Wheel bearings are components that make it possible for the wheels on your car to spin freely and with the least amount of resistance possible. A wheel bearing is a group of steel balls that are kept together inside the hub of the wheel in a race made of metal. While driving, if you hear a humming or moaning noise, one of your car’s wheel bearings is probably beginning to fail.
Although it requires certain specialized mechanic gear, changing your own wheel bearings is regarded as an intermediate task that may be completed at home.
The generalized instructions provided here address the three most typical wheel bearing types that are present on the majority of automobiles. Before you start the repair, make sure to get the service manual for your car and figure out what kind of wheel bearings it has.

Front wheel bearing replacement is it challenging?
If you have the right knowledge, equipment, and manual, replacing a wheel bearing that comes as an assembly with the hub and bolts to the spindle or steering knuckle is not that difficult. The huge axle nut is obviously extremely tight and can be challenging to remove.
If you replace a wheel bearing, do you then need an alignment?
Yes, if you remove the knuckle’s bolt, alignment is required. You can press the bearing in or out with the proper tool if you separate the ball joint and remove the axle from the knuckle.
When changing a wheel bearing, how long does it take a mechanic?
Depending on the complexity and type of vehicle, replacing a single wheel bearing can take 90 to 120 minutes. To carry out this kind of work, several moving parts must be maintained and properly sealed.
Can I simply swap out the wheel bearing and leave the hub alone?
Your wheel bearing may have previously sustained minor damage but is now worn to the point that it is beginning to create noise. Your mechanic is correct in saying that the hub replacement is the only way to fix the bearing. Due to its sealed nature, it cannot be disassembled without being obliterated.
How durable are Toyota wheel bearings?
Wheel bearings can wear out and break even though they are designed to last the whole lifetime of your car. Wheel bearings typically need to be replaced after 85,000 to 100,000 kilometers. Wheel bearings can last a long time in some cars, but they can also wear out very fast in other cars. Your wheel bearings’ level of quality and your typical driving circumstances will determine everything.
Given their location on the wheel, wheel bearings must be able to survive challenging road and weather conditions like potholes, speed bumps, rain, dust, and more. All of these challenging circumstances might shorten their lifespan, so rather than depending on a timeline, you should keep an eye out for the signs of a failing wheel bearing.
How quickly may a wheel bearing fail?
The component that joins the wheel to the axle, known as the wheel assembly, is the wheel bearing. A metal ring holds a group of steel balls (ball bearings) or taper (tapered bearings) together. It makes it possible for the wheel to spin easily and with little resistance. Wheel bearings must be replaced when they cease functioning properly since they are safety-critical parts created to withstand radial and axial stresses brought on by gravity, accelerating, breaking, and cornering forces.
How long does a wheel bearing last?
The typical life of a wheel bearing is 136,000 to 160,000 kilometers (approximately 85,000 to 100,000 miles). This is merely a generalization; the actual lifespan of a wheel bearing is dependent on the bearing’s quality and the environment in which it operates.
Why do wheel bearings fail?
A wheel bearing typically fails for the following reasons:
- Wheel bearing wear can be accelerated by vehicle changes including larger or wider rims, tires with thinner thread walls, stiffer shock absorbers, and suspension springs. To reduce the effect on the durability of the wheel bearings, stick to the rims, tires, shock absorbers, and springs recommended by the automobile manufacturer.
- incorrect installation
- Inappropriate instruments, like a hammer or an impact wrench, can damage the wheel end bearing’s inside and/or exterior, leading to the wheel bearing’s early failure. Additionally, reusing old accessories like bolts, nuts, circlips, split pins, seals, etc. rather than replacing them with new ones can result in the wheel end bearing operating under abnormal or unsafe conditions, causing increased wear on the wheel end bearing and an increase in the risk of an auto accident.
- driving circumstances
- You run the risk of your wheel bearings failing if you drive through mud or deep water. If the seals are broken, water, dirt, or other impurities like dust or salt can enter the bearing, contaminating the grease and destroying the bearings.
- defective wheel bearings Wheel bearings experience constant, intense pressure. Poor heat treatment on wheel bearings made of low-quality materials can lead to early wear and failure.
- Impact harm or inadequate road conditions
- Any contact, like going over speed bumps, hitting curbstones, or driving through potholes, can harm a wheel bearing and shorten its life.
What equipment do I require to replace a wheel bearing?
How Do I Replace a Wheel Bearing? What Equipment Do I Need?
- a pair of pliers with needle-noses.
- ratchet wrench and a range of socket sizes.
- screwdriver with a flat head.
- jack.
- wheel nut removing with a star wrench.
How much does a Toyota Camry wheel bearing cost?
Estimated cost to replace the wheel bearings on a Toyota Camry. Replacement wheel bearings for a Toyota Camry typically cost between $248 and $390. The cost of labor is expected to be between $192 and $242, whereas the cost of parts is between $56 and $149.
Humming Noises
It’s crucial to distinguish between distinct sounds coming from a car because there are several that should raise red flags and prevent incorrect diagnoses. Noise can be deceiving because it might indicate a number of various problems, starting with your tires but also including the wheel bearing or CV joint.
Squealing & Growling
A faulty wheel bearing will typically make a cyclical chirping, squealing, or growling noise. If the sound fluctuates proportionally to the speed of the vehicle, this is another sign that it is caused by the wheel bearings. At any given moment, the sound could suddenly stop or it could get progressively worse.
Rear Differential Noise vs Wheel Bearing Noise
A howling sound that only happens when accelerating is a pretty good sign that the pinion bearing preload is loose. If the howling occurs when accelerating at various speeds, worn-out gears are most likely to blame. However, when they don’t support the gears properly, excessively worn out bearings also have a tendency to howl. When rotating, they frequently emit a rumbling sound.
What would happen if a wheel bearing broke while you were driving?
The noise that a failing wheel bearing will create is the most frequent and obvious symptom of the problem. You should take your car to your mechanic to have the wheel bearings checked if you notice a growling, rumbling, humming, screeching, or squealing sound that gets louder or disappears as you adjust your driving pace.
Have your wheel bearings and shocks/struts examined if you frequently rotate your tires but there is still noticeably uneven wear on them.
If your wheel bearing breaks, the wheel may stop while you are driving or perhaps come off entirely. It’s very important to keep an eye on these and keep them maintained because, at the at least, a failing wheel bearing can/will cause severe damage to your car before a wheel falls off. Do not drive on a wheel if you think the bearings may be failing. Visit your mechanic right away. And if you have any concerns at all concerning your wheel bearings, don’t be afraid to ask your mechanic. They aim to keep you secure and are happy to assist.
How can you distinguish between damaged wheel bearings and defective CV joints?
There’s a strong probability that you have a faulty wheel bearing or CV joint if you hear or feel weird sensations while driving. Finding the source may seem challenging, but there are a few approaches to identify the problematic component.
Listen for the noise to distinguish between a bad wheel bearing and a bad CV joint. A faulty wheel bearing will make a grinding, growling, or rumbling sounds emanating from the affected wheel. A faulty CV joint will make a clicking sound when the affected wheel is turned.
What does it cost to press a wheel bearing?
The national average for replacing one wheel’s wheel bearings is roughly $350. But as you might expect, luxury brands are more expensive. Please note: You don’t necessarily need to repair the bearings at the other wheel on the same axle if the bearings at one wheel need to be replaced.
Should wheel bearings be pressed?
Hello – No pressing is necessary if you replace the wheel bearing/hub assembly. The suggested replacement strategy is this one. Specialized tools are needed and there is a substantial danger of injury while pressing the bearing off or onto the hub. I would advise having a mobile, qualified mechanic, like one from YourMechanic, replace your wheel bearing and hub. They will come to your location, identify the issue, and provide you with an exact assessment of the damage and a repair cost estimate.
How much should new front wheel bearings cost?
Rear-Wheel Bearings
Standard Cone or Roller These bearings are less expensive to acquire, can be changed simply, and typically cost $6 to $20 per unit. Servicing them often costs $80 to $100, plus the cost of replacing the rotor because the bearing race is pressed in.
What is the definition of alignment?
1: the act of aligning or condition of being aligned, particularly: the correct positioning or state of adjustment of elements (as of a mechanical or electrical device) with respect to one another
3: the ground layout, as opposed to the profile, of a railroad or motorway
New alignments within the political party in regard to other groupings or forces in relation to one another.
