How To Tell If A Strut Is Bad

Table of Contents

The Warning Signs Of Worn Shocks And Struts Instability at highway speeds. Vehicle “tips” to one side in turns. The front end dives more than expected during hard braking. Rear-end squat during acceleration. Tires bouncing excessively. Unusual tire wear. Leaking fluid on the exterior of shocks or struts.

What does a bad strut sound like?

Bad strut sounds are usually described as a hollow clunking or banging type of sound. You’ll typically hear the noise when the vehicle is traveling over irregularities in the road. Most front strut assemblies also have a bearing at the top.

Can you drive on bad struts?

Is It Dangerous to Drive with Bad Struts? Yes, it’s dangerous to drive with bad shocks or struts. Fortunately, many signs indicate your car’s shocks and struts are malfunctioning, such as: Your car feels unstable, even if you are driving on a flat surface.

How do I know if my front struts are bad?

How do I know if I need new struts?

When struts are worn or damaged, the vehicle will often compensate in other ways. You may notice a “nose-diving” sensation as well as instability while braking. If you feel a lurch forward while braking, you’ll need to have your struts and shocks checked out by a mechanic.

What happens if front struts fail?

When they wear out, the suspension will sag, causing the front tires to absorb more heat on the inner or outer portion of the tire. Engine: if the struts fail completely, the reduced drag produced by misaligned suspension can also put more stress on internal engine components and lead to significant damage.

What happens if you don’t replace struts?

Safety: Worn struts result in longer stopping times and/or distances as the vehicle weight can shift (sometimes unexpectedly) during braking. Wear on other parts: Driving with bad struts accelerates the wear on tires, as well as other components of the suspension system, such as the springs.

How much do new struts cost?

To replace a pair of struts, the total cost on average is between $400 and $1000, including wheel alignment. An individual strut assembly costs approximately $150 to $350, while the labor cost is $100 to $300 for a pair.

Are struts worth replacing?

Struts don’t need to be replaced unless your vehicle is bouncing like it’s on a pogo stick or bottoms out in potholes and over railroad tracks — or unless a mechanic finds that they’re leaking fluid or have been damaged. The struts limit the resulting bouncing caused by the springs compressing and releasing.

How often should you replace your front struts?

Generally, shocks and struts wear out every 50,000-100,000 miles. If you’re a more aggressive driver and/or frequently drive on rough roads, they will wear out faster. Shocks and struts don’t go out all at once; they deteriorate slowly over time.

How long should struts last?

On average shocks and struts can last 5-10 years or 50,000-100,000 miles under ideal driving conditions. Many factors can affect the lifespan of these components to include: manufacturer, bad roads, heavy loads, towing, hard braking and aggressive driving.

What do new struts feel like?

Bumpy ride You’ll feel bumps more, so the ride will feel rough. If you feel like you’re about to lose control of your car when you drive over a bump or pothole, it’s likely your shocks or struts need to be checked out.

Is a strut and a shock the same thing?

However, shocks and struts are two distinct parts with different functions. While both can help with your vehicle’s ride and handling, these parts work in different ways. Shocks are individual components of the suspension system while struts are a major structural component of the chassis and suspension system.

Can you replace struts yourself?

Strut Replacement Replacing struts used to be a dangerous job for a DIYer. But these days you can buy a complete strut assembly that eliminates the strut/spring/mount disassembly process. These assemblies allow you to replace both of your front struts yourself in less than two hours.

How much does it cost to replace a strut top?

Replacing both struts together with strut mounts will cost from $650 to $900 in an average car. In some cars, the wheel alignment must be performed after replacing front strut mounts or struts.

Can you fix a blown shock?

Generally, you would have two options to fix the problem of worn shocks: repair the broken part(s) or do a shock absorber reconditioning. Contrary to what many people think, shock absorbers can be fixed. It is usually cheaper than having to buy new ones, especially when you have to replace four of them at a go.

Do worn struts cause tire wear?

Bad shocks or struts will cause the wear to be uneven. For instance, you may have a flat patch of a tire on the left side and then have wear in the center of the tire in another place. Bad shocks or struts can even ruin brand new tires and cause them to need replacement prematurely.

Does my car have shocks or struts?

Rather than looking for coil springs on these parts to tell them apart, look at the bottom portion of the absorber. If it is held in place by only one bolt, you’ll know you have shocks and not struts. You’ll also know you have a shock if your vehicle has an upper control arm.

Is it OK to replace only one strut?

It’s not necessary, but it’s usually recommended to replace them in pairs, for example, both front struts or both rear shocks. However, if your car is not very old, replacing only one strut or shock absorber may be enough, since the opposite side is not worn out yet.

Do you need a wheel alignment after changing struts?

Strut suspension usually has the shock absorber and the spring in one unit, with the top of the strut mounted very high in the car body and the bottom of the strut attached to the lower control arm. This lowers the vehicle center of gravity, which is a good thing. Replacing those struts requires no alignment.
