How to remove the bearings ?

Step 1: Removing the hub/wheel assembly from the vehicle is an essential first step in removing the bearings.

This will typically require lifting the vehicle and using a lug wrench to loosen and remove the nuts holding the wheel.

It is important to follow any recommended practices for lifting and supporting the vehicle and removing the lug nuts to ensure the safety of the person performing the repair and prevent damage to the vehicle.

Suppose you must familiarize yourself with the recommended practices for lifting and supporting your specific vehicle make and model.

In that case, it is a good idea to consult a repair manual or seek guidance from a professional mechanic.

Some vehicles may have specific jacking points that should be used, and others may require the use of specialized equipment such as a hydraulic lift.

Once the lug nuts have been removed, and the wheel is free from the vehicle, you can carefully lift it off and set it aside.

If the hub is equipped with a brake rotor or drum, you may need to remove it before proceeding to the next step.

Step 2: The inboard and outboard bearing cones are the two halves of the bearing that are seated inside the hub.

They can usually be removed by gently prying them out with a flat-headed screwdriver or a bearing separator tool.

It is important to handle the cones with care and set them aside for inspection, as they may show signs of wear or damage that need to be addressed.

To remove the inboard cone, you may need to locate and remove any retaining rings or clips that hold it in place.

These are typically found on the back side of the hub, and they can usually be removed with a pair of needle-nose pliers or a small pry bar.

Once the retaining rings or clips are removed, the inboard cone should be able to be gently pried out of the hub.

To remove the outboard cone, you may need to remove any dust seals or shield plates that protect it from dirt and debris.

These can typically be pried out with a screwdriver or a small pry bar.

Once the dust seals or shield plates have been removed, the outboard cone should be able to be gently pried out of the hub in the same manner as the inboard cone.

Step 3: The bearing cups are the bearings' outer shells pressed into the hub. To remove them, you must use a mild steel drift or cup driver.

This tool is a rod with a tapered end to push the cups out of the hub carefully.

It is essential to be gentle and to apply even pressure to avoid damaging the hub or the cups.

It would be best if you also were prepared for the cups to put up some resistance, as they will be tightly seated in the hub.

To use the drift or cup driver, you will need to carefully insert the tapered end into the center of the cup and apply even pressure until the cup is fully seated in the hub.

You may need to gently tap the drift or cup driver with a hammer to help seat it, but be careful not to apply too much force, or you may damage the hub or the cups.

Once the cup is fully seated, it should be able to be gently pried out of the hub using a flat-headed screwdriver or a small pry bar.

It is essential to repeat this process for both the inboard and outboard cups, as they may be different sizes and require further drift or cup drivers to remove them.

Once both cups have been removed, you can carefully inspect them for any visible signs of wear or damage.

Inspection the old bearings

Inspect the bearings for visible damage signs, such as cracking, pitting, or excessive wear.
Check the bearings for proper installation, ensuring they are seated correctly in the bearing bores and the cups are fully installed in the hub.
Check the bearing seals for damage or leaks.
Inspect the bearing races for damage or wear.
Check the bearing clearance, which is the free movement within the bearing. This can be done using a dial indicator or a feeler gauge. The bearing clearance should be within the manufacturer's recommended specifications.
Check the bearing preload, which is the force applied to the bearings to remove any excess clearance. This can be done using a torque wrench and a load cell. The bearing preload should also be within the manufacturer's recommended specifications.
The bearings should be replaced if any of the above checks reveal damage or wear.
It is also important to properly lubricate the bearings. This can be done by cleaning the bearings and applying high-quality bearing grease. The grease should be compatible with the bearings and should be applied in the correct amount.
When inspecting and handling the bearings, it is important to use caution and follow proper safety procedures. This includes wearing protective equipment such as gloves and eye protection and using appropriate tools and equipment.
It is also a good idea to keep accurate records of the inspection and any maintenance or repairs performed on the bearings. This will help to track the condition and performance of the bearings over time and can help identify potential issues before they become serious problems.

In summary, the inspection of old bearings is an integral part of maintaining a vehicle or machine's overall health and performance.

It involves checking for visible signs of damage or wear, ensuring proper installation and lubrication, and verifying that the bearing clearance and preload are within the manufacturer's recommended specifications.

Proper inspection and maintenance of bearings can help to extend their lifespan and prevent costly breakdowns or failures.

How to install the new bearings?

Step 1: Thoroughly clean the bearing cups and cones before installation.

This is important to remove any dirt or debris that could cause damage to the bearings during installation. Use a clean, dry cloth or a low-pressure air hose to remove any dirt or debris from the surfaces of the cups and cones.

Step 2: Lightly coat the outside of the bearing cups with oil. This will help protect the cups from damage during installation and make it easier to drive them into place.

Use a high-quality bearing oil or grease for best results.

Step 3: Using a cup driver, carefully drive the bearing cups into the hub bearing bores.

A cup driver is a specialized tool designed to fit over the bearing cups and apply even pressure as they are driven into place.

Use the correct size cup driver for the bearings you install.

Step 4: Use a feeler gauge to check for gaps between the cup and the shoulder.

The feeler gauge is a thin metal strip used to measure small gaps or spaces.

Place the feeler gauge between the cup and the shoulder and check for any gaps.

If there are any gaps, use a hammer and a block of wood to gently tap the cups into place until the gaps are eliminated.

Step 5: Inspect the bearing cups to ensure no damage occurs during installation.

Look for any cracks, deformities, or other signs of damage.

If any damage is found, the cups should be replaced.

Step 6: Lubricate the bearing cones according to recommended practices and install the wheel assembly.

Use a high-quality bearing grease or oil to lubricate the cones, and apply it in the correct amount according to the manufacturer's recommendations.

Make sure to fully seat the cones in the hub before installing the wheel assembly.

In summary, installing new bearings requires a thorough cleaning, proper lubrication, and careful installation.

It is essential to follow the manufacturer's instructions and recommended practices to ensure that the bearings are installed correctly and function properly.

Proper bearings installation can help extend their lifespan and prevent costly breakdowns or failures.
