6 Signs of a Bad Strut Mount and Their Replacement Cost

Although it is not as well-known, the strut mounting of your vehicle is an essential component to its suspension system. Bad strut mounting can result in unexpected effects and can make a car unsafe.

This article examines the function of the strut mounting, the place it is located and the consequences for its failure. Also, we examine the cost of replacing a damaged strut mounted. Let’s take a quick look at the signs first.

Strange sounds coming from your suspension when you drive, particularly if it occurs while turning the wheel, is the most obvious sign of a defective strut mounting. Check your tires for uneven wear. You may have trouble steering in some instances.

Here’s a more detailed list of the most common symptoms of a bad strut mount:

Bad Strut Mount Signs

1. Strange Sounds

Suspension Noise

You don’t want to hear squeaking or clunking noises coming from the suspension system, but that’s exactly what occurs when the strut mount wears out. The front strut mountings might make more noise when you turn the steering wheel.

This is caused by metal parts rubbing against each other or when the coil spring moves out of its place. This is because these components are susceptible to making noises when they fail without insulation. 

If you hear a “boink” noise from the front suspension when you turn the steering wheel, it’s a strong sign that the strut mount is worn. You should also inspect it for a damaged coil spring.

2. Uneven Tire Wear

Uneven Tire Wear

There are many things you could do to cause uneven tire wear. Your vehicle may just require a wheel alignment. 

But this could also be a sign that the strut mounteds are failing. This is why uneven wear occurs. 

3. Vibration Increased

Good strut mountings contain rubber insulation. The rubber may be worn out, which can cause vibrations to your car.

Strut mounts are required for insulation of metal parts. This insulation is essential to prevent vibrations from making the drive uncomfortable. 

4. Steering Trouble

A few cars have the strut mounting double-duty and can be used to pivot the steering wheel. If the mount fails in these cars, it’s going to affect the way the steering operates. 

This could affect the steering response time and smoothness. Suspension issues and steering problems should not be overlooked, particularly if you have to deal with them both. 

5. Corrosion/Wear

Metal is the most common material used to make rut mounting. Mounts made of metal can corrode, particularly if they are exposed to excessive wear. 

The rubber inside the mount acts as an insulation. The rubber will crack or become disintegrated and you'll need to replace it. If either one of these issues is the cause, a physical inspection can reveal it. 

6. Increased Movement

The strut mounting is designed to absorb road imperfections under normal circumstances. It’s designed to cushion the blows from potholes and other bumps. 

When the strut mounting fails, the mount loosens and cannot hold the struts together. This causes excessive vehicle bounce as well as additional movement during driving. 

Strut Mount

Strut Mount Location

The strut mount is attached exactly where it sounds – on the strut of the vehicle. The strut mount connects to the vehicle's suspension strut. 

The front strut mountings may also include a bearing or plate that acts as the pivot. This doubles their functionality. For noise insulation and protection from vibrations, strut mountings are made of rubber. 

What is a Strut mount?

The strut mount attaches directly to the car on one side and the strut connects to it on the other. The rubber material between the bolts acts as insulation. 

The mount is pushed against any imperfections or bumps the vehicle may encounter. This pushing and pulling force is cushioned and absorbed by the mount so that the noise and effect are minimal within the vehicle.

With an attached bearing, front struts may also be used as part of the steering mechanism. One on each side serves as a steering pivot, which is necessary for smoother travels and quicker responses. 

What Makes Strut Mounts Fault?

Struts are designed to last at least ten years under normal driving conditions. The struts can wear out if they are driven off-road, or in an environment with high humidity. Smaller accidents could also cause strut mount failure or affect the way it works. 

If you notice any usual symptoms, it’s best to have the mounts checked by a professional. These components can also be checked during routine suspension inspections. 

Strut Mount Replacement Price

A aftermarket strut usually costs between $10 and $400. The cost of an aftermarket strut is only for the part and not the professional installation. The cost of the part will vary according to what car you drive and which level of performance, as well as how many pieces you order.

It is best to replace the strut mountings in pairs. These strut mounts have most likely been used for the same mileage and driven on the same roads. The chances are that one will eventually wear out and the other will soon follow. Replace both sides of the axle at once. If you replace them all together, it ensures an exact match of axles, which results in a smooth ride and responsive handling.
