Why Is Your Car Shaking and How to Fix?

Shaking in a rocking chair can be very relaxing but having the same experience when you are driving a car or even is alarming. A vibrating vehicle is not good news. However, the truth is even your newly purchased auto can show these signs. There are many causes of this disturbing incident, but don’t worry, in this article, we are about to show you the best ways to diagnose the roots of car shaking and the detailed guide on how to completely eradicate this problem. Now, let’s begin!

6 Main Reasons Explaining When Your Car Shaking

Imagine your car shaking all the way in the 20 miles journey. Annoying right? Car vibrates can cause serious accidents too. If you detect any such problem, you should diagnose for finding out the cause and take it to a repair shop. Here are the six most commonly occurred reasons for the vibration of an engine:

Wheels Out Of Balance

It is obvious that the most common problems which cause vibrating is by the wheels. You can easily recognize this when you feel the vibration in the floorboard and driver’s seat when driving at high speed.

Unbalanced wheels not only makes it difficult for driving, but also causes car shaking and vibrating. Once the wheels are not in their good conditions, drivers will unable to control their own speeds and directions, which can easily cause accidents. So this is definitely something driver must pay attention to.

Spark Plugs

Believe it or not, this is also one of the most famous car causes that often being ignored. But remember, spark plugs play an essential role in the process of driving. So if your car shaking, check the spark plugs.

When you have a broken or faulty spark plug, the engine will vibrate and cause misfire, which can damage the car system. However, unlike the first problem, you can easily fix this by changing a new plug.

Worn Tie Rod Ends

Another simple but unexpected reason for car shaking is the tie rod. Yes you are correct, it is the one connects the wheels to your car’s steering. These tie rods keep your wheels in the same direction, so drivers can easily adjust and change direction by controlling the steering.

Now here comes the scary part: When the tie rod ends begin to wear out, the wheels will go to different and separate ways. Beside from terrifying misdirection driving, this will also cause vibration.

Clogged Transmission Filter

Transmission filter is an important car part that requires a lot of attention. If this filter becomes clogged, the car will vibrate when reaching highway speed.

In order to fix this problem, all drivers need to do is replace the offending transmission filter.

Worn Uppers Strut Bearings

Talking about the struts, worn uppers strut bearing is another common reason when we discuss about car vibration. Just like other problems of your car shaking when carrying too heavy or going too fast, a worn uppers strut cause vibration.

A full checking service from car mechanic is what we would suggest, since the worn strut bearing problem can be quite hard to find. The professional mechanic will know when to fix or replace them.

Low Transmission Fluid

It’s one of the most familiar causes of engine vibration. If the level of transmission fluid runs low, your car will shake upon acceleration. It needs immediate attention because the shake it creates is quite intense.

There are more causes which your beloved car vibrates. The problem can arise for a bent axle, spark plugs, worn ball joints, loose hoses, and many other reasons. You should be careful and take the car to a service center if it shows any vibration while driving.

Wheels Out Of Balance

causes of engine vibration
One of the most popular reasons of engine vibration is unbalanced wheel.

As driver, unbalanced wheel is without a doubt the most annoying problem. Not only your car vibrates, drivers can also get into accident for uncontrollable movement. Yet again, every problem has its own way to resolve. Understanding the wheel can help you fix them by your own.

With a Balancer

Along with a bubble balancer, there are some tool you might need to carry with:

  • A flat end screwdriver
  • A jack
  • A lug wrench
Step 1: Remove The Wheel Weights

Before re balancing the wheel, there are various weight you already have on the wheels. So it is wisely to take them all out in order to balance them much easier and more accuracy.

Step 2: Remove The Wheels

After all the weights have been taken out, driver can now remove the wheels. Be careful since the wheels are heavy so you might need a helping hand.

Step 3: Clean The Wheels

Before balance the wheels, we suggest to clean all the dirt from the wheels. Drivers should focus on cleaning the rim and the tread of the tires. Wash them with water in order to be much cleaner while balancing, and remember to let them dry.

Step 4: Balance The Wheels

Many car owners here might have seen the balancer at least once, yet only few of you can actually know how to manage it. In order to make the balancer works, all you need is to turn it on and put the wheel on it. If you want to use dynamic balancing , you need to spin the wheel. On the other hand, if drivers use static balancing, just wait until the tires get back into a stationary position and it is all done.

Step 5: Mark The Spots And  Put The Weight Back On

Don’t forget to use chalk to mark the spots. These points are the place for drivers to put the weights in case of unbalanced wheels.

After that, returning the wheel weights to its position. This will help the wheel to stay at the right shape.

Step 6: Recheck And Adjust The Wheels

After the connection, it is time to make sure everything is right: Recheck and adjust the balance of the wheel. You should guarantee that the movement is smooth enough. If they stay in a perfect line and move without any problems, you are good to go.

Step 7: Return The Wheels Back To The Position

Last but not least, car owners should tighten the lug nuts, lower the jack in order to set the wheels to its position.

Without a Balancer

Even without machine, drivers can still balance the tire by themselves. Yet it can be very tricky sometimes. Also in order to do that, you might need a lot of tools to remove the weights and wheels.

Step 1: Remove the Weights And Debris

In order to balance the wheel and avoid car shaking, you need to find out which wheel can be the cause. After that, remove all the weights and debris from the tread for the following step. We also suggest to clean the wheel before doing anything else.

Step 2: Re-install The Weight

This step is based on pure experience: You can install the weight on the top side, then rev the car from 0 to the speed which your car starts vibrating. If the car still vibrates, replace the weight from that position to the position 45 degree to the right. Then accelerate.

Step 3: Solve The Problem

Continue with that for at least 3 times, and eventually you will find the spot. Especially the rear tire imbalance may have been insignificant while it was at the back, so it is very easy to spot. Drivers then can add more weights and complete the balancing.

Spark Plugs

If your car shaking, you know where to solve problem

Spark plug is one of the most important car parts, since it control the working function from Petrol and LPG Gas powered cars. It channels and ignites the fuel. When it broken, your car vibrates and has many different problems. And just like all other parts, they wear out overtime and can be fixed quite easily. Here is how we can repair them:

Step 1: Locate Old Spark Plugs

You need to locate the spark plugs in your vehicle. In order to do that, firstly you must open the car bonnet. The spark plugs are usually located at the engine end of a 4-8 wires bundle, under the plug covers.

On a 6-cylinder engine, spark plugs can be found on the side or top of the engine head. While on V8 and V6-cylinder engines, they are separated on engine sides evenly. On a 4-cylinder engine, they are located on the top or side of the engine, but in a row.

In some four-wheel vehicles, you will need to remove a few parts in order to see the spark plug wires, then trace them back in order to find the plugs. We suggest you to also check the gap and inspect the for any damage on the wires while tracing the plugs.

Step 2: Remove The Spark Plugs 

Always remember to let your car cool down a little bit before trying to remove the spark plugs. The entire engine and plugs might get extremely hot if your car has been running for a while. Drivers can gather their tools while waiting.

Firstly, pull the wire plug by gripping it at the bottom, it will reveal the plug. You must not yank on the wire to pull out since this will ruin spark plug lead. After that, drivers should fit your socket wrench with the bar, then use the ratchet to take the plug out slowly.

Step 3: Measure The Gap of The Spark Plugs

Even thought most plugs these days come preset according to the application and the model number, a double-check is always important.

If the distance of plug gap is higher than it should be, you can buy a new plugs, or try to change the gap. In order to do it, gently tapping a wooden surface of the plug with the gauge until it reaches the correct measurement. However, we suggest a replacement after every 20000 kilometers, since it is not that expensive and you can replace them at intervals for trouble-free motoring.

Step 4: Install New Plugs

As a good driver, the first thing you must do is to be sure the plugs are correct. There are thousands of different combinations of measurements and spark plugs, from the size to the price. So if you are not sure, share the information with auto parts dealers for advice.

To install the plugs, use the spark-plug socket to remove each plug from the engine. Then drivers can insert each hole with a new plug. Remember to not over-tighten them as you can strip the thread on the engine’s head, which can cost a lot of time and money to repair.

Drivers can even buy the torque specification just for the plugs in service manual in order to set up for the ratchet. After that, we recommend to use anti-seize lubricant on the plug threads if car owners has an aluminum engine. A small amount of dielectric silicone is also necessary to make the plugs easier to remove. However, drivers must remember to put the spark plug wire boot back on the plug, or you might cause the engine to misfire.

After that, remove the wheel to locate the outer and inner tie rod end

Step 2: Remove the Tie Rod End

Firstly, car owners should loosen the pinch nut, which holding the outer tie rod end in place and preventing unpredictable impact. This loosening allows drivers to twist the outer tie rod end.

Secondly, move the nut up to touch the outer tie rod end

Thirdly, drivers can now remove the cotter pin and throw it away. This part is impossible to reused. Following the cotter pin, castle nut is the next part to be taken out. It is the nut that the cotter pin went through and connect the steering knuckle and tie rod end.

Fourthly, remove the outer tie rod end from steering knuckle and inner tie rod end. We suggest using a ball joint separator or a tie rod puller.

Last but not least, remove the inner tie rod end. In order to do this, take a pair of pliers and remove the clamp from the boot and break the clip on the far side. After that, twist the inner tie rod end counterclockwise and pull it off of the car.

Step 3: Replace the Tie Rod End

After the removal, drivers might check to make sure the new tie rod end is comparable to the previous one. If they are the same length, shape and size as they should be, those tie rod ends are ready to be replace and install.

Following the comparison, you can now thread the inner tie rod end into the steering gear and slide the boot back onto the rod. It is essential to thread the pinch nut, tighten the castle nut back and replace the cotter pin after connect the tie rod end to the steering knuckle, since this will secure its position. After that, you can start replace the wheel and lower your car back to the ground.

In order to drain the fluid, a bucket or container is the tool you need: Place it underneath the transmission drain plug to collect the fluid.

Remember to use your socket wrench for easier job. This also allow the transmission to flow out completely.

Step 3: Clean The Pan 

After that, remove the bolts and old gasket seal from the pan. You can use the scraper to scrape any dirt or debris around the edges, since this is where you apply the new gasket seal.

Step 4: Install The New Pan Gasket Seal

A layer of gasket seal can be used to apply to the gasket. And now you can easier install the new pan gasket seal to the transmission.

    Hi,

    Thanks for your explanation about the possible cause of engine vibrating when at idle & running mode as well. My car is 2007 make Hyundai Santafe. Km run is about 125607 till date. It’s a pretty good car but over the last two years my car was used roughly & extensively & as a result started to show the following issues:
    1. Strong vibration of engine for the pad one month n getting even more stronger vibrations now
    2. Transmission of manual gear is getting hard especially after starting the car in the early winter morning. And later during the day the gear transmission to 1 & 2 is getting hard & doesn’t transfer the gear smoothly

    Recently showed to the mechanic, checked the fuel injectors & says working fine but vibration still remains same rate. Mechanic checked & replaced the front right hand side engine mounts but vibration is still there. Now the mechanic says he will do the fuel injectors servicing but I don’t know doing this would solve the vibrating issue. I am spending my time & money for replacing something which is not cause of issue. I m worried & assume that vibrating issue could be the flying discs which facilitates smooth transmission of gear when car is on the road ( sorry unable to name correctly).

    Please help me to diagnose the main cause for strong vibrations especially when the car is idle mode & when driving at low gear. I m from Bhutan where we don’t have an expert car mechanic to deal with the problem effectively.
    Thank you for answering my query please.
