There is no set mileage. You replace them when they wear out which may never happen. They normally last the life of the car.
Wheel bearings typically last between 85,000 to 100,000 miles, but their lifespan can vary based on factors such as driving conditions, maintenance, and the quality of the bearings themselves. Regular inspections and proper lubrication can extend their life. Signs of wear, like noise or vibration, should prompt immediate attention to avoid further damage.
Bearings on Inifinitis should be replaced after every 30,000 km. If not, they can start grinding with or without noise. If you drive in this fashion for a while, you risk losing a wheel.
It could seize up next time you drive it. Don't take chances, replace faulty wheel bearings immediately.
You can't. The bearings and the hub are assembled as one and expected to last the life of the vehicle. When the hub/bearings do fail, the assembly is replaced as one unit.
The wheel bearings are sealed and should last a long time. If you think they are bad you would have to replace the bearings they cannot be repacked.
It depends on the vehicle. Most vehicles built in the last twenty years have sealed bearings.
For all kinds of things. Better gas mileage, better tire life, so your car goes straight, so your wheel bearings last longer.
1.) Depends on the driving conditions, driving through water or salted roads. 2.) Depends on whether or not it was lubricated. Some wheel bearings are sealed so you can't lube them if you want to. 3.) Synthetic grease would make them last longer than if lubed with petroleum based grease.
i had mine done last year in Canada and it was ~$400 for the bearing (just one) and ~$200 for the labor
If the wheel that fell off was the same corner as the replaced bearing the lug nuts we're probably loose. If you have alloys, corrosion on the inside of the wheel where it bolts up can cause this.
Your question isn't clear. The seals usually last the life of rotor or bearings inside and are not a maintenance item for replacement. generally they are only removed when replacing bearings or installing a new rotor and even then, if careful often can be reused.
