Both wheel bearings have racked up the same number of miles, so it's logical to conclude that both sides have probably experienced the same amount of wear. Based on this line of thinking, it would make sense to recommend replacing both wheel bearing hubs at the same time even though only one has obviously failed.
Should I replace both front wheel bearings at the same time?
1 - If one is bad and one is good, replace the bad one and worry about the "good" one when it goes "bad". 2 - Considering the age and mileage, if one is bad, the other isn't far behind. Replace both while you're at it to save time.
How often should wheel hubs be replaced?
Most serviceable wheel bearings need maintenance every 25,000 to 30,000 miles, or during every brake service. But, the average life of a sealed wheel bearing and hub assembly is about 85,000 to 100,000 miles, without the opportunity for a technician to repack the bearings.
How do I know which hub assembly is bad?
Here is a list of signs if you have a hub assembly that may need to be replaced:
- Snapping, clicking or popping noises when cornering or making sharp turns.
- Grinding noise when the vehicle is moving.
- Knocking or clunking sensation from the vehicle.
- Wheel vibration and/or wobble.
- Poor steering control.
Do I need to replace the hub assembly or just the bearing?
Your wheel bearing may have been damaged slightly in the past and has now worn to the point it is starting to make noise. Your mechanic is correct in that the only repair for the bearing is to replace the hub. It is a sealed unit and cannot be disassembled without destroying it.
29 related questions foundHow long can you drive on a bad wheel bearing?
Typically, you shouldn't exceed 1,000 miles on a bad wheel bearing. Driving for distances longer than 1,000 miles could lead to serious complications with your vehicle. Continuing to put stress on this wheel bearing will also hurt the hub, CV joint, and even the transmission.
How much does it cost to replace a hub bearing?
The average cost for wheel bearing replacement is between $265 and $347. Labor costs are estimated between $158 and $200 while parts are priced between $107 and $147. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location. Related repairs may also be needed.
How long will a wheel bearing last once it starts making noise?
To determine how long do wheel bearings last is tough as we mentioned before other factors can play a huge part in determining their durability. However, a wheel bearing can last an average of anywhere from 136,000 to 160,000 km which is about 85,000 to 100,000 miles.
How much does a hub bearing cost?
The vast majority of vehicles today use a complete-unit hub bearing. Here, the cost of the bearing is usually the bulk of the expense, as most hub bearings run between $80.00 to $300.00.
How long does a wheel hub assembly last?
The wheel hub assemblies on a car are intended to last for about 100,000 miles. While this can happen, there are usually things that will happen before this milestone hits that will compromise the assemblies and the way they function.
How long do front hub bearings last?
Although wheel bearings are engineered to last the entire lifespan of your vehicle, they can break and get worn out. Most wheel bearings last about 85,000 to 100,000 miles before they need to be replaced. Some vehicles have wheel bearings that last a lot longer, and some vehicles need them replaced fairly quickly.
Why would a wheel hub need to be replaced?
The bearings reduce the friction in the wheels and allow them to turn smoothly and efficiently. If one of the bearings becomes worn or damaged, all of the hub bearings need to be replaced. In newer cars this usually means the entire wheel hub assembly needs to be replaced, which is actually a relatively simple process.
Should wheel hubs be replaced in pairs?
Even if only one side is bad, it makes sense to replace them in pairs. The “good” side is likely to cause problems in a relatively short time. Also, after driving the car, you can check the temperature of the hub assembly.
How can you tell if your front wheel bearings are bad?
The most common and most easily identifiable symptom of a bad wheel bearing is an audible one. If you notice a grinding or grating noise coming from your wheel or tire, take note that this is very likely caused by a bad wheel bearing—especially if the noise gets louder as the vehicle accelerates.
How long does it take a mechanic to change a wheel bearing?
Replacing a single wheel bearing can take 90 to 120 minutes depending on the type of vehicle and complexity. There are a lot of moving parts that need to be maintained and properly sealed to complete this type of work.
What happens if I don't change my wheel bearing?
Ultimate damage: If you don't replace a damaged wheel bearing before it fails completely, the wheel will completely seize up. If this happens while you're driving, the results can be catastrophic. This is not a component to take chances with.
What causes a loud humming noise while driving?
A bad wheel bearing is one of the more serious issues that cause tire noise. When the wheel bearing in your tires is damaged or deteriorating, it produces a soft humming sound or grinding noise when you change lanes.
How long does it take to replace a front wheel bearing hub assembly?
Factors Influencing Hub Assembly Installation
For new technicians, turnaround time can be up to two hours. However, that time can be cut in half by experienced technicians, especially if there are no delays in acquiring parts or tools.
What is the difference between a hub bearing and a wheel bearing?
A major difference between the two is how they are assembled. Wheel bearings can be taken apart, lubricated and reassembled to be used again. Hub bearings are pre-packed at the manufacturer's factory and are sold and installed as a complete unit. These cannot be taken apart for re-lubrication, but must be replaced.
Is it easy to replace a wheel bearing?
Is it easy to replace a wheel bearing at home? Replacing a wheel bearing that comes as an assembly with the hub and bolts to the spindle or steering knuckle is not very difficult if you have proper skills, tools and the manual. Of course, the large axle nut is very tight and can be difficult to remove.
Can you drive 500 miles on a bad wheel bearing?
Try not to exceed 500 miles or 800 kilometers when you get the first sign of a bad wheel bearing, even if has that estimated lifespan, especially if you do not know what you bearing you have there. A failing wheel bearing will cause the vehicle to lose control, making it difficult to drive.
Can I drive 200 miles with a bad wheel bearing?
If the bearing noise has been growing gradually, then without suggesting it is "okay" to drive 200 miles, the noise may just grow worse over that distance. If the bearing noise appeared out of nowhere, then that suggests an immediate failure potential and should be changed BEFORE a 200 mile drive.
Is it OK to drive with a noisy wheel bearing?
It is safe to drive with a bad wheel bearing only if you just started to hear a humming, whining, grinding, or growling sound coming from the front or rear wheels. This indicates that the wheel bearing has begun failing and you would need to replace it as soon as possible.
Do you have to grease hub assembly?
Hub assemblies can be oiled or greased, and just like motors and transmissions, the lubricant and lubrication practices will have a considerable impact on their life expectancy and operation. The better you take care of these components, the longer they will last.
