What are the shock absorbers?
Shock absorbers cushion road vibration and bumps. Located in the suspension near each wheel, they are connected to the wheel and the car frame. They are filled with oil and sometimes air or nitrogen to soften the vertical jolts by dampening the up-and-down motion of the springs (which absorb the main jolts). A different kind of shock, called the McPherson Strut, takes up less room and improves handling by combining the springs and shocks into one unit. When shocks and struts are worn, they can leak oil. Shock and strut wear can cause the vehicle to bounce up and down for too long after you hit a bump and cause tire and suspension wear.
