Almost every vehicle that has front wheel-drive uses car struts on the front.  They aren’t just shock absorbers.  They integrate many different suspension parts into one assembly.  Included are the spring seats, coil spring, shock absorbers, steering knuckle, and strut bearing.

The shock absorber is the part of the strut that is commonly serviced the most.

The strut has many different purposes that it serves.  Because of the spring, the strut can support the vehicle’s weight while it’s traveling and allows for adaptations of road irregularities.  The shock absorber that is internal will dampen the spring’s movement while it is compressing and rebounding.

The function of the strut housing is structural.  It connects the bearing in the upper strut to the ball joint down below.  This allows the whole assembly to pivot as someone turns the steeling wheel.

It is a good idea to have your vehicle’s suspension system checked by a service technician that is qualified.  The struts in a car should be checked once a year, along with the alignment of wheels.  You never know when car parts will wear out, so an auto warranty, as well as regular maintenance is a necessary part of your routine.
