Many drivers are unaware of how essential shock absorbers and struts are to vehicle safety. Like all components of the powertrain, shock absorbers and struts can wear out over time. You need to know how long shock absorbers last and when to replace shock absorbers and struts to detect faulty ones and protect your car’s safety.

What are shock absorbers and struts?

Many people use the terms interchangeably, but shock absorbers and struts are two different parts of a car’s powertrain. They are part of the suspension system that dampens shocks and vibrations when the car is on the road.

The suspension can be of several types, but the most common consists of a combination of shock absorbers and struts. On modern vehicles, shock absorbers remain on the rear wheels while struts are found at the front. They mitigate the vehicle’s lateral movements caused by bumpy roads.

Shock absorber and strut assemblies work continuously, whether the car is moving or not. For this reason, they deteriorate more quickly. But how long do shock absorbers last and what is the lifespan of struts?

How long do shock absorbers last?

The lifespan of shock absorbers, as well as struts, is at least 4 to 5 years. However, this depends on road conditions. The lifespan can extend up to 10 years if you drive the car mainly on smooth pavement. Similarly, it can be less than 5 years if you primarily drive on uneven roads filled with cracks and potholes.

Some experts use mileage to track the condition of shock absorbers and struts. The general rule is that shock absorbers last at least 50,000 miles before needing replacement. But again, it’s difficult to predict an exact figure when it comes to the lifespan of struts or the lifespan of shock absorbers. They might not last as long if the roads the car was driven on were not smooth and flat.

So, how long do shock absorbers last? The regular numbers are either 5 years or 50,000 miles. But it can be more or less depending on the condition of the roads. The same rule applies to strut assemblies.

Symptoms of bad shock absorbers and struts

Once shock absorbers and struts start to wear out, they bottom out quite quickly. The seals around their joints begin to wear out, and the fluid or gas inside leaks.

Watch out for these signs as they warn you of shock absorber and strut failure:

• Moisture on the top of these components or drips on the side in the case of a fluid-based unit.
• In turn, it feels like the rear of the car is a bit “loose.” Furthermore, the rear seems more bouncy than usual.
• Knocking noise coming from the rear suspension.
• Driving on rough and uneven roads becomes tiresome due to excessive shaking and jolting.
• The car does not sit level with the ground.
• Excessive bouncing: If you notice your vehicle bouncing excessively after hitting bumps or dips in the road, it could be a sign of worn shock absorbers or struts. The bounce may be more pronounced, and the vehicle may take longer to regain stability.
• Poor handling and stability: Worn shock absorbers and struts can lead to decreased vehicle stability, causing excessive swaying or leaning of the car during turns or maneuvers. You might experience a loss of control or a floating sensation while driving.
• Fluid leaks: If you observe oil or fluid leaking from the outside of the shock absorbers or struts, it indicates damage or failure. The presence of fluid is a clear sign that the internal seals have deteriorated and the component needs to be replaced.

Regular maintenance and inspections by a qualified mechanic are essential to ensure the proper functioning of your shock absorbers. They can assess the condition of the shock absorbers and determine if replacement is necessary based on factors such as wear, leaks, or reduced performance. Remember that worn shock absorbers can negatively impact handling, braking, and the overall safety of your vehicle. Therefore, it is important to address any issues promptly.

Do you know how to bleed ABS brakes? Bleeding is necessary when replacing an ABS modulator or other hydraulic components. It may not be necessary during a wheel-level hydraulic repair, but you must be careful not to let air into the system. You need to bleed brake systems when air bubbles enter the system during a repair or replacement task.

An anti-lock braking system (ABS) tolerates air bubbles and contaminated fluids less than a non-ABS system. An ABS hydraulic pump uses thousands of psi to push brake fluid through tiny valves. Contaminated fluid can easily damage the valves and pump, so you should never delay when the system needs to be bled. Although bleeding ABS brakes is difficult because the high pressure in the pump whips the air bubbles and brake fluid into a foamy substance.

The Need for ABS Brake System Bleeding

We already mentioned that the system needs to be bled due to air bubbles present in the system. But how do these air pockets form inside the system?

Well, whenever the brake lines are opened to repair or change certain parts such as wheel cylinders, calipers, or ABS units, air enters the system.

When there are air pockets inside the lines, the brake pedal feels spongy and the whole system feels unbalanced. For this reason, brake bleeding is mandatory for any brake work. Skipping it would lead to various braking problems after some time, as without bleeding, you not only let the air pockets remain but also push contaminants through the system.

Flushing the brake fluid every two to three years is part of the regular maintenance schedule. This will keep the system free of contaminated fluid and air bubbles.

How to Bleed ABS Brakes: A Technique for All Types of Units

Bleeding involves removing air pockets and replacing the old fluid. The old fluid must be changed because polluted fluid absorbs moisture from the air and lowers its boiling point. Such degradation affects braking performance.

Things You Will Need

• A few 8-ounce cans of brake fluid
• Plastic tube
• Car jack and jack stands
• A turkey baster
• A hex key
• Cloths or microfiber towels
• Spacer
• A small bottle
• Gloves and safety glasses

The ABS Brake Bleeding Procedure

Before removing bolts and loosening nuts, you will need to prepare for bleeding the brakes. This includes lifting the vehicles and removing all four wheels. You can also work by keeping the wheels in place, but lifting the vehicle high enough to be able to use a wrench on the bleed valves.

Loosen the Bleed Valves

After preparing the vehicle, your first task is to loosen the bleed valve bolts. Use a hex key for the job. If the bolt threads seem rusty, spray some penetrating oil the day before. This will make the job easier as you can break the corrosion with a few light taps with a hammer.

Be careful when doing this as these small hollow bolts can break if you apply excessive force. If this happens, you will need to replace the wheel cylinders or brake calipers (depending on the vehicle model), meaning a loss of time and additional money.

Carefully loosen the bolts so they don’t break. Leave them closed without removing them completely. Let’s move on to the next step: how to bleed ABS brakes.

Remove the Old Fluid

Use the turkey baster to remove the old fluid and deposits from the master cylinder reservoir. Use a lint-free cloth to remove sludge from the reservoir. Be extremely careful when handling brake fluid as it is corrosive. An accidental spill on a painted surface will immediately dissolve the paint. You should also wear gloves so they don’t touch the skin.

Bleed the ABS System

Take a piece of plastic tube (any type of cheap tube will do) and push one end onto the brake bleed bolt. The other end will go into a small bottle filled with an inch or two of fresh brake fluid. This little trick will prevent air from re-entering the caliper or brake cylinder.

By releasing the line pressure, the pedal will move from its position. To prevent this, place a spacer under the pedal. Then, fill the master cylinder reservoir with new, clean fluid and close its opening by replacing the cap. Otherwise, every time you release the pedal, fluid will spurt out through the reservoir opening.

You will need an assistant during this bleeding process. At this point, ask them to press the brake pedal with a force you would apply to stop the vehicle at a traffic light. Tell them to maintain pressure while you turn the bleed bolt a quarter turn.

This would force some contaminated fluid out through the end of the tube going into the bottle. Close the bleeder when the flow stops completely. Then, ask the assistant to release pressure on the pedal.

This is how to bleed ABS brakes. However, you are not finished yet. Repeat this process until clean fluid comes out of the bleeder. After that, tighten the bleed bolt and move to the next wheel to repeat this same procedure.

Throughout this entire process, keep filling the reservoir with fresh fluid. Never let the fluid level drop below half of the reservoir. Otherwise, air could enter the master cylinder.

Furthermore, you must not skip any of the bleeding steps, as this could draw air into the caliper.

Bleeding with a Scan Tool

Many ABS modulators are not equipped with bleeders. In this case, use a scan tool to operate the pump and valves. How to bleed ABS brakes with a scan tool?

The scan tool is mainly needed to activate the pump and operate the valves to bleed those areas. For example, the Ford version of the EBC 310 requires an NGS scan tool for bleeding. This tool helps operate the dump valves and activate the pump so that it becomes possible to bleed those areas.

If you want to keep your car running smoothly on the road, maintaining proper antifreeze levels is essential. Without antifreeze, having a vehicle would be pointless. As the saying goes, “Small things come in big packages.” The same applies to coolant, which may seem insignificant but can prevent your car from functioning. Keep reading to learn what happens when your car lacks coolant.

What Happens When Your Car Lacks Coolant? The 3 Common Effects

Coolant, or what you might call antifreeze, is a fluid that regulates the engine’s temperature. The role of antifreeze is crucial, and its absence could lead to disasters. Sometimes, you might tend to ignore the low coolant warning light and overlook the consequences. What are they? Let’s explore this in detail for your better understanding.

1. Engine Shutdown

Coolant is present to cool down the very hot components of the engine. Without coolant, the engine parts would heat up but never cool down. This, in turn, would cause the engine to fail and deteriorate the corresponding parts. When the engine fails, the heart of the car breaks down; thus, your car loses its essence of existence.

Today, with the advent of new technologies and modern cars, things have changed for the better. As soon as the coolant level drops, the engine automatically stops. This is a sign indicating the need to top up the coolant. Simply put, you won’t be able to drive further until you provide the right dose of coolant to the system. This is the worst thing that happens when your car lacks coolant.

2. Car Heater Malfunction

The car heater uses the residual heat that the coolant absorbs from the engine. It’s clear that without coolant, the heater won’t receive the dose of heat it needs to function. Under such circumstances, the heater wouldn’t blow hot air at all, or it might blow hot air continuously.

This would be an extreme situation that you wouldn’t be able to handle. Driving in winter would be a task you couldn’t fully enjoy. Even if you’re wondering what’s wrong, checking the coolant levels would prove useful here. You can also refer to maintenance tips to detect symptoms of low coolant levels.

3. Poor Fuel Economy

The benefit of an engine running at the right temperature is reflected in its fuel economy. This is a crucial factor every car owner must consider as fuel prices rise. If you witness a drop in the MPG reading, it would be appropriate to check the coolant levels.

When the coolant level is low, the engine doesn’t lose its “overheating” state, leading to inefficient fuel combustion. Once this happens, the emissions from the exhaust would also increase exponentially. This would further deteriorate your carbon footprint, a key parameter for meeting environmental needs.

According to automotive technical experts, coolant operates in a closed circulation system, making its loss difficult. Normally, during the first 2 to 3 years of use, a small amount of coolant may be lost. If the car owner notices rapid coolant loss, it’s advisable to have the vehicle inspected and repaired.

Coolant leaks and losses can occur due to damaged hoses and perforations. However, detecting coolant leaks can be challenging for car owners, as these areas are often located deep within the engine compartment.

Expert Tip

To ensure the coolant always functions properly, you should follow these tips below:

Regularly Check the Coolant Level

Before each trip, the driver should open the hood and check the coolant level in the auxiliary tank. Make sure the coolant is always maintained at a safe level (between the Max and Min lines). If the coolant level is below the Min line, add some immediately.

Monitor the Temperature Gauge

While driving, occasionally pay attention to the coolant temperature gauge. If the temperature needle points to the Hot level, immediately stop the car, open the hood to let the car cool down, and check for any issues.

Do not open the coolant tank cap when the engine is running. If you need to stop the vehicle because the temperature gauge is too high or the vehicle has a problem, do not open the coolant tank to check the water level immediately due to the coolant. During boiling, the high pressure in the tank can cause strong splashes of water onto the face and limbs, causing burns.

You Should Use Specialized Coolant

To keep the engine durable, you should use specialized coolant. This type of coolant allows heat to be conducted quickly and doesn’t accumulate residue. At the same time, specialized water has an easily recognizable color, making it easier to visually check for coolant leaks.

Wrap Up

By looking at what happens when your car lacks coolant, you’ll understand the importance of maintaining it. Never overlook small symptoms, as they can lead to irreparable disasters that could cost you a fortune.
