Summary
  • Also called an engine mount, the torque strut mount keeps the engine’s position stable in relation to the chassis.
  • Torque strut mounts weaken over time, but improper installation can accelerate wear.
  • The symptoms of a bad torque strut mount include clunking sounds, excessive vibrations, and wear that you can see with your eyes.
  • It’s unsafe to drive with a bad torque strut mount.
  • An engine mount replacement job can go anywhere between $150 and $900, including labor costs.

Your vehicle has many parts that are all important to its operation. These include engine mounts that help ensure that the engine doesn’t shake or move inside the chassis and prevent engine vibrations from being felt by the driver and passengers.

In this article, we’ll talk about torque strut mounts, what they are, and how to know if they’re faulty.

What Is a Torque Strut Mount?

A torque strut mount stabilizes your engine’s position in relation to the chassis. It keeps everything steady while the engine is trying to torque over when the vehicle runs or stops. In short, it lessens the effect of engine torque on your ride’s stability.

Whenever a front wheel drive transverse engine vehicle accelerates, the engine and transaxle will try to roll backwards due to the twisting force applied by the drivetrain to the front wheels. Strut mounts are in place to prevent this. Mechanics sometimes call these “dog bones” because of the way some of them are shaped.

Not all engines have strut mounts. Some simply have the engine mounts configured to do the job of preventing drivetrain “roll” during acceleration. Some 90s GM V6 engines use two strut mounts.

What Causes Torque Strut Mounts to Fail?

It’s normal for torque strut mounts to weaken over time, as their rubber material can eventually crack. Once this happens, you’ll have to take your vehicle to an auto repair shop to have them replaced.

Aside from natural wear, incorrect installation can cause your strut mount to wear out faster than expected. To avoid the hassle of dealing with a faulty torque strut mount due to improper installation, let a licensed mechanic do the installation for you.

Bad Torque Strut Mount Symptoms

Don’t wait for issues to crop up before taking your daily driver to an auto repair shop. If you notice the symptoms below, don’t delay. These are telltale signs of bad torque strut mounts, but they could also point to other problems. A licensed mechanic can diagnose the issue in no time.

Excessive Vibrations

Excessive vibrations coming from the steering wheel or floorboard while you’re driving is a telltale sign of bad torque strut mounts. If left unresolved, they can damage the engine and cause other problems.

Clunking Sound

A bad torque strut mount can give out a clunking sound when your ride is accelerating. When one or more mounts are loose, your engine can come into contact with other components, causing a “clunk” or “impact noise.”

Visible Signs of Wear

Corrosion, cracks, or warps in the rubber part of your torque strut mounts can minimize its ability to dampen vibrations. These mounts are engineered to reduce vibrations, and any deformity can cause them to fail.

Is It Safe to Drive With a Bad Torque Strut Mount?

No, it’s not. While you can drive with a bad mount for a certain period, it’s highly recommended that you don’t.

The vibrations will become more noticeable over time and cause problems that can make driving risky. You’ll compromise your engine and other components if you continue driving.

How Long Do Engine Mounts Last?

Engine mounts can last around five to seven years before they wear out. But don’t wait that long to have your ride checked if you’re already noticing torque strut mount problems.

It’s a good idea to have your engine mounts checked whenever you go for an oil change or whenever you get your engine serviced. Catching any engine issue early is better than shelling out more money on complex repairs.

How Much Does a Torque Strut Mount Replacement Cost?

An engine mount replacement can go anywhere between $150 and $900, including labor costs.

Because there are many types of engine mounts, the location of the mount and your specific vehicle can affect the cost.

If you want to install your new torque strut mount on your own, you can get an aftermarket replacement for $20 to $25.

Choosing the Best Torque Strut Mount for Your Ride

Many torque strut mounts are available on the market, but that doesn’t mean all of them are compatible with your vehicle. Engine mounts come in different configurations and designs, depending on the ride’s year, make, and model. So, make sure to check if the strut mount you’re buying is compatible with your ride to avoid any issues in the future.
