Worn-out rides will make your rides a living hell as they can also cause noises such as clunking and rattling when going over bumps. You will find bushes in shock absorbers, anti-roll bars, and ball joints, and in all parts, metal is in contact with another metal in the suspension system.īecause suspension bushes are made of rubber and are in most cases subjected to strain, they often wear out quickly over time. They help reduce movement and, at the same time, minimize vibrations and noise. Faulty Suspension Bushesīushes are rubber cushions that are mounted on all joints in the suspension system. However, even though the grease can help eliminate the problem, the creaking noises could also sign a major issue. Lack of LubricationĪt times creaks in the steering system and suspensions are caused by a lack of lubrication of the metal components such as shock units and tie rods.Ī well-lubricated system helps prevent dirt build-up. Now that you know how shocks work and the different types of suspension systems, let’s look at the other causes of car suspension noises. Car Makes Creaking Noise When Going Over Bumps Causes It often connects the tires on the opposite side of the car- such that when one tire is raised higher than the other when cornering, the bar will resist the twist hence keeping the car level.Ĭlick here to read a detailed guide on how anti-roll bars work. Historically, leaf springs were common, but today, most cars use steel coil springs.įor steel coil springs, the spring is compressed when the wheel moves down and when the wheel moves up, it is stretched out.Īnti-roll bars, on the other hand, help reduce body lean when maneuvering corners. There are several types of suspension springs. If the damper/shock absorbers are damaged or worn out, you will experience a bouncy ride as the springs won’t dispose of the kinetic energy. Inside the shock absorber/damper is a piston filled with oil responsible for converting kinetic energy to heat. The dampers will take some of the kinetic energy and convert it to heat. Dependent- it uses a fixed axle- and the movement of one wheel impacts the other’s movement.Ĭomponents of Car Suspension System Shock AbsorbersĮven though the suspension system’s springs are designed to absorb kinetic energy during the compression cycle, a shock absorber/damper helps dissipate the energy by converting it to heat.Īs the spring slowly decompresses, the potential energy is then converted to kinetic energy. ![]() ![]() Independent- each wheel is capable of moving independently.There are two types of suspension system: It absorbs shocks and vibrations caused by the wheels on potholes, bumps, humps, and uneven road surfaces.Ī car suspension system comprises components that connect the tires to the main body of your automobile. It also helps maximize the friction between the tires and the road when braking, accelerating, and cruising. The suspension is designed to provide comfort while driving without compromising handling.
