Signs Of A Worn Suspension: Shocks And Struts

What are Shocks? What are Struts? Which Does Your Car or Truck Use?

As a car owner, you are well aware that your vehicle needs regular care like tire replacements and oil changes. But, how often do you think about your cars suspension?

Because drivers often think that suspension is only about a smooth ride, this part of the car can be overlooked a lot when it comes to repairs. Your suspension is made up of many parts and can affect the ability to steer and turn the car too.

Your cars suspension basically connects the body of the vehicle to the wheels. Its what gives the driver the ability to steer and move the car. The suspension is made of many things tires, tire air, springs, links, and struts/shock absorbers.

Thats right, struts and shock absorbers are different components. They can be found in separate cars and are not interchangeable.

For example. If you have a car that is built with struts, you cannot replace those broken or worn parts with shock absorbers. So, whats the difference?

Do All Vehicles Have Struts

Not all cars and trucks have struts many suspension designs use separate springs and shock absorbers, with the shocks supporting no weight. Also, some cars use struts only on one pair of wheels, usually the fronts, while the other pair employs a different design using separate springs and shocks. When a car has struts on the front wheels only they are usually MacPherson struts, which are struts that are also considered part of the steering system because the wheels pivot around them.

Why do some vehicles use struts while others have separate springs and shocks? The specifics are complicated but for the most part it comes down to a trade-off between simplicity and initial cost and handling and performance . But there are exceptions to these patterns for example, most sports cars employ whats called a double wishbone suspension, which uses shock absorbers rather than struts, but the Porsche 911, which is arguably the quintessential sports car, uses struts.

Your Cars Tires May Wear Down Faster Than Expected

As your cars shocks and struts deteriorate, you may notice your tires tread start to cup or show other signs of wear and tear. Worn-down tires can make it difficult to safely steer your car, which may result in an accident. Furthermore, defective shocks and struts that contribute to worn-down tires may force you to replace your tires sooner than expected.

How To Buy Replacement Shocks And Struts

Make sure you buy quality, brand-name shocks or struts, recommends Trotta. And remember that youve got choices. Some may be a little stiffer for better cornering, while others may offer better ride comfort. Discuss your preferences with your auto professional before deciding.

Its also important to ask about replacing all of the worn parts connected to the struts. Dont be penny wise and dollar foolish, cautions Reina. He recommends replacing other worn items associated with the struts, like bearing mounts, rubber bump stops and shock boots.

Whatever you do, dont neglect your shocks or struts. Just like with that comfortable pair of shoes, you wont fully appreciate the difference they make until you get fitted for new ones and hit the pavement.

What Do Struts Do On A Car

A strut performs two key roles. First, it acts as a damper that controls a car’s spring and suspension movement. By doing this, a strut can give a vehicle a smoother, more comfortable ride. Second, each strut supports the vehicle’s suspension. In this function, each strut supports a car’s springs and can help keep the tires in an aligned position.

How To Test Struts

Because the struts are different in terms of their location and function, the test for shock absorbers will not work for them.

The only way to test the struts is by performing a road test and paying attention to any signs of wear such as shakes, rattles, or nosedives.

Getting Your Shocks & Struts Replaced

How to Replace Struts in your Car or Truck

The best way to know when to replace your shocks and struts is to have a qualified technician inspect your suspension anytime you notice the above signs, get an alignment or install new tires. At the very least, get your car suspension checked once a year.

Shocks and struts should always be replaced in pairs , and its even better to replace the shocks/struts on all four wheels at one time. This helps maintain reliable handling and a consistent response on both sides of the vehicle.

After you get any suspension work done, we always recommend getting an alignment too. Any changes in your suspension may also change the vehicles wheel alignment. And when it comes to wheel alignment, even minor tweaks can have costly consequences down the road .

How To Fix The Problem

before spending time and money to replace the struts, you should have a mechanic perform a thorough diagnosis. other suspension components such as bushings and mounts can mimic strut problems.

worn or damaged struts should be replaced in pairs front or rear. the struts can usually be exchanged as an entire assembly with the springs , or they can be serviced separately.

we recommend replacing the upper strut bearings and bushings along with the struts, and getting a wheel alignment once the new parts are installed.

this is a job best left to professionals, since the strut assembly contains dangerous, high-tension springs. the mechanic will remove the old strut, possibly along with brake lines or other suspension parts that are in the way. he or she may remove the old strut from the spring and add the new strut to the spring. once the new struts are in place, everything will be reassembled.

Signs That You Need To Replace Shocks & Struts

Generally, shocks and struts wear out every 50,000-100,000 miles. If youre a more aggressive driver and/or frequently drive on rough roads, they will wear out faster.

Shocks and struts dont go out all at once they deteriorate slowly over time. Because of this, you may not notice that your suspension is going bad until things go from bad to worse! Watch out for these 4 main signs that you need to replace the shocks and/or struts.

1. Bumpy, rough ride

When you hit a bump in the road, do you feel like you could lose control of the vehicle? Does your vehicle bounce more than once or twice? A rough, bumpy ride is one of the easiest symptoms to notice.

2. Leaking fluid

Leaked fluid on the exterior of the shocks/struts is a sign that something is wrong. If the shock absorbers do not have enough hydraulic fluid, they wont be able to absorb impacts as you drive.

If youre not sure whether the liquid on your suspension is coming from the shocks or is an old fluid leak from somewhere else, wipe it off and then check it again after youve driven at least a few miles.

3. Uneven treadwear

Cuppingscalloped, wavy dips on the tire treadis a tell-tale sign of worn shocks and struts. It is caused by the tires not being held firmly to the road as you drive. Cupping shortens the usable life of your tires and diminishes handling and stopping power.

4. Instability when braking or turning

As a result, going over a bump or pothole can potentially cause you to lose control, putting you and your passengers at risk, as well as risking an accident with other vehicles on the road. For this reason, its crucial to keep your shocks or struts in proper working order at all times.

What Problems Could Occur If I Drive On Bad Shocks And Struts

Your shocks and struts are an intricate part of your vehicle, and interact with your cars suspensions, steering and alignment systems. Bad shocks and struts can lead to excessive tire wear and excessive suspension wear, costing you extra money on auto repairs down the road. They also directly affect how you are able to handle and control your vehicle on the road, a vital element in keeping you and your family driving safely.

What Do My Cars Shocks And Struts Do

Shocks and struts are needed to maintain your vehicles balance and stability while driving. In other words, they are what are responsible for keeping your car flat on the pavement! This helps you keep control of your vehicle so it is not bouncing off the ground due to bad weather, rough terrain or simple potholes.

The spring in your cars suspension works to absorb the impact your car gets from hitting a bump or pothole in the road. Your struts provide support for your suspension springs, and your shocks work to dampen the subsequent spring movement so that your car doesnt continue to bounce.

What Are Struts On A Car

Different types of cars have different types of suspensions. Most car owners have heard the term strut, but may not be clear as to what exactly the struts on a vehicle are or what they do.

Most straightforwardly defined, the struts are a structural component of most modern independent suspension systems and serve as a connection point between the wheel and the vehicle body. They are mounted at the top of the chassis at the front-end of most front-wheel-drive vehicles. However, struts are not limited to front-wheel-drive configurations. The primary purpose of the struts is to support the weight of the vehicle while also absorbing surface impacts and ensuring a smooth ride.

A strut assembly consists of two primary elements: the coil spring, which supports the height, weight and stability of the vehicle and the shock absorber, which swallows bumps and dampens vibrations caused by irregularities on the roadway.

Shocks and struts are terms often used together or interchangeably, but that can create confusion. There are major differences between the two components. Shocks, by themselves, have one primary function to absorb bumps at each wheel but they are not essential in the operation of a car or truck. Struts, on the other hand, have multiple functions and are essential for vehicle operation. Struts allow control and maneuverability of the vehicle.

When to Replace Shocks and Struts On Your Car

What else does a vehicle owner need to know about struts? Not too much. Whether your car has struts or shock absorbers youll want to have them inspected periodically for leaks or other damage. One difference is that when they do wear out, struts are more expensive to replace, but theres nothing a driver can do about that. Regardless of what suspension system your car has, be sure to have it inspected regularly every oil change or alignment, or every 5,000 miles or so is fine.

The Vehicle Exhibits Signs Of Body Roll

Similar to how a vehicle can dip and squat during braking and acceleration events, a cars stability may also be compromised during cornering. If the shocks are starting to go bad, the body will feel like it is leaning into the turn even on slight turns. Again, this can be a safety issue that requires immediate action since it can impact braking and steering effectiveness.

Over 50,000 miles, the dampening capabilities of a shock or strut will degrade to the point where it can impact ride and handling, but the driver may not notice since the loss of functionality happens gradually. While your customer may have become accustomed to body lean as a normal part of their driving experience, your fresh perspective can reveal just how bad their shocks and struts have become. This is why a test drive is critical to the inspection process.

When To Replace Shocks And Struts On Cars

Its recommended that you replace each strut and shock absorber on your car every 50,000-100-000 miles.

There are some indicators that will let you know if these parts need replacement. If your car’s ride quality has suddenly become unusually bumpy or if you have poor steering response, it could indicate a strut or shock absorber issue. Other signs that indicate that there’s a strut or shock absorber problem include unstable braking and unusual wear patterns on the car’s tires. The Federal Trade Commission advises that worn shock absorbers can cause poor cornering.
