How To Change A Rear Wheel Bearing
Last Updated on Dec vii, 2020
Wheel bearings are used in both the forepart wheels and the back wheels. Each individual wheel has their own wheel begetting and it is possible for just one of those bearings to wear out while the others are still in good status.
Demand immediate assistance for your car problem? Conversation online with an expert:
That is why you lot won't necessarily have to replace all of your wheel bearings if only one is worn out. Many (dishonest) mechanics volition tell you that all demand to be replaced or both on the same axle. This is normally not necessary.
There are certain symptoms y'all can await for which indicate bad bicycle bearings or a mechanic will exist able to tell you lot if you lot have any wheel bearings that need to exist replaced when taking your motorcar in for regular maintenance.
Superlative 5 Bad Wheel Bearing Symptoms
To determine the status of your wheel bearings, there are 5 mutual signs you can look out for.
#1 – Uneven Tire Vesture
When bike bearings wear out, they tend to wearable out unevenly from the rest of them. This will cause the corresponding tire to have abnormal tire wear compared to the others.
In a normal situation where your tires vesture out, they would all be evenly worn out from just driving on them. So if they are unevenly worn out, it could very well be to a bad wheel begetting.
Of course, other issues such as a bad wheel alignment, unbalanced tires, and others could likewise exist causes of uneven tire clothing so don't assume it's the cycle bearings unless other symptoms lucifer upwardly.
#2 – Grinding Racket
A common symptom of bad wheel bearings is when your tires take a loud grinding noise coming from them. This is acquired when the wheel bearings lose their lubricity and build up a lot of rut within of them instead.
It will about exist like hearing 2 pieces of metal grinding together. Usually, you'll only hear the sound coming from 1 wheel rather than all of them because of how the wheels clothing out unevenly. The dissonance is almost noticeable while shifting or turning.
#3 – Steering Wheel Vibrates
If the problem gets actually bad so your steering bicycle volition outset to vibrate. Y'all'll notice this vibration when you bulldoze at slower speeds but the trouble will go worse as you step on the gas pedal and accelerate the vehicle.
A lot of people think this symptom has to do with unbalanced tires on their vehicle. While the symptoms of both are similar, vibrations from an unevenly balanced tires occur at loftier speeds.
Simply in whatever case, you should take your vehicle to a mechanic and have them officially diagnose the problem.
#iv – Vehicle Pulls to One Side
When a wheel bearing is worn and becomes corroded or pitted, the smooth lining which bearings require is no longer at that place and the rough surface causes vibration to that tire. This vibration may cause your vehicle to slightly pull to the side of the worn bearing.
Yous may also experience your car pulling to the side when applying your brakes. While this is a typical symptom of bad brake rotors or calipers, the actual cause may be the bike bearings themselves because of the excessive corporeality of runout which they crusade.
#five – Excess Wobble or Play in Wheels
This i is a bit trickier to diagnose since you need to have your machine on a hydraulic lift or both wheels of an beam up on jack stands. When lifted, grab one of the wheels and try rocking it back and forth and discover how much "play" or move the bicycle has. Now echo this on the wheel at the other end of the axle.
If the bicycle wobbles or moves back and forth when you lot stone it, you probable have bad bike bearings. Skilful bicycle bearings mean the wheel has almost no wobble or excess play.

Average Cost to Supervene upon Front, Rear, and Hub Cycle Bearings
Forepart Wheel Bearings
Both Sides
Front bicycle bearings are built into the steering knuckle arm associates and connected to drive axle components of your vehicle. These bearings are made to concluding for many years without needing to be replaced. The cost to replace both front end wheel bearings is going to be between $260 and $480.
The parts lonely for the forepart wheel bearings are about $120 to $200. Nonetheless, the labor costs will be a bit more extensive at effectually $140 to $280. The exact cost will depend on the prices of your local repair shop and the make and model of your vehicle. For large trucks, sports cars, and luxury cars, expect to pay more than.
Ane Side
Now if you are just replacing the wheel bearing in ane of your front wheels, these costs will pretty much be split in half. For the total price, on average, expect to pay effectually $130 to $220. The parts volition cost betwixt $60 and $100, and the labor will cost between $seventy and $140.
Rear Wheel Bearings
Both Sides
As for the rear wheel bearings, they will be a tad cheaper to supercede but this will of course depend on the motorcar make and model. The cost of a complete rear cycle bearing replacement volition be somewhere in surface area of $240 to $460.
Parts volition on average be between $100 and $180. The labor costs will exist effectually $140 to $280.
One Side
If yous are simply going to replace one of the rear wheel bearings and then information technology will exist about $120 to $240 for the consummate chore. $50 to $90 for the parts and $70 to $140 for the labor.
Again, these are all simply estimates but they are a adept indicator of what you can expect to pay. The good news is that bicycle bearings take a lot of fourth dimension to wear out and then y'all won't have to replace them very often.
Rear Hub Bearings
Some vehicles employ a rear hub bearing assembly where the cycle bearings are prepacked in the hub and installed every bit a complete unit. Instead of simply replacing the bicycle bearings, the entire hub assembly must be replaced.
This of grade makes the hub assembly more expensive than just the hub bearings. Await to pay on boilerplate between $400 to $800 to replace hub assemblies on both sides of the axle. The toll of parts can vary quite a fleck depending on how avant-garde the associates is but the labor is usually slightly less than a typical rear bearing replacement.
Mutual Types of Bicycle Bearings
Friction is created when a wheel is turned. In that location is more than resistance when the bicycle has a heavy bearing. That is why "wheel bearing" refers to the component which is responsible for reducing the friction that exists betwixt parts while the cycle is spinning.
When the bike's moving parts have less resistance betwixt them, it reduces the wear and erosion that forms. Equally a result, the bicycle'southward lifespan is prolonged.
At that place are dissimilar types of bicycle bearings that a manufacturer can use. Here are some common types along with their main purpose.
Brawl Bearings
Out of all the wheel bearings out there, ball bearings are the most common and well-nigh versatile bicycle bearings that tin be used. They are able to absorb thrust loads and radial loads.
Cornering force per unit area is the thrust load and the weight amount placed on the wheel is the radial load. You volition observe ball bearings in wheels of all sizes, from roller skate wheels to motorcar wheels.
Precision Ball Bearings
The design of precision brawl bearings makes them suitable for high functioning usage. Precision ball bearings have the ability to minimize friction which in plow reduces the corporeality of heat created.
The speed of their rotation is generally higher than regular bearings. For all these reasons, the landing wheels of an airplane and various racing cars accept precision brawl bearings in them. These bearings are designed specifically for extensive thrust and radial loads.
Roller Bearings
Roller bearings are a blazon of bicycle bearings that are used commonly. The simply thing is that roller bearings are not as versatile every bit ball bearings. Roller bearings are skillful at treatment weight but they're not the greatest for cornering.
If you're using wheels which must corner at medium to high levels of speed, and then roller bearings won't be suitable for them. But if yous're using vehicles like grocery carts or mitt trucks, so roller bearings will be fine for them.
Tapered Roller Bearings
The regular wheels of cars and trucks will usually accept tapered roller bearings in them. They have a cone shape which cuts downwardly the friction while cornering every bit the thrust load is high.
Equally you plow the machine, at that place are various degrees to the angle of the wheels. With tapered roller bearings, they prevent grinding in the parts that are shifting.
