4 Symptoms of a Bad Lower Ball Joint and Replacement Cost

The lower ball joint is what attaches the steering knuckle and control arm together. There are two pieces which make up the lower ball joint; a socket and ball. These pieces are inside of a rubber boot that is filled with lubricant.

Basically, the lower ball joint allows the wheels and tires to be connected to the vehicle and its steering assembly. This is what enables you to make right turns or left turns with the steering wheel. It also enables the vehicle’s suspension system to travel over bumpy terrain without any setbacks.

So what happens if there’s a problem? If a lower ball joint is bad, there are a few signs you should look out for.

Top 4 Bad Lower Ball Joint Symptoms

The lower ball joint would probably seem like an insignificant part if looked at by itself because it is so small. However, it is a part that allows other parts of the suspension system to function properly.

If the lower ball joint were to get worn out or break, then you would have a number of negative symptoms come up. Below are four of the most common signs that indicate a lower ball joint goes bad.

1) Vibrations

When you have a bad lower ball joint, you will be able to feel vibrations in the steering wheel or from the left or right side of the vehicle. These vibrations are coming from the suspension system.

If the lower ball joint is worn out, it will become loose which is why the vibrations occur. A loose ball joint will continue to vibrate as you drive your vehicle.

Any kind of shaking like this should be a clear sign that something is wrong and that you need to get your lower ball joint checked.

2) Clunking Sounds

A symptom of a faulty lower ball joint that people experience on a regular basis is clunking sounds. These sounds will come from the suspension of the vehicle.

When there is a worn ball joint present that has loosened, it will start to rattle around and knock into the socket. This creates those clunking sounds that you’re hearing. You will hear these sounds even more when you’re driving on rough terrain or roads, especially a bumpy surface.

If you don’t get the ball joint replaced soon, it will get louder and eventually break off completely.

3) Tire Wear

One sign of a lower ball joint that has failed that people don’t often consider is uneven tire wear. If any of the interior or exterior edges of your tires have excessive or unusual amounts of wear, this is also a sign that your lower ball joint could be bad.

This symptom may not be an immediate problem to fix, but you shouldn’t let it go for too long or it will become a big problem. It’s good to check your tire condition on a regular basis but if you fail to do that, you’ll hear about the wear the next time you have your tires rotated.

4) Wandering Steering Wheel

Do you notice that your steering wheel is pulling too much toward either the left or right? If so, this is likely due to a bad alignment or a faulty lower ball joint because the wheels will become misaligned and then you’ll have to work harder to keep the steering wheel straight.

Don’t let your steering wheel continue to wander like this for too long because the problem will only get worse in time. Get the ball joint replaced right away if it ends up being the culprit.
