BMW 640i Strut Assembly Replacement at your home or office.

What is the Strut Assembly all about?

The strut assembly, an essential part of your car's suspension system, is attached to the front wheels and is used to absorb road shock, providing a smooth ride. Most cars made after 1995 have shock absorbers in the rear and strut assemblies in the front suspension. Older cars may have shock absorbers at all four wheels. Faulty or damaged struts affect the ride comfort as well as the braking effectiveness.

The strut assembly, located in the front or rear of the car, is basically a shock absorber with a spring coil for additional support. The front wheels have the extra weight of the engine and need extra support to absorb shock from the road. The shock absorber has a piston and a cylinder that contains a gas or liquid substance. The spring is attached to the piston. When you drive over a bump, the piston inside the cylinder moves up and down against the gas/fluid and the spring, absorbing the shock from the bump.

The strut assembly takes a beating over time, especially on bumpy roads. It will eventually start leaking the gas/liquid, leaving you with an unstable or rugged ride. With worn out struts, it is possible that the tires could lose contact with the road and/or the tires will wear out prematurely.
