How to Grease a Ball Joint: A Comprehensive Guide

If you have a car you are aware of how crucial maintaining it is. The ball joint is one of the most important parts of your car’s suspension system. It connects the control arm to the steering knuckle, allowing for smooth steering and suspension movement. As with any other car part, ball joints need proper maintenance to ensure they work optimally and last long. In this guide, we will show you how to grease a ball joint, a crucial step in joint maintenance. 

Understanding Ball Joints

Understanding Ball Joints

These joints are a necessary part of many different kinds of vehicles, such as cars, trucks, and SUVs. These small but critical parts are responsible for allowing your vehicle’s suspension to move up and down while keeping your wheels in line with your steering system. Understanding joints can help you diagnose issues with your suspension system and keep your vehicle running smoothly.

A joint consists of a spherical bearing and a metal socket that is attached to the control arm of your vehicle’s suspension system. The spherical bearing is enclosed in a metal housing that is filled with grease to help lubricate the joint and reduce friction. When the suspension system moves up and down, the joint allows the wheel and tire to follow the movement while remaining in line with the steering system.

Joints can become worn or damaged due to normal wear and tear, driving on rough roads, or exposure to harsh weather conditions. When this happens, the joint can become loose or fail completely, which can lead to a number of issues with your vehicle’s suspension, including uneven tire wear, a shaking steering wheel, or a vehicle that pulls to one side.

It is crucial to have your car checked out by a trained mechanic as soon as you detect a problem with your ball joints. A skilled technician can diagnose the problem and replace any worn or damaged ball joints, helping to ensure that your vehicle’s suspension system continues to operate smoothly and safely.

Tools Needed

Tools Needed
  • Grease gun – You will need a grease gun to inject grease into the joint. Make sure to choose a grease gun with a flexible hose to reach tight spots easily.
  • Grease – You will need to choose the right type of grease for your ball joint. Check your vehicle’s owner’s manual for the recommended type of grease. Lithium-based or synthetic grease is commonly used for joints.
  • Jack and jack stands – You will need to lift your vehicle off the ground to access the ball joint. A jack and jack stand will help you do this safely.
  • Wrenches – You will need a wrench to remove the zerk fitting, the small metal nipple located on the ball joint, before greasing.
  • Gloves – Grease can be messy and difficult to clean. Wearing gloves will protect your hands from getting greasy.
  • Rags – You will need clean rags to wipe off excess grease and keep your work area clean.
  • Wearing Safety Goggles – To shield your eyes from grease and particles, safety goggles are always a smart idea.

How to Inspect a Ball Joint

How to Inspect a Ball Joint
  • Locate the ball joint on the suspension. Depending on the type of suspension system, joints may be located at the top or bottom of the steering knuckle or control arm.
  • Inspect the rubber boot that covers the ball joint. Look for any signs of cracking, tearing, or damage to the boot. The rubber boot is essential in keeping dirt, debris, and moisture out of the joint, and if it is damaged, the joint is more likely to fail prematurely.
  • Check for excessive play in the ball joint. With one hand, grip the steering knuckle or control arm near the joint and attempt to move it up and down or side to side. If the joint moves excessively or feels loose, it may be worn out and need to be replaced.
  • Look for signs of wear on the joint. If the rubber boot is intact and there is no excessive play, inspect the joint itself for signs of wear. Look for any visible cracks, corrosion, or pitting on the joint. To get a better look, you might also wish to use a flashlight.
  • Check for grease. Some joints are designed to be greased regularly, while others are sealed and do not require lubrication. If the joint has a grease fitting, make sure that it has been recently lubricated and that the grease is not contaminated or dried out.
  • Repeat the inspection on the other joint(s) on the suspension.

When to Grease a Ball Joint

Ball joints are an essential part of a vehicle’s suspension system. They connect the steering knuckles to the control arms and allow for the smooth movement of the wheels.  Joints can become worn or damaged, leading to problems with steering and handling. To prevent this, it is important to regularly grease joints.

So when should you grease a ball joint? The answer to this question depends on the type of joint and the manufacturer’s recommendations. Some joints come pre-greased and do not require additional lubrication. Others may require lubrication every 12,000 to 15,000 miles or as often as every oil change.

To determine when to grease your joints, consult your vehicle owner’s manual or the manufacturer’s recommendations. You can also inspect the joint for signs of wear or damage. If the boot covering the joint is cracked or torn, or if you hear a clunking noise when turning or going over bumps, it may be time to grease or replace the joint.

Greasing a ball joint is a relatively simple process that can be done with a grease gun. First, locate the grease fitting on the joint. Then, attach the grease gun to the fitting and pump in the recommended amount of grease. It is important not to over-grease the joint, as this can cause damage.

Preparing to Grease a Ball Joint

  • Identify the ball joint: The first step in preparing to grease a joint is to locate it on your vehicle. Joints are typically found on the steering and suspension systems and can be found near the wheels or under the car’s chassis.
  • Pick the proper grease: It’s essential to select the proper grease for your joint. Most joints require a high-temperature grease that can withstand the heat generated by the joint during operation. Check your vehicle’s owner’s manual or consult with a mechanic to determine the right type of grease for your joint.
  • Make the ball joint clean: Cleaning the joint to get rid of any dirt or debris that may have formed on its surface is necessary before applying grease. Use a clean rag or a wire brush to clean the joint thoroughly.
  • Taking off the old grease: If there is old grease present in the joint, it’s important to remove it before applying new grease. A special tool called a joint press may be required to remove the old grease, so consult with a mechanic if you’re unsure how to do this.
  • Apply grease: It’s time to apply the new grease after the joint is clean and clear of the old grease. Use a grease gun to inject the grease into the joint, being careful not to overfill it.
  • Check for leaks: After greasing the joint, check for any leaks or signs of excess grease around the joint. If you notice any leaks, clean the area and reapply the grease as needed.
