Complete ball joint failure is rare, but it does happen. A more common problem is wear and tear on the joint from continual driving over uneven and bumpy road surfaces. A worn ball joint can significantly affect your suspension and steering, and these can have a range of knock-on effects that can affect your vehicle, your driving, and potentially your safety. Should the joint fail completely, then the results can be catastrophic, including the wheel quite literally falling off your vehicle. The best way to avoid this is to replace the ball joint as soon as you notice the effects of wear. While the ball joint is relatively easy to replace, the problem is finding the right ball joint for your vehicle. Our panel of automotive experts is here to help. They have compiled a list of the best ball joints to point you in the right direction.

Best Ball Joints Buying Guide & FAQ

Regular maintenance is one of the best ways of getting the most from your vehicle in terms of performance and longevity. However, even the best maintained car will have parts that eventually succumb to wear and tear, particularly if you spend a lot of time on poorly maintained roads or driving off-road. One part that can suffer in these conditions is the ball joint, and this can have a detrimental effect on your steering. When it comes to replacing this part, it is essential to get the right replacement. In this part of the buying guide, our panel of experts take you through the things you need to consider when buying ball joints for your car, the different types of ball joints that are available, and the best ball joint brands. We also answer some of the most frequently asked questions about ball joints.

Things to Consider When Buying Ball Joints for Your Car

The most important thing to consider when buying ball joints for your car is whether the part is suitable for the make, model, and age of your vehicle. If you purchase one that isn’t, then it will not fit properly. At best, this will mean that you have wasted your money, at worst it could mean that you cause further damage to your vehicle and potentially put yourself and others at risk of a catastrophic failure.

To ensure you buy the right ball joints, refer to your owner’s manual or the vehicle manufacturer’s website. Here you should be able to find the exact specifications for the part that you need. Also, check whether your vehicle requires a single ball joint on either side or has upper and lower ball joints. If the latter is the case, then bear in mind that upper and lower ball joints differ in their construction.

Design is also an important factor to consider. While the primary parts in each correctly fitting ball joint will be the same, the design of those parts can differ in terms of quality. The main parts within the ball joint are the housing, bearings, ball stud, and washer or spring. When looking at the quality of the parts, considering things like the strength and durability of the metal used in the bearing; how the parts are lubricated; and the construction of the shell.

The materials used to create each of the parts is just as important. Look for hardened metals that offer greater durability and strength. Hardened steel is wear-resistant and offers greater resistance to corrosion.

The position and role of the ball joints on your vehicle make them susceptible to corrosion as well as wear and tear. You can reduce both by choosing ball joints that have high-resistance coatings. This type of coating protects the ball joint from contaminants, which are the main cause of corrosion; polyurethane is a common coating used for this purpose.

Different Types of Ball Joints

Ball joints connect the control arms on your vehicle to the steering knuckles. As the wheels are steered the ball and socket design allows the joint to swivel and the knuckles to pivot and arc so that they can follow the suspension’s vertical motions.

The type and number of ball joints required by a vehicle depends on the type of suspension present in the vehicle. Those with SLA (short-arm suspension) have two upper and two lower ball joints.  Vehicles with strut suspension have two lower ball joints in the front suspension. The exception to this is vehicles equipped with wishbone strut suspension; such vehicles have four ball joints. Front-wheel drive vehicles that have independent rear suspensions differ again, often having rear ball joints as well.

The two main types of ball joints are loaded and unloaded joints. Loaded ball joints support or carry weight such as the lower joints on an SLA front suspension and on rear-wheel drive vehicles. Unloaded ball joints do not carry weight. The upper ball joints on an SLA suspension and on rear-drive vehicles and the lower joints in front-wheel drive vehicles that use MacPherson struts are examples of such ball joints.

Best Ball Joint Brands

Two of the best ball joint brands are Moog and ACDelco. A third brand that should be strongly considered is Detroit Axle. However, it is important to ensure that the brand you are considering carries the right ball joint for your vehicle.

  • Moog

One of the reasons why Moog features as one of the best ball joint brands is its design. Moog ball joints reduce friction and enhance stability by allowing grease to flow to the stud. The design also allows it to flush contaminants that would otherwise cause corrosion and shorten the lifespan of the part. The steel composition of the Moog ball joint also increases its strength and durability. Other benefits of a Moog ball joint include its large housing, which improves fit and its dust boots. Moog products are also value for money and are generally considered to be affordable.

  • ACDelco

One of the benefits of ACDelco ball joints is that the housing is forged as a single piece. This greatly enhances the durability of the ball joint. ACDelco is also well known for testing its parts to extremes to ensure that they are strong and long lasting. The company specifically tests for fatigue and against severe impact. The durability of ACDelco parts is enhanced by the corrosion-resistant polyurethane coating used on the parts. Finally, the ball joints are suitable to use on a wide range of GM and non-GM vehicles, which increases their usability.

  • Detroit Axle

One of the reasons why Detroit Axle should be considered as a top brand is because they provide complete suspension kits that include everything you need to swap out your vehicle’s suspension. This saves you from having to purchase parts individually and running the risk of having incompatible parts. Detroit Axle reviews suggest that the kits are easy to install, fit well, and are generally indistinguishable from the factory-installed parts on compatible vehicles.

Best Ball Joints FAQ:

Q: What are the ball joints and how do they work?

The ball joints in your vehicle directly affect the precision of your steering and allow you to steer and control your vehicle over uneven ground. Ball joints are comprised, of a ball and socket. The ball sits in the socket and creates a connection, while at the same time having freedom of directional movement. Think of the ball and socket joints in the human body, such as the hip and shoulder. Without these types of joints here, your freedom of movement would be severely limited. The same is true of the suspension on your vehicle. In this instance, the ball joints connect the steering knuckles to the control arms on your vehicle and create a pivot point. This enables the vertical movement of your suspension while allowing you to steer left or right as required. The placement of your vehicles ball joints depends on the type of suspension in your vehicle. Generally, they are part of the front suspension. However, some rear-drive cars will have ball joints in the rear suspension.  The inclusion of ball joints in the suspension enables vehicles to travel safely over a wide range of different and uneven surfaces, including dealing with rocks, bumps, and potholes. The vertical movement enables the wheels to stay in contact with the road surface as it changes. Ball joints also allow vehicles to carry heavier loads.

Q: How often should I replace my ball joints?

It is generally accepted that ball joints need to be replaced after between 70,000 and 150,000 miles of driving. However, road conditions and the general condition of your vehicle will affect how often you need to replace the ball joints in your suspension. Changes in your steering or unusual noises from your suspension should be investigated as soon as they are noticed as these are key signs of wear in your ball joints.

Q: How do I know if ball joints are worn?

  Signs that your ball joints are worn and need replacing include:
