Many people love their cars. Some people cannot do without a vehicle even in a single day, and this is the reason why even a small breakdown can give them sleepless nights.
Buying a new car is quite cheap when compared to maintenance. For a vehicle to remain in good condition, it needs regular service.
A car is an excellent condition that will save you lots of bucks since there will be minimal wear and repair of major components.
Any sound emanating from the vehicle could be a signal that there is a problem that needs an immediate fix. The production of squeaky sounds can be irritating, and if it remains unattended, then it will result in more complications that can even empty your bank account.
Squeaky sounds emanating from the alternator bearing could affect the car battery, and this will later hinder your movement.
If you love your car, then you will be expected to consider bringing on board a car mechanic for diagnosis of the problem. However, this is something that you can still fix at home without any help so long as you have the right equipment.
In this article, I am going to show various ways on how to fix a noisy and squeaky alternator bearing step by step. Take your time to read through slowly and comprehend every step.
How Do I Know If My Alternator Bearings Are Bad?
Alternators are excellent instruments in a vehicle. The device ensures the car battery is charged whether the car is parked or it is moving.
The part of the vehicle also helps to generate power so that lights and other vital electronics can operate. The presence of bearings in the alternator helps to rotate the rotor inside the alternators to produce the required power.
Therefore, if the car experience a low generation of power, then there could be a problem with the alternator bearings.
Sometimes, you will experience the production of squeaky sounds that tend to be irritating, and this should also be a clear indicator that the alternator bearings are bad.
Therefore, you will be required to replace the alternator immediately so that it can prevent the occurrence of another problem.
Shopping for this device can be a daunting experience, especially if you are a new car owner or you do not have any experience with vehicle parts.
I always advise such types of car owners to consult their car mechanics for help since these are some of the crucial parts in a car.
The mechanic will remove the worn-out alternator and replace it with a new one. The model of the alternator is more comfortable to identify since they tend to have numbers.
What Causes Alternator To Make Noise?
Alternators play a very crucial role in a vehicle. If you hear any sounds, then it is a clear indication of a future breakdown.
Diagnosing the problem as soon as possible will save from a world of problems. If you are the kind of person who tends to be ignorant, then do not try this in your car.
You are likely to get stuck in an inoperable vehicle in the middle of the wilderness where there is nobody to help. Identify the cause of the squeaking, grinding and humming noise then get it fixed immediately before hitting the road again.
Here are some of the possible causes of noise in an alternator. They include:
Worn Out Alternator Bearings
Alternator bearings that are worn out tend to produce a disgusting grinding or whining noise that can later make your car to breakdown.
These bearings enable the rotor to spin inside the alternator freely to enhance the generation of power that is essential in running of the vehicle.
These alternator bearings tend to fail due to excess heat and accumulation of dirt. Therefore, you will be required to replace either the entire system or only the bearings.
Loose Alternator Bolts
Some car mechanics focus only on money value rather than customer satisfaction. They tend to mount the alternator improperly, and this is the reason behind the noise.
Improper connection of the alternator can result lead to failure; hence, the production of squeaky irritating noise. Therefore, ensure the bolts have snug so that the alternator is secured in the right connection to enhance the charging system.
Problems with Alternator Belt
The belt helps to spin the rotor inside the alternator. This partwork side by side with the bearings. If one part fails, then the entire system automatically fails.
If the alternator belt is loose or excessively worn-out, then expect to hear some disgusting sounds as you hit the road. The best thing to consider is replacing the entire belt and ensure it will align so that it can function correctly.
Also, remember to tighten, and this will help to get rid of the unnecessary noise emanating from the alternator.
How Long Should An Alternator Last?
Many car owners tend to believe that the electrical power of the vehicle comes from the battery, but this is not the case.
The alternator is the main component responsible for generating power for various electrical accessories and other vehicle features.
However, the car battery also tends to produce power but in a small amount. These two parts are dependent on each other by the way.
According to research, alternator tends to last longer than car batteries. The life expectancy of the alternator depends on the description of the manufacturer.
The study shows that a good alternator tends to last for a couple of years that ranges between four to seven years. But this depends on a couple of factors like a number of miles covered by your car or how you drive your car.
Many manufacturers tend to claim that alternators of new cars tend to wear out after driving a couple of about one hundred thousand miles, but this does not happen in many cases.
The only thing to do is to pay attention to various warnings from the car and try as much as possible to fix them. Regular services and diagnosis of your car will help to keep it in good condition for an extended period.
How To Fix A Squeaky Alternator Bearing
Alternator rarely fails, and in case of such instances, then this is probably the bearings. These are the parts that are responsible for rotating the rotor to produce an electrical charge in the vehicle.
Excessive heat and dirt accumulation around the alternator happens to be the leading cause of alternator bearing failure.
You will start hearing a squeaky and grinding noise as you drive then later result in the alternator to fail. We recommend running some tests immediately so that you can avoid further problems in the future after hitting the road into the wilderness.
The first thing to do is to jump-start the car. Then try to do away with the jumper cables. If the car engine goes to sleep, then the alternator is the cause of the problem.
However, if the engine continues to run, then it could be the car battery. You will be required to charge the battery.
Here are tips on how to fix a squeaky alternator bearing noise. They include:
Switch off the running car engine and then check the alternator bearings. You should never insert your finger inside the alternator while the engine is running.
Open the car hood to locate the fan belt and then remove it.
Try to rotate the alternator using your hand. Also, reach out to the bearings and feel them as they turn.
If the bearings are rough or they produce squeaky sounds as you rotate, open the alternator and check their condition.
Replace them if they are worn out and align them in order. If the squeaky sounds persist, then it could be due to belt.
The noise from the alternator can be so disgusting, and it is advisable to replace them, but this is usually on a short term basis.
Getting the exact match bearings can be a daunting experience. The best way to solve the problem permanently is considering to replace the entire alternator.
Consult an expert in such a case and for a quick fix.
I recommend you bring on board a car mechanic to fix the issue rather than doing on yourself. Most car mechanics are professionals, and they know how to do it effectively.
