What is a Strut Mount? Symptoms, Replacement Cost, and More

When you do the maintenance for your vehicle, it’s important to know the parts of your car’s suspension system. One of them is strut mount. So what is a strut mount? Why is it important for your vehicle?
In this article, we will talk about strut mount, including its function, the common symptoms of failure, the cost of replacement, and more.

What Is A Strut Mount?

A strut mount is a crucial part that connects the suspension strut to the vehicle’s chassis. It acts as a cushion between the strut and the vehicle, which helps to absorb shocks and vibrations from the road. In addition, many front strut mounts have a bearing or bearing plate, which serves as the steering pivot, allowing for smooth and controlled steering.

Below is an introduction to its primary functions and features:

• Connection Point: The strut mount is a part that connects the strut assembly and the car body. It is the key point to maintain the integrity of the suspension system.
• Damping Vibrations: The rubber or urethane in the strut mount can help reduce the vibration and noise from the road, and make the ride more comfortable.
• Bearing Support: Some strut mounts are designed with a bearing or bearing plate, which allows the strut to rotate. This is very important for front-wheel-drive vehicles, as the strut is also a part of the steering system.
• Alignment: The strut mount can help keep the suspension system’s correct alignment. It makes the vehicle handle correctly and keeps the tire wear even.
• Load Bearing: The strut mount bears the weight of the vehicle and the forces during driving. It should be strong enough to avoid any failure.

Can You Drive with A Broken Strut Mount?

It is not recommended to drive with a broken strut mount, which can be dangerous. A broken strut mount will affect the stability and handling of your vehicle, leading to potentially hazardous driving conditions.

Here are the reasons why driving with a broken strut mount is risky:

• Reduced Suspension Functionality: If the strut mount is broken, the strut assembly will be loose or misaligned, and then the suspension system can’t absorb shocks and keep the tire in touch with the road surface as it should. So, the ride quality will be rough and unpredictable.
• Increased Risk of Further Damage: If you keep driving with a broken strut mount, it will cause damage to other suspension components, such as the struts, springs, and other mounting hardware. Then you’ll need to repair them all, which costs you more.
• Handling and Control Issues: A broken strut mount can affect the handling and control of the vehicle, making it difficult to steer, unstable, and poor in braking performance. It may cause accidents, especially when you make emergency maneuvers or drive in bad conditions.
• Tire Wear Uneven: A compromised suspension system can cause tire wear, reduce the lifespan of the tire, and compromise traction and handling.
• Safety Concerns: Driving with a broken strut mount will compromise the overall vehicle safety. In case of sudden maneuvers or impacts, such as potholes or bumps, the suspension system may fail to absorb the shocks, which will increase the risk of loss of control and accidents.

How Much Does It Cost to Replace a Strut Mount?

The cost of replacing a strut mount varies by different factors, such as the vehicle’s make and model, the location of the repair shop, and whether you only replace the strut mount or the whole strut assembly.

Here’s a general cost analysis:

• Parts Cost:
  • A single strut mount usually costs $20 to $100.
  • If you replace the whole strut assembly (including the strut, spring, and mount), it can cost $150 to $400 per assembly.

• Labor Cost:
  • The labor cost for replacing a strut mount is usually about $100 to $300, depending on the complexity of the job and local labor rates.

• Total Cost:
  • Replacing a single strut mount usually costs $120 to $400.
  • Replacing the whole strut assembly on both sides of the vehicle can cost $400 to $1,200.

Prices may vary depending on the location and the repair shop. The luxury or high-performance vehicles may be higher. You’d better ask your mechanic to give you an estimate in details before you decide to repair it.

What Are The Symptoms of A Bad Strut Mount?

It is important to notice the failure of the strut mount in advance. Here are some common symptoms of a bad strut mount:

• Unusual Noises:
  • Clunking or Knocking: You might hear clunking or knocking noises, especially when driving over bumps or uneven surfaces.
  • Squeaking: A worn-out strut mount can produce squeaking sounds during turns or while driving on rough roads.

• Steering Problem:
  • Hard to Steer: You may find it harder to turn the vehicle smoothly, for there is increased resistance or stiffness in the steering wheel.
  • Wandering: The vehicle may drift or pull to one side, indicating that the strut mount fails to hold the strut in place.

• Vibrations:
  • Steering Wheel Vibration: A defective strut mount may result in steering wheel vibration, especially at high speed or turning.
  • Cabin Vibration: You may feel more vibrations in the cabin, which makes the ride less comfortable.

• Uneven Tire Wear:
  • Tire Wear Patterns: Uneven tire wear can occur if the strut mount is not maintaining proper alignment, leading to excessive wear on certain parts of the tire.

• Visible Damage:
  • Cracks or Wear: When you check it visually, you may find cracks, corrosion, or excessive wear on the strut mount, which means it should be replaced.

• Uncomfortable Riding Experience:
  • A worn strut mount will make your ride more uncomfortable and bumpy because it can’t absorb the shocks from the road properly.

If you experience any of these symptoms, please ask a qualified mechanic to check your car.
