Your Guide to the 1993-2005 Buick Century Engine Torque Strut Mount
Stop the clunking and shaking in your Buick Century by understanding and choosing the right engine torque strut mount.
- A clunking noise when shifting from Park to Reverse is the most common sign of a failed torque strut mount on your Century.
- Replacement is an easy and affordable DIY job that can be done in under an hour with basic tools.
- Aftermarket brands like Anchor, DEA, and Westar are a very budget-friendly fix, but may not last as long as the original ACDelco part.
- There are no recalls or TSBs for this part; failure is a common result of age and normal wear.
Symptoms of a Failing Torque Strut Mount
When the rubber in your Century's torque strut mount wears out, the signs are hard to miss. The rubber cracks and degrades from age and heat, losing its ability to absorb engine movement. You will likely notice one or more of the following symptoms:
- Clunking or Thudding Noises: A distinct 'clunk' from the engine bay when you shift from Park into Drive or Reverse is a classic sign. You may also hear it when you accelerate or decelerate.
- Excessive Vibration: You might feel a new, heavy vibration through the steering wheel or floor, especially when the car is stopped at a light with the transmission in Drive.
- Visible Engine Movement: If you have a helper, you can see the problem. With the parking brake on and the car in Drive, have them hold the brake pedal firmly and briefly tap the gas. If you see the engine lurch or rock more than an inch or so, the mount has failed. 🎬 Watch: Simple DIY checks to confirm your engine mount has failed.
Known Issues: Recalls and Service Bulletins
Searches of the National Highway Traffic Safety Administration (NHTSA) database and technical service bulletins (TSBs) show no specific recalls or bulletins for engine torque strut mount failure on the 1993-2005 Buick Century. This means that when this part fails, it is due to normal wear and tear over time, not a manufacturing defect.
Choosing the Right Aftermarket Mount
For a vehicle like the 1993-2005 Buick Century, you have a choice between original equipment (OEM) parts and several aftermarket brands. Here’s an honest breakdown to help you decide.
OEM-Tier (ACDelco)
ACDelco is the original parts brand for General Motors. Choosing an ACDelco mount will give you the same quality, fit, and ride smoothness as the part that was on your car when it was new. However, this quality comes at a significantly higher price, which many owners don't find necessary for an older vehicle.
Economy Aftermarket (Anchor, DEA, Westar, Pioneer)
These brands offer a very affordable way to fix the problem. For a simple part like a torque strut on a Century, they are a practical choice. However, it's important to have realistic expectations.
- Honest Assessment: Forum discussions and mechanic reviews show mixed results for these brands. Some owners use them for years without issue, while others report they wear out much faster than the original parts.
- The Trade-Off: You are trading longevity and potentially a slightly rougher feel for a much lower price. Given the low cost and ease of replacement, many owners feel this is a worthwhile trade-off.
Pro Tip: The 'Flip Trick' and What It Means
Some owners temporarily reduce clunking by removing the torque strut, rotating the inner rubber bushing 90 degrees, and reinstalling it. This works because the mount wears out in the direction of engine torque. While this is not a long-term fix, it confirms that the mount has failed and needs replacement.
Estimated Replacement Costs
The cost to replace a torque strut mount is very reasonable, especially if you do it yourself. The part itself is one of the most accessible mounts to change.
| Replacement Option | Estimated Cost |
|---|---|
| New Aftermarket Part (DIY) | $8.56 - $32.02 |
| Shop Labor Cost | $100 - $180 |
| Total Professional Replacement | $110 - $215 |
Frequently Asked Questions (FAQ)
Is it hard to replace a Buick Century torque strut mount myself?
No, this is considered an easy DIY job. The torque strut mounts are usually located at the top of the engine and are held in by just a few bolts (typically 15mm). You can often replace them one at a time without needing to support the engine with a jack. The entire job can usually be done in under an hour with basic hand tools.
🎬 Watch this video for a step-by-step Buick engine mount installation.Should I replace all the engine mounts at once?
It's a good idea, but not strictly necessary. All the mounts on your car are the same age. When one fails, it puts extra stress on the others, and they are likely weak as well. If you are paying for shop labor, replacing them all at once can save you money in the long run. If you are doing it yourself, you can simply replace the one failed torque strut to solve the immediate problem.
What's the difference between a torque strut and a motor mount?
A motor mount's primary job is to support the weight of the engine and absorb general vibration. A torque strut's primary job is to prevent the engine from twisting or rocking during acceleration and deceleration. Your Century uses a combination of both to keep the engine and transmission assembly secure.
🎬 See how to diagnose a bad motor or transmission mount.Will a bad torque strut mount cause my 'Check Engine' light to come on?
No, a failing torque strut mount is a mechanical part and will not trigger a 'Check Engine' light or any fault codes. The symptoms are purely physical, such as noise and vibration.

Technical Specifications
The engine torque strut mount, also known as a 'dog bone' mount, is a solid rubber and metal link that connects the top of the engine/transaxle assembly to the vehicle's upper radiator support or firewall area. It is designed to resist the rotational force (torque) of the engine. The system on a 1993-2005 Buick Century typically uses two of these upper torque struts.
