Suspension bushings are an important part of a vehicle’s suspension system. They are located at the points where your suspension components connect to your chassis. One of their purposes is to reduce the amount of vibration and noise that is transferred from the suspension to the rest of the vehicle, and another is to absorb impact from bumps in the road.
Suspension bushings are made from a variety of materials, including rubber, polyurethane, and metal. While they all serve the same basic purpose, each material has its own unique benefits and drawbacks.
Rubber suspension bushings are the most common type, and they offer good resistance to vibration and noise. However, they can become soft and compliant over time, which can cause them to fail prematurely.
Polyurethane suspension bushings are much stiffer than rubber bushings, and they do not degrade as quickly. However, they can be more difficult to install, and they may transmit more noise and vibration than rubber bushings.
Metal suspension bushings are the most durable type, but they can also be the most difficult to install. In addition, they may transmit more noise and vibration than other types of suspension bushings.
Suspension Bushings can fail for a number of reasons. Here are four of the most common causes of suspension bushing failure:
Wear and Tear
Just like any other suspension component, suspension bushings can wear out over time due to normal usage. This is especially true if the vehicle is driven on rough roads or used for off-road activities. Over time, suspension bushings can wear out, becoming cracked and brittle.
This wear can cause increased vibration and noise, as well as poor handling and reduced suspension travel. In extreme cases, suspension bushings can fail completely, leading to suspension failure and possibly a vehicle accident.
Because suspension bushings play such an important role in safety, it is important to inspect them regularly and replace them as needed. By doing so, you can help ensure that your vehicle will continue to ride smoothly and safely for years to come.
Corrosion
Suspension bushings can also fail due to corrosion, especially if they’re made of metal. Corrosion is the result of a chemical reaction between the metal and the environment. When suspension bushings are exposed to moisture, they can become corroded.
In addition, suspension bushings can also become corroded if they are exposed to salt or other chemicals. Once corrosion starts, it can spread quickly, causing the suspension bushing to become brittle and break.
To prevent suspension bushings from becoming corroded, it is important to keep them clean and dry. If they become wet, it is important to dry them off as soon as possible. In addition, it is important to avoid exposing them to salt or other chemicals. By taking these precautions, you can help to ensure that your suspension bushings will last for many years.
Loose Bolts
If the suspension bushings are not properly secured, they can become loose and eventually fail. This is usually due to improper installation or simply due to age and wear. This is why it’s important to consult a certified Subaru mechanic to perform all replacements and repairs on your car.
Impact and Collision
A suspension bushing can also fail if it’s impacted by a hard object, such as a rock or pothole. This type of failure is usually obvious, as the bushing will be visibly damaged.
If you suspect that your suspension bushings are failing, it’s important to have them inspected by a qualified mechanic. Suspension bushings are an important part of your vehicle’s suspension system and can affect the handling and ride quality of your vehicle. If they’re not in good condition, it’s important to have them replaced.
