Why is My Suspension Squeaking?

Your vehicle’s suspension should provide a smooth ride, regardless of the driving surface. However, it is normal to hear a vibration due to an uneven driving surface or rolling over stones and bumps. If your suspension is making a squeaking noise, it commonly indicates a mechanical issue.

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. If you can hear your suspension squeaking, these issues mustn’t go left unchecked, as they can lead to problems that compromise your safety on the road.

Common Reasons for a Squeaking Suspension

Lack of Lubrication

One of the most common causes of suspension noise is also the easiest to fix. Suspension components, such as shocks, struts, or other moving parts, can lose their lubrication over time leading to an unpleasant noise over dips and bumps. It’s in your best interest to have a trusted local mechanic apply grease and lubrication to remedy this issue.

Ball Joints

Ball Joints are crucial parts of your suspension system that can move in multiple directions to support the range of motion in your vehicle since they allow the wheels to move freely and bear much of the work. They’re prone to wear and tear, and when ball joints wear out, it creates spaces inside the socket. One of the signs of a worn ball joint is squeaking or clunking.

Suspension Bushings

Bushings are vital components made of rubber or other materials that are flexible within the suspension and steering systems. Commonly found in the control arms, tie rods, stabilizer bars, ball joints, strut mounts, and shock absorbers, these rubbery materials control movement in the joints by cushioning your vehicle from vibrations and protecting the metal joints from friction. If bushings dry up or crack, you’ll notice issues like squeaking noises and poor handling.

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. Springs are connected to struts and primarily absorb shock by taking on the brunt of the shock absorber through fluid movements, but they may break down at any time. With weaker springs, your vehicle will encounter harder impacts and subsequently more worrying noises.

Shock Absorbers

Shocks and struts are essential parts of the suspension system. These components are designed to absorb the impact of bumps and uneven road surfaces, ensuring a comfortable ride. However, over time, the seals within shocks and struts can wear out, causing the internal fluid to leak and reducing their effectiveness, potentially causing them to squeak. Dirt and debris may also cause squeaky shocks.

Environmental Factors

Environmental factors can also contribute to squeaky suspension. Dirt, grime, and moisture can accumulate on suspension components, leading to increased friction and noise. Regular cleaning of the undercarriage and suspension parts can help prevent this buildup and reduce squeaking.

Benefits of Fixing a Squeaky Suspension

If your suspension is squeaking, getting a repair is vital for your safety and comfort while driving on the roads.

• Cut repair costs
• Improve braking efficiency
• Better stability while driving
