You`ll probably need to use a wrench (and/or a hammer) to remove the end of the hub and any anti-lock brake wheel that may be part of your hub. A special tool may also be needed to remove the central bolt. Then, the bearing assembly should come apart easily.

Loosen the lug nuts and lift the wheel using a jack.

For proper access to the internal components of the wheel whose bearings you`re replacing, you`ll need to elevate the wheel. Luckily, most vehicles come with a jack for just this purpose.

Driving conditions – driving through deep water or mud can cause your wheel bearings to fail. Water, mud or other contaminants such as dust or road salt could get past the seals and enter the bearing, polluting the grease and wearing away the bearings.
Typically, there is no maintenance required for your Subaru wheel bearings, but a replacement is usually needed after 100,000 miles of driving.
Squealing, Growling

The typical sounds of worn-out wheel bearings are squealing and/or growling. The sound intensifies as vehicle speed increases.

Two types of Subaru wheel bearing:

These contain a roller bearing with an outer shell cone and are pressed in with specialised equipment.

Besides bearings, hub assemblies contain the wheel speed sensor that controls your vehicle`s ABS braking system.
Along with grease, the bearing rotates in-tandem with the wheel`s rotation, the rolling motion of the balls allowing the wheel hub to rotate as freely as possible. The wheel bearing is housed within the hub assembly, providing the static connection with the hub carrier through an outer ring or `racer`.
Luckily, bearings aren`t difficult to replace, and most modern vehicles use either bolt-in or pressed-in bearings. With the right tools, you can perform this replacement by yourself: Park your car on a safe, flat surface and secure the wheels you aren`t working on with wheel chocks.

When replacing a wheel hub on an acura , do I have to replace the wheel bearing to? 1997 Acura RL
ANSWER : Hello – perhaps the question should be "Do I have to replace the wheel hub/bearings if one or more studs are broken off?". And, the answer is "No, simply replaced the broken studs." That is – unless the hub or wheel bearings were damaged by whatever incident broke the studs. If it is necessary to replace the hub, you are better off buying a hub/bearing assembly – even if you have a choice (for most new cars, you don’t). Replacing a bearing within a hub requires heavy duty press tools to press the old bearing out and the new bearing in. you need experience, comfort level and specialized tools for this. I would recommend having a wheel hub/bearing assembly replacement done by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

I hear an abnormal noise from front driver’s side wheel. It sounds like a wheel bearing but not sure.
ANSWER : A wheel bearing noise can be different between vehicles as some designs may vary a little. The most common is a roaring noise that may change when going around turns. It may be louder going in one direction or the other or just make a loud noise all of the time. The wheel hub presses into the wheel bearing. The hub is where the studs are for the wheel to be bolted onto the steering knuckle and the bearing provides the support for the wheel and weight of the vehicle. Consider hiring an experienced technician like one from YourMechanic who can come out and take a closer look at your wheel bearing noise to offer a more personal diagnosis.

When the dealer says u need to replace a wheel bearing, do they mean just the bearing or the bearing/hub assembly?

Do I need to replace the hubs to go back to factory wheel bolts.
ANSWER : You’re wise to go back to factory fasteners. While there are a few good quality aftermarket products out there for your car, most of the options are a kind of one-size-fits-all that involve spacers and adapters that change the design offset and lead to all kinds of suspension and wheel bearing problems. you should not need to replace the hubs as long as the threads are not damaged. It should be possible to extract the studs through conventional means. If a hub IS damaged, then there is no choice but to replace it. This will involve replacing the wheel bearing as well so it can get expensive. If this project is more than you want to take on, you can contact Your Mechanic to have a technician come to your home or office and change out your wheels for you

New wheel bearing hub assembly
ANSWER : Hello, yes it does sound like you have a bearing issue. That red ring is a seal located in the knuckle area where the bearing mounts, it is for keeping moisture and debris away from bearing. The important things to do when replacing this type of bearing is having the area clean and the proper torque on the fasteners. Most important is the torque of the large nut that connects to the half shaft. That torque gives that bearing the correct operating preload. If not torqued correctly the bearing will prematurely fail. If you’d like, a certified Your Mechanic technician can come to your location to look at this issue.
