Understanding Coilovers Squeaking: Causes and Impact

Lack of Lubrication

  • Coilovers consist of various moving parts that require proper lubrication to function smoothly. 
  • If the lubrication diminishes or dries out over time, it can result in metal-on-metal contact and squeaking noises. 
  • Insufficient lubrication can occur due to neglecting regular maintenance or using the wrong type of lubricant.

How to Grease and Handle Your Coilovers?

Worn Bushings

  • Coilovers contain rubber or polyurethane bushings that cushion between different suspension components. 
  • These bushings can wear out over time due to constant movement and exposure to the elements. 
  • When the bushings deteriorate, they can cause friction and squeaking sounds.

Damaged or Misaligned Springs

  • The coil spring’s function is to absorb shocks and vibrations. 
  • Still, they can become damaged or misaligned due to rough road conditions or aggressive driving. 
  • A damaged or misaligned spring can create uneven pressure and rub against other suspension parts, resulting in squeaking noises.

Loose or Worn Suspension Components

  • Coilovers connect to various suspension components, such as control arms, sway bars, and end links. 
  • Suppose any of these components become loose or worn out. 
  • In that case, it can introduce excess movement and friction, leading to squeaking noises.

Environmental Factors

  • Coilovers expose to various environmental factors, including dirt, moisture, and road debris. 
  • Over time, these elements can accumulate and cause corrosion or build-up on the coilover components, resulting in squeaking sounds.

Improper Installation

  • Suppose the coilovers installation is wrong or the mounting hardware isn’t tight correctly. 
  • In that case, it can cause vibrations and rubbing, leading to squeaking noises. 

Age and Wear

  • As with any mechanical component, coilovers have a lifespan.
  • Over time, the constant compression and rebound of the coil spring, along with exposure to road conditions, can cause wear and tear. 
  • Aging coilovers may develop squeaking sounds as a result.

Resolving Coilover Squeaking: DIY Troubleshooting Methods

  • Start by inspecting the coilovers for any signs of dried or inadequate lubrication. Apply a suitable lubricant to all moving parts per the manufacturer’s recommendations.
  • The bushings may contribute to the squeaking noise if worn, cracked, or damaged. Replace them with new ones made from high-quality rubber or polyurethane.
  • If the springs are damaged, replacing them with new ones specifically designed for your vehicle’s make and model is recommended.
  • Use a brush or cleaning cloth to remove any debris, especially from areas where the coil spring contacts other parts of the suspension. 
  • Ensure that no foreign objects are in between components.

FAQs of Coilovers Squeaking

How often should I lubricate my coilovers?

The frequency of lubrication depends on factors such as driving conditions, mileage, and the manufacturer’s recommendations. Inspecting and lubricating the coilovers during regular maintenance intervals or when you notice signs of squeaking or dryness is generally advisable.

Should I replace both coilovers if only one is squeaking?

While it’s not necessary to replace both coilovers if only one is squeaking, it’s essential to diagnose the exact cause of the squeak to avoid unnecessary replacements. If the issue isolates to one coilover, focus on troubleshooting and resolving the problem specific to that unit.

 Are squeaking coilovers dangerous?

Squeaking coilovers are typically not dangerous from a safety standpoint, but they can affect driving comfort and indicate underlying issues. Ignoring squeaking noises for an extended period may lead to more significant problems and compromise the overall performance of the suspension system.
