What's the best solution for strut mount replacement?

What is a strut mount?

Strut mount also known as shock absorber mount, it’s plays a key role in providing a smooth and comfortable ride. It is a mounting point for the top of the strut, which is a key part of the suspension system that helps to absorb shocks and vibrations from the road surface. The strut mount is typically made of rubber or metal and is designed to provide a secure attachment point for the strut while also allowing for some degree of movement and flexibility. This flexibility is important as it allows the strut to move up and down in response to changes in the road surface, helping to maintain stability and control of the vehicle. In addition to providing a secure attachment point for the strut, the mount also helps to isolate the cabin of the vehicle from road noise and vibrations, further enhancing the overall comfort of the ride.

Many front strut mounts also contain a bearing which acts as a steering pivot – so as you turn the steering wheel from left to right and vice versa, the strut pivots on the strut mount, controlling the angle and alignment of the wheels.

Symptoms of a defective strut mount

Like most other parts, there are a few tell-tale signs of a faulty strut mount. If your customer complains of any of the following, the top strut mount could be at fault:

1. Abnormal noises coming from the steering and suspension system.

Knocking or clunking noise coming from the front end of the vehicle or squeaking when maneuvering at low speed. This noise is typically heard when driving over bumps or rough roads, and is caused by the strut mount becoming loose or worn out. In some cases, the noise may also be accompanied by a feeling of looseness or instability in the steering wheel, indicating that the strut mount is no longer able to properly support the strut.
Premature and/or uneven tire wear

2. Accelerated wear of shock absorbers

When the strut mount is defective, it can cause excessive movement and vibration, putting additional strain on the shock absorbers. This accelerated wear can result in reduced handling capabilities, increased braking distances, and a rougher ride quality.

3. Excessive vibration

Excessive vibration caused by a defective strut mount is a common issue that can significantly affect the performance and safety of a vehicle. The strut mount plays a crucial role in connecting the suspension strut to the vehicle’s chassis, and when it is faulty or worn out, it can lead to increased vibration and noise while driving.

4. Poor wheel/tire alignment

The strut mount plays a crucial role in maintaining the proper alignment of the wheels and tires, as it connects the strut to the vehicle’s chassis. When the strut mount is defective, it can cause the wheels to become misaligned, leading to uneven tire wear, poor handling, and decreased overall performance.

4. Poor steering return

This can occur when the strut mount is damaged or worn out, causing the strut to move around more than it should. As a result, the vehicle may feel less stable on the road and the steering may become more difficult to control. In severe cases, the vibration can become so intense that it affects the overall handling and safety of the vehicle.

5. Visual inspection

As well as these common symptoms, a good visual inspection will help to identify possible wear or damage. Look for any signs of corrosion, cracks or tears in the rubber, separation from the metal and excessive movement in the strut assembly. Also check the steering pivot to ensure smooth and free rotation.

In conclusion, in addition to normal noise and vibration, a faulty strut mount can also cause uneven tire wear. When the strut mount is not functioning properly, it can lead to misalignment of the suspension system, which can cause the tires to wear unevenly. This can result in decreased traction and handling, as well as reduced fuel efficiency. If left unaddressed, uneven tire wear can lead to more serious issues such as tire blowouts or premature tire failure.

Furthermore, a faulty strut mount can also affect the overall performance of the vehicle. When the strut mount is not functioning properly, it can cause the strut to become misaligned, leading to poor handling and stability. This can make it more difficult to control the vehicle, especially during sudden maneuvers or emergency situations. In extreme cases, a faulty strut mount can even cause the vehicle to become undriveable, putting the driver and passengers at risk of an accident.

When to replace the defective strut mount?

Although not part of the routine service schedule, you should regularly check the top strut mounts and, where necessary, replace in pairs – left and right sides – as soon as possible. As well as affecting steering response and driver comfort, worn or damaged top strut mounts can have a knock-on effect on other parts of the steering and suspension system such as shock absorbers and tires, accelerating wear and causing unnecessary expense for the vehicle owner.

Also, because the top strut mount is essentially a low-cost part, in what is often a very labor intensive process, it makes sense to fit new ones whenever you’re replacing the struts. Either way, in most cases, you’ll have to remove the strut and decompress the coil spring, so it could save you from having to do the same job twice.

Why replace in pairs?

When it comes to maintaining and repairing a vehicle, it is important to consider the overall performance and safety of the vehicle. One aspect of vehicle maintenance that is often overlooked is the replacement of strut mounts. and replacing them in pairs is highly recommended for several reasons.

Because top strut mounts will typically endure the same number of miles and road conditions, chances are if one side is worn, the other will be too. It’s therefore advisable to replace in pairs – left and right side.

Replacing strut mounts in pairs ensures that both sides of the vehicle have equal support and stability. The strut mount is responsible for connecting the strut to the vehicle’s chassis, providing a stable and smooth ride. If one strut mount is worn or damaged, it can cause uneven wear and tear on the suspension system, leading to poor handling and a rough ride.

Additionally, replacing strut mounts in pairs can help to improve the overall performance of the vehicle. When both sides of the suspension system are in good condition, you can ensure their performance is evenly matched across the axle for a balanced ride height and equally responsive steering and handling. This can lead to a more comfortable driving experience and increased safety on the road.
