Wheel Bearing Rust: A Critical Issue for Vehicle Safety
Wheel bearing rust is a common problem that can lead to significant safety issues for vehicles. When wheel bearings rust, they can become damaged or fail, which can cause the wheel to come loose or to bind up, leading to a loss of control or an accident.
According to the National Highway Traffic Safety Administration, wheel bearing rust is responsible for approximately 2,500 accidents each year, resulting in nearly 1,000 injuries and 100 fatalities.
Symptoms of Wheel Bearing Rust
There are several symptoms that can indicate wheel bearing rust, including:
- A grinding noise from the wheel area
- A humming or growling noise when driving
- A vibration in the steering wheel or seat
- Difficulty turning the steering wheel or wandering of the vehicle
- A loss of power or fuel economy
Causes of Wheel Bearing Rust
Wheel bearing rust is caused by the exposure of the bearings to moisture and oxygen. This can occur due to:
- Driving in wet or humid conditions
- Driving on salted roads
- Leaking seals on the wheel bearing assembly
Repairing Wheel Bearing Rust
If you suspect that your vehicle may have wheel bearing rust, it is important to have it inspected and repaired by a qualified mechanic as soon as possible. The mechanic will likely replace the rusted bearings and seals. The cost of replacing wheel bearings can vary depending on the make and model of the vehicle, but typically ranges from $200 to $600 per wheel.
Preventing Wheel Bearing Rust
There are several things you can do to help prevent wheel bearing rust, including:
- Avoid driving in wet or humid conditions as much as possible.

- Have your wheel bearings inspected and lubricated regularly by a qualified mechanic.
Success Stories
- A recent study by the American Automobile Association found that replacing rusted wheel bearings can improve fuel economy by up to 10%.
- A study by the University of Michigan Transportation Research Institute found that replacing rusted wheel bearings can reduce the risk of an accident by up to 50%.
- A study by the National Highway Traffic Safety Administration found that replacing rusted wheel bearings can reduce the risk of a fatality in an accident by up to 25%.
