Now is the time to take the four bolts that hold the wheel bearing to the knuckle. From the backside of the knuckle these are easily visible next to the Cv boot. A 14mm socket is your go to for removal, if your vehicle is older or rusty they can be difficult to remove.

We can now locate the brake caliper bracket and remove the two 14 mm bolts that hold it on. You may now slide the caliper off and hang it out of the way with a bungee cord or wire hook.

If you are hearing a nice humming noise from the rear of your car, it is highly likely to be one of the rear wheel bearings. If you have access to a lift you can use a stethoscope to listen to the backside of the hub and discern which is the unit that needs replacement. Otherwise you can do your best by listening inside the car while someone else is driving, sometimes you get a better ear from a different seat.

Here is your view with the axle nut and rotor removed. You can use a small punch on the center of the axle shaft it doesn’t move freely back and forth. This will help when removing the hub from the shaft.

All DIYS and installs should be performed by trained individuals. Understand your skill level and always take the proper safety precautions when working on a vehicle. I can assume no liability for damages to you or your vehicle via these guides. There is only one of you and you are very important to many people, keep this in mind!

Established in 1998, Luoyang Jiawei Bearing Manufacturing Co., Ltd. (LYJW) is a professional manufacturer of slewing bearings and we can design and manufacture single-row ball slewing ring bearing, double-row ball slewing ring bearing, three-row roller slewing bearing, ball-roller combination slewing ring, crossed roller bearing, crossed tapered roller bearing, slew drives and custom bearings.

With reasonable design, light weight, high load capacity and excellent versatility, It is widely used in hoisting machinery, mining machinery, construction machinery, port machinery, marine machinery, medical equipment, metallurgical equipment, electrical equipment and high-precision precision machinery, radar machinery and missile launchers and other large-scale rotary devices.

The sealing of the slewing bearing, on the one hand, is to prevent the leakage of filled grease, on the other hand, is to prevent the outside dust, impurities and moisture from invading into the exterior of the bearing and affecting its work. The sealing ring of LYJW slewing bearing is made of nitrile rubber material, which is resistant to high temperature and corrosion.

Due to the need to transmit force, slewing bearings usually have teeth on one of the rings. The toothing is generally normalized or quenched and tempered. Depending on the application, the gears can also be full-tooth hardened or single-tooth inductively hardened. Single tooth inductively hardening can be divided into full tooth hardening and tooth foot (flanks and base) hardening.

As with most Subaru products they are symmetrical side to side. So if you are picking up a wheel bearing either side takes the same part number. Make sure to pick up a new Cv axle nut to torque it back down properly.

Double check for proper brake operation before taking a test drive. Then move very slowly testing that the brake are operational, after you check that on your list you can go for a quick drive and then return to double check your work.

This is easily the most difficult part of the bearing removal. Feel free to spray copious amounts of rust penetrant to make everything easier. Some are more difficult than others, but after sometime it should break free.

LYJW is a professional manufacturer of slewing bearings and we can design and manufacture slew ring bearings, precision bearings, slew drives and custom bearings for construction, engineering, mining, marine, chemical, military, wind turbine, medical equipment, and many other industries. By virtue of expertise team, advanced manufacturing technologies and strict quality management system, LYJW takes the lead in the R&D of slewing bearings, which are designed with reasonable construction, light weight, good load carrying capacity and high versatility. The bearings’ diameters range from 200 to 15000mm and the accuracy covers PO, P6 and P5 class. Now, we can manufacture CCS, ABS, BV, GL and other certified bearings. We adhere to the business principle of “Quality and Integrity” and we’ll keep providing outstanding bearings and superior services to serve global customer.

Located on the top of the knuckle behind the brake rotor backing plate you will find the abs sensor. I remove this to make sure it isn’t damaged when removing the bearing and shifting the axle around. It is a single 10mm bolt and then it just needs a bit of wiggling to remove it. Be careful not to damage it, it is a plastic bodied sensor.

Here is our axle nut, a decent impact can break this free easily. You can also see the the two threaded holes on the brake rotor that can help easily remove it.

You can remove the axle nut now with your 32mm socket and impact gun. Once it is removed this is a good time to check that the axle slides in and out, it can often become seized by dirt and rust. If it won’t move you can use a punch to help free it up, you may even need an air hammer for those really stuck Cv shafts.

It’s that time again to start another repair and like many other repairs you will be lifting the vehicle up. This repair involves plenty of hammering and prying, so make sure your vehicle is on jack stands and very stable to keep from hurting you or any helpers.

Slewing ring is also called slewing ring bearing or turntable bearing. LYJW provides a variety of slewing rings, including Four-point Contact Ball Bearing, double-row ball slewing ring bearing, single-row crossed roller bearing, three-row roller slewing bearing and ball-roller combination slewing ring. The outer diameter of slewing bearings ranges from 100 to 15000mm to meet various requirements of different applications. Slewing rings can be manufactured without a gear, with an internal gear or with an external gear.

Once the hub begins to come free you most likely will see the backing plate has come with the bearing. Holding the backing plate and hammering in a circle will break the hub bearing free finding it's way to the floor.

Also up on your list of necessary tools are a Pry bar with hammer cap, your favorite hammer, 32mm axle nut socket and a good old ratchet or Milwaukee 3/8ths electric ratchet if you are me.

You can now place your new bearing inside the backing plate, the holes will line up when it is in the proper orientation. Using your hand you can start to spin the hub bolts back in. With one bolt started you will find the others line up and can be installed.

With all the bolts removed we can break the hub free and make room for the new unit. I have had great luck using my smaller pry bar with a hammer striking handle on it. Another option is a flat chisel to separate the knuckle from the bearing. The backing plate has a reinforced piece of metal across it that you can use your pry bar/chisel to break them free of one another. Once one side starts to separate you can move to the opposite side to keep it coming out evenly.

Get your impact guns ready! I use a Milwaukee 1/2 impact for lug nuts and axle nuts. The Milwaukee 3/8ths impact takes care of the rest of the bolts.

This is a tough one to gauge, if you have a rusty underbelly of the car. Get ready for a bit of a battle. For those with less rusty Subarus you will spend a good 30-50 minutes with your car. I recommend soaking everything behind the dust shield with rust penetrant to help you along in this.

Up next will be removing the brake rotor, make sure your parking brake isn’t set before doing this. My favorite technique is using a threaded bolt inside the rotor, running it down will push the rotor off of the old hub.

With those bolts installed you can start working backwards to put everything back together. Make sure your parking brake shoes are center and the brake rotor pops back over them. If they are a little off the rotor should help recenter them when it is installed. Also make sure to properly torque your rear axle nut and stake it to keep everything together.

Line the holes up a best you can You can use a screwdriver to help. Having the axle nut on will keep the hub the from coming off.

Subaru’s and wheel bearings… a match not made in Heaven. Some might even think they hate one another with a passion. Lucky for us Subaru decided to use bolt in hub bearings after 2008 on basically all their vehicles, this will be the style we are replacing today.
