Do Struts need to be replaced? Some people would say no, but in all honesty I personally prefer a smooth ride. It could also be a matter of safety. If experiencing a bumpy ride, or the Steering becomes stiff or harder to turn, it can also sway or lean to one side. You may also be hearing noises such as clunking or a knocking noise. The Struts and Springs are part of your Vehicles Suspension System.
They absorb all the excess bouncing of your Vehicles Suspension System. What the struts house are the Coil Spring, Spring Seats and Shock Absorbers. The Strut Bearing and the Steering Knuckle. The Struts provide the structural support – connecting the upper Strut Bearing to the lower Ball Joint. The Picture below is the Vehicle that had the Struts and Springs replaced.
