A Toyota Camry’s rear wheel bearing is changed by swapping out the wheel bearing and hub collectively. Compared to earlier models with two piece wheel bearings, this is a design change. Scottish drive wheels. Delete the back wheel. Rear brake drum removal. (Note: You cannot remove the brake drum when the emergency brakes are engaged.) Remove the hub holding nut and dust cap. Hub should come off in one piece. swap off the hub for a new one. Removing is reversed during installation.

Are rear wheel bearing replacements 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.
Can I change my own wheel bearings?
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.
How long does it take to replace the bearing in the rear wheel?
According to our research, replacing a wheel bearing takes an average of 1 to 2 hours.
The time it takes to replace a wheel bearing might vary significantly from car to car because wheel bearing components can be very different between different automobile makes and models.
Depending on whether the bearing is on the front or back wheel, the time required to replace a wheel bearing also varies slightly. Rear wheel bearing replacements typically take under an hour, whereas front wheel bearing replacements often take roughly 90 minutes.
How can I tell if the bearings in my rear wheels are damaged?
Top Warning Signs You Should Replace Your Wheel Bearings
- Humming sound The most obvious and typical aural sign of damaged wheel bearings is present.
- Growling and Squealing
- a clicking noise.
- Wheel sways.
- ABS lapse.
- Variable tire wear
- Car moves to one side.
- Vibration of the steering wheel.
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.
Both Sides
The steering knuckle arm assembly includes front wheel bearings that are attached to your car’s drive axle components. The purpose of these bearings is to prevent frequent replacement. It will cost between $260 and $480 to repair the bearings in both the front wheels.
For the front wheel bearings, the parts alone cost between $120 and $200. The labor charges, however, will be somewhat higher, ranging from $140 to $280. The precise cost will vary depending on the make and model of your car and the pricing charged by your neighborhood mechanic. Expect to pay extra for huge trucks, sports cars, and luxury vehicles.
One Side
These costs will roughly be split in half if you are only replacing the wheel bearing in one of your front wheels. Expect to spend, on average, between $130 and $220 for the overall cost. Between $60 and $100 will be spent on parts, and between $70 and $140 will be spent on labor.
The rear wheel bearings will be slightly less expensive to repair, but this will obviously depend on the brand and model of the vehicle. The price range for a full rear wheel bearing replacement is between $240 and $460.
The cost of parts will typically range from $100 to $180. The price of labor will range from $140 to $280.
It will cost between $120 and $240 to finish the task if you are only replacing one of the rear wheel bearings. Parts range from $50 to $90, while labor costs between $70 and $140.
Even though they are all only estimates, these prices provide a reasonable idea of what to expect to pay. The good news is that wheel bearings don’t need to be replaced very frequently because they take a long time to wear out.
Rear Hub Bearings
In some vehicles, the wheel bearings are prepacked in the hub and installed as a whole unit. This is known as a rear hub bearing assembly. It is necessary to replace the entire hub assembly rather than just the wheel bearings.
Of course, this raises the cost of the hub assembly relative to simply the hub bearings. For new hub assemblies on both sides of the axle, budget $400 to $800 on average. Depending on how complex the assembly is, the cost of the parts might vary significantly, although labor costs are typically slightly lower than for a standard rear bearing repair.
How do wheel bearings work?
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.
- 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.
- 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.
What distinguishes a wheel bearing from a hub bearing?
Hub and wheel bearings are the two different types. Both have bearing spheres that are lubricated for spinning to enable the wheel to rotate, and as a result, they both utilise the same physical properties of a bearing. The way the two are put together is one of their main differences. Wheel bearings may be disassembled, oiled, and then put back together to be utilized once again. Hub bearings are marketed and installed as a whole unit after being pre-packaged at the manufacturer’s plant. These must be replaced rather than being disassembled for relubrication.
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.
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.
Should both wheel bearings be changed when one is replaced?
1 – If there are two things, replace the good one and worry about the bad one when it happens.
2. Taking into account the mileage and age, if one is terrible, the other isn’t far behind. To save time, replace both at the same time.
Neither perspective is incorrect. Some follow #1, while others follow #2. As someone who has worked on cars for decades, I always choose option #2 when it comes to my personal vehicles. Why ? I accumulated 250,000 miles and 15 years with my 1986 Jetta. No matter if they were “good” or not, I replaced the water pump, thermostat, belts, hoses, cam and crank seals, plugs, cap, rotor, and wires whenever I changed the timing belt, which was every 60,000 miles. My 30-year-old friend used to make fun of how “overkill” my car collection was. He pays for Option #1. He once had to save me from a three-foot snowdrift. I can’t remember how many times I’ve come to his rescue after he broke down on the side of the road.
