Wheel Bearing Maintenance
Bad Bearings: A Problem You Shouldn't Ignore
Your wheel bearings have a massive responsibility. They are engineered to support the vehicle’s entire weight and allow a car’s wheels to turn freely with minimum friction.
The bearings are tightly packed in a grease-filled, waterproof, sealed metal ring. This housing, called a race, and is located inside the hub, and each wheel has one.
There is no maintenance schedule for them, and theoretically they are designed to last the life of the vehicle. But when they don’t, they are a big problem that you don’t want to ignore.
We have found that more often that not, a wheel bearing gets bad so gradually over time, that the driver often gets accustomed to the signs, causing very little to no warning of bearing failure.
Things to Look For:
The most easily identifiable and common symptom of bad wheel bearings is audible.
- - It's more pronounced at higher speeds.
- It can get louder or quieter when the vehicle changes direction, for example, when merging or exiting the highway.
- It can be confusing. For example, the source of a humming noise could instead be linked to other issues, such as
tires and the CV joint.
