Leaf Springs Got Ya’ Down? – Grease Em Up!!!

How to grease your leaf springs

My Rubicon lift relies on the age-old “add-a-leaf” idea. Ever since I took apart the factory Leaf Springs, and upset the bushings, they have creaked, groaned, and made more darn noise than the stereo on the inside. Soooo I once again decided to put the beast up on stands and take ‘er apart.

Jeep’s leaf springs are an integral part of its suspension system. They provide support and help absorb shocks when driving off-road or on uneven terrains. Regular maintenance of the leaf springs is essential to ensure optimal performance and longevity of your Jeep. One crucial aspect of leaf spring maintenance is greasing. In this article, we will guide you on how to grease Jeep’s leaf springs effectively.

Understanding Leaf Springs

Leaf springs are long, curved metal bars or strips that are stacked on top of each other. They are attached to the axle and the chassis of the vehicle. The purpose of leaf springs is to distribute the weight of the vehicle evenly and provide stability and support. They also help absorb shocks and vibrations, ensuring a smoother ride.

Importance of Greasing Leaf Springs

Greasing the leaf springs is vital to prevent friction and wear between the individual leaves. Over time, dirt, dust, and moisture can accumulate between the leaves, leading to corrosion and reduced flexibility. By applying grease, you create a protective barrier that reduces friction, minimizes wear, and extends the lifespan of the leaf springs.

Tools and Materials Needed

Before you begin greasing your Jeep’s leaf springs, gather the following tools and materials:

  • Floor jack and jack stands
  • Wheel chocks
  • Wrench or socket set
  • Wire brush
  • Grease gun
  • High-quality lithium or synthetic grease
  • Rag or shop towels


Step-by-Step Guide to Greasing Jeep’s Leaf Springs

Prepare the Jeep

Park your Jeep on a flat surface and engage the parking brake. Place wheel chocks behind the rear wheels to prevent any movement. Use a floor jack to lift the rear end of the Jeep and secure it on jack stands for safety.

Put the Jeep Up on Stands

I started by pulling the studs out just like you were taking the spring out…

Pulling Out the Leaf Springs Studs

The grease I used was a wheel bearing grease and is nice and thick. Use any grease you want as long as it’s not watery.

!!!!!DO NOT USE WD-40!!!!!

Once you pull the springs down and the bushings are exposed. Lube them up like it’s your job. As shown here the shackle gets a face full of grease(those were some squeaky bastards…)

Clean the Leaf Springs

Use a wire brush to remove any dirt, rust, or debris from the surface of the leaf springs. Pay close attention to the areas between the leaves. Ensure that the springs are clean and free from any contaminants.

Lube the Bushings of Your Leaf Springs

Load the grease gun with high-quality lithium or synthetic grease. Apply grease to the surface of each leaf spring, focusing on the areas where the leaves come into contact. Make sure to apply an even coat of grease, covering the entire length of the leaf springs.

This is what it looked like after I got done doing the sliming. Nice and clean to a point. Don’t overdo it because at that point you are just wasting it.

Put the Leaf Springs Studs Back

After greasing the leaf springs, carefully lower the Jeep off the jack stands using the floor jack. Remove the wheel chocks and take the Jeep for a test drive to ensure that the leaf springs are functioning smoothly.

Afterward, I drove around the block, and to my amazement…It sounds so much better. It made no noise at all!!! Finally some peace and quiet.

Tips for Effective Greasing

  • Regularly inspect your Jeep’s leaf springs for signs of wear, damage, or corrosion.
  • Follow the manufacturer’s recommendations regarding the type and frequency of greasing.
  • Use a high-quality lithium or synthetic grease that is suitable for automotive applications.
  • Apply grease evenly and generously, ensuring complete coverage of the leaf springs.
  • Clean and remove any excess grease from the surrounding components to avoid attracting dirt and debris.


Can I grease my Jeep’s leaf springs without lifting it?

While it is possible to grease the leaf springs without lifting the Jeep, it is recommended to lift the rear end for easier access and better visibility.

How often should I grease my Jeep’s leaf springs?

The frequency of greasing depends on various factors, including your driving conditions and the manufacturer’s recommendations. As a general guideline, greasing every six months or every 10,000 miles is a good starting point.

What type of grease should I use for my Jeep’s leaf springs?

It is best to use a high-quality lithium or synthetic grease specifically designed for automotive applications. These greases offer excellent lubrication and protection against corrosion.

Can I over-grease my leaf springs?

Over-greasing can lead to excessive buildup and attract dirt and debris. Apply enough grease to create a protective barrier without leaving excess grease.

Should I grease both sides of the leaf springs?

Yes, it is important to grease both sides of the leaf springs to ensure even lubrication and prevent uneven wear.


Properly greasing your Jeep’s leaf springs is essential for maintaining a smooth and comfortable ride, as well as prolonging the lifespan of the suspension components. By following the step-by-step guide provided in this article and adhering to regular maintenance intervals, you can ensure that your Jeep’s leaf springs perform optimally in various driving conditions.

Don’t neglect this important maintenance task. Grease your Jeep’s leaf springs regularly and enjoy a more capable and reliable off-road experience!
