Identifying The Signs Of Seized Coilovers

Coilovers are an important component in a vehicle’s suspension system. Signs of a seized coilover can be identified by noticing a change in ride quality, uneven tire wear, and a knocking sound. To diagnose the condition of your coilovers, inspect them for damage and resistance.

Ignoring the signs of a seized coilover can result in further damage to the suspension, uneven tire wear, and a higher risk of tire blowouts. Regular maintenance of your suspension system is essential for optimal performance and safety. It’s recommended to check for the signs of a seized coilover during regular servicing and replace the component if necessary.

How To Unseize Coilovers : Follow the Steps

If your coilovers have seized, it can be a frustrating situation. Here are some steps you can try to unseize them:

  1. Apply Penetrating Oil: Start by spraying a good-quality penetrating oil, such as WD-40 or PB Blaster, on the threaded portions of the coilovers. Let the oil penetrate for a few hours or overnight. This will help loosen any rust or corrosion.
  2. Use Heat: If the penetrating oil alone doesn’t work, you can try applying heat to the seized areas. Use a heat gun or a propane torch to warm up the threaded portions of the coilovers. The expansion and contraction caused by the heat can help break up the rust or corrosion. Be cautious when using heat to avoid damaging any surrounding components.
  3. Apply a Rust Dissolver: If the penetrating oil and heat haven’t worked, you can try applying a rust dissolver or rust loosening agent to the seized parts. Follow the instructions on the product for the best results. These products can chemically break down rust and corrosion, making it easier to free the seized coilovers.
  4. Use a Vice Grip or Adjustable Wrench: Once you’ve treated the seized areas with penetrating oil or rust dissolver, try using a vice grip or an adjustable wrench to grip the threaded portion of the coilover. Apply steady, firm pressure while attempting to rotate the coilover back and forth. Avoid excessive force as it may damage the coilover or the adjustment mechanism.
  5. Use a Coilover Adjustment Spanner: If the above methods haven’t worked, you can try using a specialized coilover adjustment spanner. This tool is designed to grip the adjustment collar on the coilover and provide better leverage. Insert the spanner into the collar and apply rotational force in both directions to loosen the seized parts.
  6. Seek Professional Help: If you’ve tried the above steps and are still unable to unseize the coilovers, it’s best to seek assistance from a professional mechanic or a specialized suspension shop. They will have the necessary tools and expertise to safely address the issue without causing damage.

Remember to exercise caution throughout the process and avoid using excessive force, as it can lead to further complications.

Preventing Seized Coilovers

Regular maintenance and inspection are essential to prevent seized coilovers. The lifespan of your coilovers can be prolonged by maintaining them properly. Here are some tips and tricks that can help you prevent coilover seizing. Firstly, keep them clean and well-lubricated to avoid rust and corrosion.

Secondly, ensure that they are tightened properly and the adjustments are correct. Lastly, avoid harsh impacts and rough driving conditions.

Frequently Asked Questions Of How To Unseize Coilovers

How Do You Unseize Coilovers?

To unseize coilovers, first, apply lubricant to the seized portions and let it sit. Next, use a coilover spanner to adjust the coilover spring, but don’t overtighten it. Then, carefully loosen the collar with the spanner or a hammer and pry bar.

Finally, clean the thread with a wire brush.

What Causes Coilovers To Seize?

Coilovers can seize due to rust, dirt, and moisture accumulation. Continuous environmental exposure such as road salt, grime, and dirt can cause coilovers to stick. Additionally, excessive tightening or the use of incompatible parts can also cause coilovers to seize.

Can I Drive With Seized Coilovers?

It is not recommended to drive with seized coilovers as it poses a safety risk. Seized coilovers can cause damage to other suspension components and can cause an unstable ride. It is best to have seized coilovers repaired or replaced before driving the vehicle.

How Often Should I Maintain My Coilovers?

It is best to check the condition of your coilovers periodically, especially if you live in areas with harsh weather conditions such as snow, salt, and moisture. Ideally, check your coilovers every six months or after every 10,000 miles to ensure they are in good working condition.

Can I Prevent Coilover Seizing?

Coilover seizing can be prevented by applying lubricant to the coilover threads. Additionally, washing and cleaning your car’s undercarriage regularly can prevent damage accumulated over time. Use anti-seize or brake grease on fittings during installations to prevent rust and corrosion.

Conclusion

To sum it up, unseizing coilovers can be a daunting task, but it is not impossible. With the right tools, knowledge, and techniques, you can easily unseize your coilovers and get your vehicle back on the road in no time.

Remember to always use protective gear, follow safety protocols, and approach the task with caution. Don’t rush the process and take your time to ensure precision in every step. Regular maintenance and inspection of your coilovers go a long way in preventing seizing, so make sure to prioritize these practices.

Lastly, if you’re not confident in doing the task yourself, seek the help of a professional mechanic. By following these tips, you can have a smooth and hassle-free driving experience.
