What is a Suspension Strut?

Most modern passenger cars have a suspension system that uses a combination of shocks and struts. Most commonly, shock absorbers are used in the rear of the vehicle, while strut assemblies are used in the front.

Suspension strut assemblies are an integral part of the vehicle’s structure, combining the strut, strut mount, and coil spring into one unit. For many vehicles these components can be purchased in a pre-assembled Strut Assembly Kit.

How Long Should Suspension Struts Last?

Most vehicle’s struts are filled with hydraulic fluid and/or nitrogen gas, and over time these can leak out through cracked or worn seals. When this happens, you will probably notice a change in your vehicle’s suspension, ride height, and handling.

Because there are so many variables, there is no real guideline for how long a suspension strut should last. It is recommended that you take a look at your vehicle’s struts any time the other front end components are being inspected, like tie rod ends, stabilizer bar links, and ball joints. Most of the time when a strut fails you will begin to notice a change in the steering and ride quality.
