often called a "dog bone" mount. Your Cutlass Supreme has several other mounts, including two main engine mounts and a transmission mount. If the top torque strut has failed, the other mounts have been under extra stress. It's a good practice to inspect all of them and consider replacing them as a set to ensure a long-lasting repair.

Frequently Asked Questions (FAQ)
Is this the same as a motor mount?
A torque strut mount is a specific type of engine mount. Its main job is to control the twisting or rocking motion of the engine, while the primary motor mounts support the engine's weight. Your car uses both to keep the powertrain secure.
How difficult is it to replace this mount myself?
This is a very DIY-friendly job. The torque strut mount is usually located at the top of the engine and is held in by just two or three bolts. Basic hand tools like a socket set and wrenches are all that's typically needed. The job can often be completed in under 30 minutes.
Are there any recalls for the engine mounts on my Cutlass Supreme?
There are no specific recalls for the engine torque strut mount itself. However, a significant recall (NHTSA #97V058 and #00V189000) was issued for 1988-1991 models concerning front subframe/engine cradle bolts that could corrode and fail, potentially allowing the steering to separate. While not a mount failure, it's a critical safety issue for the affected years. It is recommended to ensure this recall repair was performed.
Should I use a mount with polyurethane bushings?
For a street-driven car, it is best to stick with the standard rubber bushings. Aftermarket polyurethane (poly) bushings are available for performance applications, but they are very stiff. While they control engine movement extremely well, they also transmit much more engine vibration into the cabin, which can be harsh and noisy for a daily driver.

Technical Specifications
The engine torque strut mount, also known as a 'dog bone' mount, is typically made of a central rubber bushing bonded between two metal mounting points. For the 1988-1997 Cutlass Supreme, these are solid rubber mounts, not hydraulic (fluid-filled). The replacement is a direct-fit part with no modification required.
