Ball joints are a vital component of your suspension system. They allow you to turn and steer your vehicle smoothly.

If you start to experience issues steering or while you’re turning, you may have a bad ball joint.

While it sounds like an issue that can be overlooked, it’s not.

If not addressed, this easy and inexpensive repair can lead to more extensive repairs and dangerous driving conditions.

If you think you have a bad ball joint, you’re in luck.

In this post, I will go over the common symptoms of a bad ball joint to address it as soon as possible.

Let’s get started.

1. Rattling or Clunking noises

If you start hearing faint noises coming from near your tires, this is a sign of bad ball joints.

This noise is caused when the suspension goes up and down. The movement will cause the ball joint to rattle, which causes the noises.

One great way to determine if your ball joints are making this noise is to drive over a speed bump.

As your car goes over the sped bump, pay attention to determining is any clunking or metal-on-metal rubbing.

This is a clear sign that you need to inspect your ball joints further.

2. Excessive vibration

Another common sign of a bad ball joint is excessive vibration coming from the front of the car. You will typically feel these vibrations coming stronger from the side with damaged or bad ball joints.

A bad ball joint will vibrate as you drive. These vibrations will reverberate through the chassis, axel, and even the steering wheel.

These vibrations are not always felt when the car is idle. But they become easily noticeable when you begin to drive, especially when the suspension is working, such as going over speed bumps, hills, or turning.

3. Suspension Damage

Another common sign of a bad ball joint is suspension damage. This typically happens after extended driving with a bad ball joint.

Ball joints are crucial parts of the suspension system. Ball joints help manage lots of the moment and shock on your suspension.

When they go bad, this moment and stress get directed to another part of your suspension.

Over time this additional stress can cause other parts of your suspension to get damaged, such as your bushings.

The bushings are made of plastic and not meant to withstand the additional stress of driving on a bad ball joint.

4. Uneven Tire Wear

When your ball joints begin to deteriorate, you will also begin to notice additional wear on your tire.

This typically occurs because, without a proper working ball joint, your tires experience additional stress causing them to wear more than they usually would. This stress comes from your suspension’s inability to align while you drive.

In most cases, you can see a significant difference in the wear on your front tires depending on which ball joint is bad.

You might also notice that one single tire may have uneven wear on it.

For example, the inside or outside of the tire may have more wear than the center.

This is typically due to the suspension’s inability to balance the vehicle as you drive.

While your suspension works to balance out your vehicle, the bad ball joint will leave the car unbalanced.

5. Drifting Steering wheel

Bad ball joints can also cause your steering wheel to shift to the right or the left on its own.

This is typically thought to be an alignment problem, but this is not always the case.

Even with proper alignment, bad ball joints can cause the steering wheel to drive.

Ball joints play a crucial role in your vehicle’s suspension and chassis. When your ball joints are damaged, they can lock up or become rigid, not allowing for a smooth ride.

This is the main reason that the steering wheel begins to wander.

Another sign of a bad ball joint is when it starts drifting from left to right on its own.

You shouldn’t ignore this issue since once it escalates, accidents may happen.

What Causes Bad Ball Joints?

1. Normal Wear

Ball joints are the primary reason you can steer and turn your vehicle smoothly. This means that they experience lots of movement and friction.

Like any other part inside your car, it experiences normal wear and tear, which can cause a bad ball joint.

They are expected to last between 75,000 and 150,000 miles. But harsh conditions and erratic driving patterns can reduce that and add additional wear on your ball joints.

2. Dirt and Grime Inside the Ball Joint

Ball joints have a protective casing that is intended to protect your ball joints from dirt and grime.

But, if this protective casing is damaged or defective, this can eventually lead to a bad ball joint.

While your ball joint will operate perfectly fine without a protective casing, over time, the additional dirt and grime that gets inside your ball joint can cause severe damage.

First, the additional dirt can increase the friction and wear on your ball joint.

Second, the dirt and grime can cause the socket to become rough and eventually lock up.

This will prevent movement in your ball joint, and it will eventually break.

3. Over-greasing

Too much of something isn’t good. This also applies to greasing since it may cause the rubber boot to break. Once it does, dirt, water, and other debris would be able to enter.

Of course, this only applies to the serviceable units.

4. Under-greasing

In contrast, if your ball joint doesn’t have enough grease, friction would increase. I hope that rhyme would make you remember it better.

Of course, with increased friction comes a bigger chance of the ball joint wearing out faster.

Again, this also applies only to the serviceable units.

5. Failure to clean the grease fitting

Not cleaning or maintaining the grease fitting can lead to a bad ball joint. 

The contaminants and debris can enter the ball joint and cause serious damage. 

These contaminants can lock-up the ball joint, absorb the grease, increase friction and cause unnecessary wear on your ball joint. 

The more contaminants that enter the grease fitting the more damage they will cause. 

6. Harsh Driving Conditions

Rought driving conditions can also lead to a bad ball joint.

Not all ball joints are created equal. Some ball joints are not built for specific movements or extreme conditions.

By repeatedly exposing your ball joints to these extreme conditions it can reduce the lifespan and increase wear.

These harsh conditions can eventually deteriorate or destroy your ball joint.

It’s vital that you purchase ball joints that match the driving you will be doing.

Good Ball Joint vs Bad Ball Joint: What Does A Bad Ball Joint Look Like?

A bad ball joint is not always easy to tell from appearance. They can also take on many different forms. 

In some cases it’s easy to identify a bad ball joint while with others it’s difficult. 

Some key signs your ball joint is bad are: 

  • Bent ball joint
  • Damaged ball joint boot 
  • Cracked or damaged ball joint housing body 

Ball Joint Anatomy

ball joint anatomy
  • StudThis spherical stud is the rounded part of the joint that withstands the most pressure. It rotates in a lubricated space in the housing. 
  • BearingMade from either nylon or metal, it can reduce the ball joint’s friction.
  • End cover or backing plate: Both wear- and impact-resistant, these hoods in the ball end of the joint.
  • HousingServing as the metal ball stud’s protection, it holds grease and prevents dirt from going inside.
  • BootUsually, polyurethane acts as a shield to protect the ball joint from water and dirt. 
  • Grease nippleIt is also known as a grease fitting; it provides the opening to add grease to the ball joint. The grease fitting also acts as a wear indicator. If you see a part of it on top, the joint is still intact. 

Frequently Asked Questions (FAQ)
