Understanding Each Component of Your Suspension Set
Suspensions have gotten more and more complex over the years. Gone are the times when a simple set of leaf springs and shock would get you back up and running.
Modern suspension systems have various components, including struts, shock absorbers, stabilizer bars, control arms, and stiffer bushings. Luxury vehicles come with air and electronically-controlled strut assemblies.
Each component plays an important role in providing comfort and stability when driving on bumpy roads or around tight corners. But when one or more of these suspension parts become worn or damaged, it can lead to annoying squeaking and poor handling.
Let's go over the main suspension components to understand their function and how they function.
Struts
Struts are found in the front and rear of modern cars, but most noise issues usually arise from the front-end struts. They make up a large part of the suspension system and absorb shocks when driving on bumpy roads or over potholes.
Shock Absorbers
Shock absorbers are also known as dampers. They work with the struts to absorb impact from bumps and potholes, making for a smoother ride. Over time, this component can weaken due to wear and tear, eventually causing the vehicle to feel bouncy or squeaky.
Stabilizer Bars
Stabilizer or anti-roll bars help keep the car from rolling or swaying as it moves around corners. They also reduce body roll and increase cornering stability. When these components become worn out, they cause clunking noises when driving around sharp curves due to the rubber bushing being worn out.
Control Arms
Control arms are responsible for controlling the up-and-down motion of the wheels when driving over bumps and potholes. Over time, rubber bushings can become worn out and squeak as pressure is put on them from the road.
Other Factors to Consider
Other factors can contribute to a vehicle's squeaking besides worn-out suspension components. For instance, the shocks could be loose from a previous repair job or a suspension bracket or support may be rusted and need to be replaced. In addition, worn-out brake pads can cause squeaks when pressing down on the brakes as they rub against the rotors.
