Car bushings can be found on several components of your vehicle and often look like large, rubbery washers. They work to absorb vibrations, bumps, and road noise. This protects the part they’re situated on from excess wear.

Unless you spend a lot of time in an automotive garage, car bushings aren’t likely something you know much about. But these all-important car parts protect other vehicle components from the excess vibrations and friction of driving. They also protect your sanity by reducing movement and noise in the cabin to give you a smoother ride all around.

It’s important to swap out any worn-out and ineffective car bushings—but bushings on a car don’t have a regular replacement interval, so you’ll need to be able to watch for the right signs. Here to break down what car bushings are is

What are car bushings?

Bushings on a car are components that sit on the vehicle suspension system, steering joints, engine and transmission mounts, and more.

They’re typically made of rubber or polyurethane surrounded by metal sleeves, and look like large washers. They may have a different design depending on their function and the part they’re situated on.

Rubber bushings are also referred to as flexible or anti-vibration mountings and work to absorb vibrations, noise, and excess movement from the road. Think of these parts as the cartilage in your body’s joints that prevent your bones from wearing on one another.

What are the symptoms of worn bushings?

Worn bushings (while perhaps not as dire as worn knee or elbow cartilage) are important to replace. It’s natural for bushings to wear over time, especially ones situated in places where they’re exposed to things like motor oil, road salt, lubricants, or other potentially deteriorating chemicals.

They’re also vulnerable to heat damage and the stress of daily movement and weight.

Now, there isn’t an exact timeframe that you can reference to know when your car’s rubber bushings are due for replacing, but there are symptoms of bushings wear that you can keep your senses out for:

Increased vehicle movement, shimmying, or swaying while driving

Rattling or clunking noises when turning or braking

A pull to one side of the road while speeding up or slowing down

A loose steering wheel or loose handling

Keep in mind, though, that these symptoms are more specific to the front suspension and engine and transmission mounts.

The vehicle’s rear suspension bushings aren’t involved with or affected by the steering system, so wear on these parts will be less noticeable.

What exactly happens when your suspension bushings are worn out?

Worn suspension bushings allow the metal parts on either side of a joint to come in contact more often, leaving them susceptible to friction damage and putting more pressure and stress on the joint itself.

Left this way, the suspension component that the bushing is placed on could snap, and you’d be stuck with some serious damage to your vehicle. You’re also likely to see accelerated tire wear.

A little less worrisome (but still an issue you’d likely want to fix) is the squeaking noise that can come about from worn-out, dried-out suspension bushings.

Though it depends on the design of the bushing or bushings in question, you may be left having to replace the component to remedy the squeak.

How do you replace bushings?

If you suspect that your car bushings are worn out and need replacing, you may want to bring your vehicle to a repair shop to have a certified mechanic conduct a bushing inspection. This will identify where exactly the worn bushing is and what your repair options are.

Many bushing designs can be quite difficult to remove. For instance, if we’re talking about control arm bushings, you’d have to replace the entire control arm rather than just the bushings. For issues like that, it’ll be best to have the repair done by a mechanic with the appropriate expertise and tools needed.

However, if you’re car-repair savvy you may wish to replace the worn car bushings yourself. If that’s the case, you’ll need to pay extra attention to two factors of the replacement.

When replacing the bushings, note the correct depth and orientation of the original one so you can copy them with the new one. If the bushing is placed too deep, too shallow, or with incorrect orientation, the overall performance of the bushing will be reduced.

You’ll also need to ensure all four wheels are on level ground before tightening the fasteners of the control arm bushings, shock and strut bushings, and sway bar bushings. This will help prevent misalignment.

How often should you replace your suspension bushings?

As we mentioned earlier, there isn’t a hard and fast timeline for replacing your suspension bushings. Instead, you’ll need to pay attention to any symptoms of worn bushings that may come up.

You should also take your driving environment and habits into account. Rubber bushings will wear faster if your driving conditions are on the harsher side. Factors like extreme heat, excess dust and dirt, road salt, motor oil, slamming on your accelerator or brake, and rough roads can deteriorate suspension bushings quicker.

If you notice that your car is swaying more than usual or pulling to one side, your steering wheel feels looser, or you’re hearing unfamiliar clunking or rattling noises, it may be time to replace your car bushings.

How much does it cost to replace car bushings?

We know car repairs can add up quickly, and heading to the mechanic without a clue of what your wallet will be put through can be scary, so let’s go over some pricing.

It’s common for car bushing replacements to cost between $145 and $690 depending on the placement and function of the bad bushing. Naturally, labor time and costs will increase for the more difficult repairs and replacements, and your car’s make and model will affect the price as well.

Replacing the worn-out parts with new bushings can get expensive, but they are important components of a healthy vehicle and smooth ride.

How important are car bushings?

While maybe not the most important car part, bushings are crucial for keeping your car’s suspension in alignment, reducing metal contact friction, minimizing road noise and excess vibrations, and controlling joint movements.

What are the different types of bushings?

Bushings can be found on the control arm, shock absorber, stabilizer bars, tie rods, strut mounts, ball joints, suspension systems, steering system, and engine and transmission mounts.

Can you drive with broken bushings?

A broken bushing can cause uncontrollable vibration and rattling noises that are at best distracting and at worst signs of another car part on the brink of snapping.

It may not cause irreparable damage right away, but it certainly isn’t something you want to sit on for a while.
