What are the parts of a strut assembly?
A strut assembly consists of two primary elements: the coil spring, which supports the height, weight and stability of the vehicle; and the shock absorber, which swallows bumps and dampens vibrations caused by irregularities on the roadway. Other components of the strut geometry include the spring seats, the strut bearing, and the steering knuckle.

Struts are important to overall vehicle operation because they are integral to both the suspension and the steering systems. In addition to general ride quality and load-bearing support, they impact brake performance, wheel alignment, and turning ability.
