Worn Car Shock Absorbers: Warning Signs, How To Check Them Yourself, And When To Replace Them

Does your car keep bouncing after a speed bump, or are the tires wearing unevenly? Your shock absorbers may be getting weak. Learn the signs, a simple way to check them, and the right time to replace them.

Shock absorbers rarely get attention until the car starts to feel uncomfortable. Yet this part is not only about a soft or firm ride. Weak shock absorbers keep the tires from gripping the road properly, so braking distances can get longer and the car feels less stable when maneuvering, especially on bumpy or wet roads.

The way a shock absorber works is simple. The spring carries the weight of the car, while the shock absorber damps the spring's up-and-down movement using oil or gas inside its tube. With use, the seals wear, oil seeps out, and the damping slowly fades. Because the decline is gradual, many drivers never notice and assume the car has always ridden that way.

Signs Your Shock Absorbers Are Getting Weak

- The car keeps bouncing up and down after a speed bump or pothole instead of settling right away. - The body feels floaty or leans too much in corners and when changing lanes on the highway. - The front of the car dives hard under braking while the rear lifts. - You hear a clunking or knocking sound from the suspension on rough roads. - The tires wear unevenly, with a wavy or cupped pattern at several spots on the tread. - There is oil seeping on the shock absorber body or around its rubber boot.
