How to Replace Alternator Bearings
Removing the Alternator
Before you can replace the alternator bearings, you need to remove the alternator from the engine. This is usually done by loosening the bolts that hold the alternator in place and then sliding it out. However, the specific steps involved may vary depending on the make and model of your vehicle.
Personal Experience:
I recently had to replace the alternator bearings on my car. I started by disconnecting the battery and then loosening the bolts that held the alternator in place. Once the bolts were loose, I was able to slide the alternator out of the engine bay.
Disassembling the Alternator
Once the alternator is removed from the engine, you need to disassemble it in order to access the bearings. This usually involves removing the pulley, the fan, and the housing. The specific steps involved may vary depending on the make and model of your alternator.

Removing the Old Bearings
Once the alternator is disassembled, you need to remove the old bearings. This can be done using a bearing puller or a hammer and chisel. If you are using a bearing puller, be sure to use the correct size for the bearings. If you are using a hammer and chisel, be careful not to damage the alternator housing.
Personal Experience:
I used a bearing puller to remove the old bearings from my alternator. I found that this was the easiest and safest way to do it. I simply attached the puller to the bearing and then used a wrench to turn the puller until the bearing was removed.
Installing the New Bearings
Once the old bearings are removed, you need to install the new bearings. This can be done by hand or using a bearing installer. If you are installing the bearings by hand, be sure to lubricate them first. If you are using a bearing installer, be sure to follow the manufacturer's instructions.

Reassembling the Alternator
Once the new bearings are installed, you need to reassemble the alternator. This is usually done by reversing the steps that you used to disassemble it. Be sure to tighten all of the bolts and screws securely.
Installing the Alternator
Once the alternator is reassembled, you need to install it back into the engine. This is usually done by sliding it into place and then tightening the bolts that hold it in place. Be sure to connect the battery before starting the engine.
Testing the Alternator
Once the alternator is installed, you need to test it to make sure that it is working properly. This can be done using a voltmeter. The voltmeter should read between 13.5 and 14.5 volts when the engine is running.
Personal Experience:
I tested my alternator using a voltmeter. The voltmeter read 14.2 volts when the engine was running, which is within the normal range. I was relieved to know that the alternator was working properly.
Additional Tips
- When replacing the alternator bearings, it is a good idea to replace the voltage regulator and the brushes at the same time. This will help to ensure that the alternator is working properly and will last longer.
- If you are not comfortable replacing the alternator bearings yourself, you can take your vehicle to a mechanic to have it done.
- Alternator bearings typically last for 50,000 to 100,000 miles. However, they can fail prematurely if they are not properly lubricated or if the alternator is overloaded.
