Car Suspension – A Quick Guide

Can you think of a smooth car ride without a good suspension? Simply, No! 

Today, we are going to discuss everything about car suspension such as what it is and its function, how suspension adds comfort to your car ride? Let’s dive into the sea of knowledge. 

Car Suspension

Car suspension is a complex system that includes rods, pistons, shock absorbers, etc. It is a vital part of every vehicle that helps in preventing the car and its parts from any damage. You must have seen that on an extremely bumpy and uneven road, the vehicle always experiences a lot of wear and tear. It is the suspension system of the car that helps in saving the whole car’s system from excessive damage.  

It has been seen that sometimes we fail to judge or ignore the arising abnormalities in the suspension systems. So, it is better to notice it before it results in a big part’s failure. Before jumping to the problems of the car suspension system, let’s discuss the function of vehicle suspension systems.

What is the Function of Suspension?


The car suspension system is the prime mechanism that divides the car’s bum from the road. A good vehicle’s suspension system prevents your car from excess shaking or vibrations. No matter how smooth your road is, it is completely dangerous to ride a metallic heavy body on the wheels with a bad suspension system. Take an example of trains, they don’t have suspension systems that is why we experience harsh riding. Whereas, in cars, the rubbers of the tires keep the jerk up to an extent while the rest of the work is done by other suspension parts.

Let’s have a look at different components of car suspension and their work. 

Important Parts of Suspension


Different components play a key role in suspension systems. Have a look at them and their work.

1) Coil Springs

The springs are the parts of a suspension system that sucks up the whole jerk when the car passes through bumps or holes in the road. Instead of using springs, some metal rods are being used in some cars. 

2) Wheels and Tires

These are components of the suspension system connected outside. Without tires or wheels, you can’t ride as the car moves when tires move. 

Most of the impact of the bumpy and potholes is exerted by the tires. Besides, braking, accelerating, and drifting of the car have a huge impact on the tires. Therefore, it is very important to have an adequate amount of treads and air pressure. All these things can smooth the drive. 

3) Shock Absorbers

They work along with car springs to diminish the effects of potholes and bumps. If the shock absorber works well then only it can support car springs. All this helps in reducing the bouncing while the car is at high speed. 

Inside shock absorbers, there is a thick oil that helps it in functioning well. In case a leak out happens, it may lose its proper functioning.

4) Rods/Linkages

Several rods are interlinked with other parts of the suspension system. These rods are made up of metal that makes it more durable and long-lasting. With a strong devastating accident may break or damage a rod.

5) Bearings/Joints/Bushings

These are the parts that connect the suspension system with other larger car’s components. Not just this, the components such as bearings & bushings help in sliding and twisting actions of other auto parts. 

If the suspension bushing is made up of rubber then it may wear out quickly. The joint may lose after a certain time. It is one of the reasons that whenever the suspension system wears out, it is because of problems in the bushing, smaller joints, and bearing. 

Signs of Car Suspension Problems-

1. If You Rides Roughly

If your car is not offering a smooth ride then it must be because of the poor suspension system. The bumpy road or potholes are responsible for the poor suspension system. When the suspension is not good then you must get more vibrations or jerks while having a drive.

2. Drifting or Pulling While Turns 


If you are feeling a pull or drift while your car takes a turn, then your vehicle has a poor suspension system. It also clearly shows that the shock absorbers are completely worn out and need a fast replacement.

3. Dips/”Nose Dives” While Applying Brakes 

When the shock absorbers get worn out, you are likely to sense your vehicle’s body lurching in the forward & downward direction while applying brakes. It is a scary and dangerous situation where due to a bad suspension system the stopping ability reduced by 20 percent.

4. Uneven Tire Treads

Have you seen uneven treads on your car tires? In case you ever noticed them, you must visit a mechanic as soon as possible. It could be due to the misalignment of car tires, bad suspension system, uneven amount of air pressure in cars. 

5. Damaged Or Oil Leakage of Shocks

Take a look under the car, notice at the shocks or struts of the suspension system. If you see leakage of grease or oil then there is a huge chance that they have a leaking fluid filled in the shocks. And there is a good chance that they are not working completely. It is the best time to replace the shocks as soon as possible. 

How To Maintain a Car’s Suspension?

There are a lot of factors that affect the life and working of a car’s suspension. To enjoy a smooth ride, you need to maintain the suspension well. Here are some of the optimum things that you can do for your suspension.

  • Check your suspension systems thoroughly regularly. You can check it after getting your car serviced or after an oil change.
  • Inspect the rubber bushing on the track bars struts rods, etc.
  • Check every part of the suspension system to locate the cracks, oil contamination or missing parts, etc.
  • Check the quantity of grease of your car as it may leak out.

Don’t allow your car suspension system to wear and tear to the point where it affects your other car parts too. Repairing or getting car service is a much easier and more pocket-friendly option than buying a new car. Ne must know the functions, parts and signs of a bad car suspension system.

Engine Knocking Sound- What, Why, How?

Have you noticed knocking or tapping sound from the hood of your car? If yes, then surely your engine is making sounds and you should not ignore it. We know the engine is a vital part of an automobile that keeps our vehicle moving smoothly. The automobile experts never recommend anyone to ignore such problems. Rather one should take required measures to solve them on the prior basis. 

Otherwise, repairing or complete replacement of a specific part may cost you heavy. The engine should operate smoothly from the point of ignition of a car. There are certain sounds that can knock the engine. But the difficulty is to locate it and reach the actual cause of the problem. 

Well, we are here to help you out the actual cause of engine knocking sound. And how you can prevent it and repair your engine’s sound. 

What is Engine Knocking Sound?

It is also named as spark knock, pinging, and detonation – all or one of them may occur when the car engine doesn’t get even supply of fuel and air. It lacks the flame that is produced from the spark plug when it comes in contact with the mixture. When the mixture of air and fuel strikes the cylinder of the engine, it starts in a normal way  but when the engine’s cylinders get uneven mixture then it gives shocks and leads to annoying sounds. All these things damage the engine and pistons.   

Common Causes of Engine Knocking Sound

  • Faulty Spark Plugs

Let us discuss the work of spark plugs of a vehicle. Well, it ignites the mixture of air and fuel by delivering an electric spark. Without a spark plug, neither engine could not work nor your car could start. Just like other auto parts, this essential part also becomes faulty over time. A faulty spark plug often produces a knocking sound. A damaged spark plug needs a replacement and it’s not that costly. Besides, the time taken to replace it is too little. 

  • Poor Fuel Octane Rating 

Fuel has an octane rating. If you are putting a poor octane quality fuel in your vehicle, it will generate engine knocking sounds. Octane rating is the ability to resist premature detonation of the air-fuel mixture in the engine. This can be prevented if you use high fuel octane quality.  

  • Whimpering Belt 

Yes, it is another important part of the car. If you found a high-pitched sound then you might have a faulty belt. When a belt slips, stretches or coating with some kind of oil or dirt then it starts making sounds. It happens too often in extreme winters.

  • Carbon Deposit

It has been seen that the terminals of an engine’s cylinder get clogged with carbon over time. The mixture of fuel and air deposit on the terminals that leads to annoying engine knocking sounds. 

Preventions of Engine Knocking

Prevention can be made if you repair or replace problematic parts quickly and get your car serviced at the right time. If you are following the below-mentioned points, you could easily resist the engine knocking sounds.  

  1. Always Use Premium Unleaded Fuel Your Car- Using low-grade gasoline for your vehicle is one of the main reasons that may crook your engine and results in engine knocking. The experts always recommend premium quality fuel with higher octane fuel. Besides, it helps in boosting the mileage of a car.

  1. Must Use Fuel Detergent- Although most of the mixture of gasoline and fuel includes fuel detergent. But if you feel your car is having engine knocking sound then you may require a better pungent to lower down the sound. The right fuel detergent that cleans up the carbon content that sometimes builds up on the fuel lines results in engine knocking.
  1. Change Faulty Spark Plugs- If your vehicle has been serviced recently then there is a little chance that the spark plugs were replaced actually. Some inexperienced people don’t bother to replace it while servicing the car. With time they might stop sparking and stop giving appropriate spark. Fitting the right kind of spark plugs is very important to prevent engine knocking.

In the end, I would mention that one should not ignore the engine knocking sound. Change the oil of your car regularly. Keep an eye on the low oil level and worn-out oil. As it may contribute to poor lubrication among various parts that worn out the engine and related-components completely.


Intake Manifold Runner Valve – All You Need To Know About

The mechanism of vehicles is too complicated for a layman. There are numerous parts in a car. Every auto part has its unique work. The manufacturing of these parts is also done by expertise at different locations. But, yes you can easily find them at one auto shop if you really wanna buy them. Well, in this blog, we are going to discuss intake manifold runner valves. 

Before beginning, let’s clear some of the important things beforehand. In the automotive world, Inlet-Manifold and Intake-Manifold are the same.  

What is Intake Manifold Runner Valve?

The intake manifold is a vital part of an engine. It supplies a mixture of air & fuel to the engine as required while ignition. The valve has multiple tubes that regulates the inlet air from plenum to the inlet terminals. The tube like structures are known as Runners as these terminals help in flowing of gas into them. The length of the runner depends on the internal mechanism and design of the intake manifold valves.  

What Does an Intake Manifold Runner Valve Do?

The inlet manifold runner controls the runner values. These are butterfly valves that open and close to let in the high-pressure air in the cylinders. This process is applied to almost all the engine speeds. The goal is to maximize the manifold pressure. It is very important to have a flawless intake manifold control valve because it will close with a minimal vacuum.

How the vehicle’s engine activates the air-fuel mixture does not depend on the inlet runner valves. This auto part ensures the successful operations of your engine without improving the state such as superchargers and turbochargers.   

What are the Signs of Intake Manifold Runner Control Valve Failure?

While an intake manifold runner is nothing to do with the engine operation but it helps in increasing the engine performance and its efficiency at low speed. In case of faulty or complete failure of the intake manifold runner, it results in lower engine performance. In general, when an intake manifold runner valve fails it shows some signs that are identified easily. All you need to care about is to notice them and solve them in advance. 

  • Difficulty While Starting the Engine

This one is the foremost sign of faulty intake manifold valves. While you start the engine it finds difficulty due to the inappropriate position of butterfly valves that often provide hindrance while starting the car engine. It has been seen that you may require more cranks while starting the vehicle as compared to the normal start. 

  • Poor Engine Performance & Increased Fuel Efficiency

When you may notice a poor performance of your car’s engine, it is a clear sign of a faulty intake manifold valve. Due to this, you may experience some misfires, a lower power level, a decrease in acceleration, stalling, poor mileage, etc. 

  • Power Engine Torque

The intake manifold valve helps in enhancing the low engine speed torque by accelerating the airflow speed. It improves in removing engine knocking by offering thorough combustion. While the RPM of the vehicle is more, long and short paths open wide that permit more air to let inside the cylinder. If the intake manifold valve stops working, there will be nothing that can control the manifold valves that eventually will not enable to regulate the ideal airflow.

Want to Replace the Intake Manifold Valve?

In case of a damaging or faulty intake manifold valve, the experts always recommend replacing it.  The price of intake manifolds can vary from store to store. You can buy it from The Auto Parts Shop at an affordable cost price. All you need to do is to share your requirements such as- brand, series.
