Why is My Suspension Squeaking?
Squeaking suspension is not only noticeable and annoying when driving over dips, potholes, or speed bumps, but can also be a warning sign of a failing suspension component. The suspension system is responsible for keeping you comfortable as well as keeping your vehicle under control. Failing suspension can turn from a nagging issue into a dangerous scenario if left unaddressed.
Why Does My Suspension Do?
Suspension systems in cars are a set of components responsible for the way your vehicle absorbs and dissipates energy while driving, which helps keep the driver and passengers comfortable but also keeps the car planted and under control. Without the ability to properly dissipate energy, your vehicle may be more drastically affected by uneven road surfaces and sharp cornering.
What Happens When My Suspension Wears Down?
Over time, the rubber and plastic parts, hydraulic systems, and metal components all see wear and tear from everyday driving. These worn-down components can begin to make certain noises, such as squeaking, rubbing, and grinding.
These noises can happen in your suspension for a variety of reasons, such as misaligned components or ripped/worn rubber.
Five Common Causes of Noisy Suspension
Lack of Lubrication
Luckily, one of the most common causes of suspension noise is also the easiest to fix. Suspension components such as the shocks or struts or other moving parts can lose their lubrication over time and lead to an unpleasant noise over dips and bumps.
Having a trusted local mechanic apply grease and lubrication can remedy this issue.
Worn Ball Joints
The most common culprit of squeaking suspension is worn or ripped ball joints. Your car’s rubber ball joints allow your suspension components to move freely. These joints absorb much of the impact from the road, and in turn, wear down quicker than many other of the parts around it.
The rubber on the joints can begin to rip, and cause a rubbing or squeaking noise as your vehicle encounters uneven surfaces. Allowing a ball joint to completely fail can lead to the complete loss of a wheel while driving, which is extremely dangerous.
If you notice this sound from your suspension and any change in driving dynamics, you should have your suspension inspected and serviced immediately to prevent a more dangerous situation down the line.
Rubber Bushings
Your suspension uses a variety of rubber bushings to cushion impacts and absorb energy. The rubber material works great for its purpose, but as you can imagine, the rubber starts to degrade over time.
These dried, cracked, and broken bushings can lead to a rubbing or creaking sound over uneven surfaces. Applying lithium grease to bushings can help quiet them down, but a replacement will always be the recommended option.
Worn Springs
Similar to ball joints and bushings, your springs take a significant amount of impact every time you drive. With consistent use, these springs can start to wear and sag.
With weaker springs, your vehicle will encounter harder impacts and subsequently more worrying noises.
My Suspension is Squeaking! What Should I Do?
While suspension squeak can seem generally harmless and easy to ignore, it’s likely signaling a much more serious issue. Don’t let suspension issues linger. Bring your vehicle in for an inspection and service as soon as possible.
