Do I Put Loctite on Suspension Control Arm Bolts?
Introduction
Hey readers! In the world of automotive maintenance, working on the suspension system is not for the faint of heart. This system is responsible for keeping your car’s wheels firmly planted and navigating various road conditions. Among its many components, suspension control arm bolts play a crucial role in ensuring your vehicle’s handling and safety. But the question arises: Do I need to apply Loctite to these suspension control arm bolts? Let’s dive into the details to unravel the answer.
Understanding Loctite and Its Purpose
Loctite is a brand name for a range of adhesives specifically designed to prevent nuts and bolts from loosening due to vibration or other forces. It comes in various strengths, from low to high, and can be applied to metal surfaces to create a secure bond. In the context of automotive maintenance, Loctite has become a popular choice for securing various bolts and fasteners, including those on suspension control arms.
When to Use Loctite on Suspension Control Arm Bolts
Now, let’s address the main question: Should you use Loctite on suspension control arm bolts? The answer is a resounding yes in certain situations. Loctite is particularly beneficial in the following scenarios:
1. High-Stress Applications
Suspension control arms are subjected to significant stress and vibration during driving. Using Loctite on these bolts helps to prevent them from coming loose and compromising the suspension’s integrity. This is especially crucial in off-roading or racing applications where the suspension undergoes even more extreme forces.
2. Loose Bolts
If you notice that your suspension control arm bolts have become loose, applying Loctite can prevent further loosening and ensure a secure connection.
3. Rust and Corrosion
In areas prone to rust and corrosion, Loctite can act as a barrier against moisture and prevent the bolts from seizing up.
When Not to Use Loctite on Suspension Control Arm Bolts
While Loctite offers several benefits, it’s not suitable for all situations. Avoid using Loctite on suspension control arm bolts if:
1. Overtightening Risk
Applying Loctite to suspension control arm bolts can increase the risk of overtightening. Overtightening these bolts can lead to thread damage or even breakage.
2. Future Maintenance
Using Loctite on suspension control arm bolts can make it difficult to remove them in the future if necessary. This can be problematic if you need to make adjustments or perform repairs.
Types of Loctite for Suspension Control Arm Bolts
If you decide to use Loctite on your suspension control arm bolts, selecting the appropriate strength is essential. Loctite offers different grades of thread lockers, each with varying levels of holding strength:
| Grade | Strength | Application | Removal Difficulty |
|---|---|---|---|
| Blue (242) | Low | General purpose, can be disassembled with hand tools | Easy |
| Red (271) | Medium | Permanent, requires heat or special tools to remove | Difficult |
| Green (290) | High | High-strength, recommended for high-torque bolts | Very difficult |
Application Instructions for Loctite
If you choose to apply Loctite to your suspension control arm bolts, follow these steps carefully:
- Clean the bolts and threads thoroughly. Remove any dirt, grease, or rust using a wire brush or brake cleaner.
- Apply Loctite sparingly to the male threads. Avoid getting it on the bolt head or female threads.
- Tighten the bolt to the specified torque. Refer to your vehicle’s repair manual for the correct torque specifications.
- Allow the Loctite to cure. The curing time may vary depending on the specific type of Loctite used.
Conclusion
So, do you put Loctite on suspension control arm bolts? The answer is yes, but only in certain situations, such as high-stress applications, loose bolts, or rust-prone environments. Selecting the appropriate type of Loctite and applying it correctly is crucial to ensure a secure connection while maintaining the ability to remove the bolts in the future if necessary.

FAQ about Loctite on Suspension Control Arm Bolts
Do I need to use Loctite on suspension control arm bolts?
Yes, it is recommended to use Loctite on suspension control arm bolts to prevent them from loosening due to vibration and stress.
What type of Loctite should I use?
Use a medium-strength threadlocker, such as Loctite Blue 242 or Loctite Red 271.
How much Loctite should I apply?
Apply a small drop of Loctite to the threads of the bolt. Do not overtighten the bolts.
Do I need to clean the bolts before applying Loctite?
Yes, clean the bolts with a degreaser or rubbing alcohol to remove any dirt or oil that could interfere with the Loctite’s adhesion.
How long does it take for Loctite to cure?
Loctite Blue 242 typically cures within 24 hours, while Loctite Red 271 cures within 12 hours. Allow the Loctite to fully cure before driving the vehicle.
Can I use Loctite on all suspension bolts?
No, do not use Loctite on bolts that require precise torque settings, such as the axle castle nuts or strut mounting bolts.
What are the risks of using too much Loctite?
Applying too much Loctite can make it difficult to remove the bolts in the future.
What are the risks of using too little Loctite?
Using too little Loctite may not provide enough holding power, allowing the bolts to loosen.
Can I use alternative threadlockers instead of Loctite?
Yes, you can use other threadlockers, such as Permatex or Vibra-Tite, as long as they are medium-strength and suitable for automotive applications.
