Wheel Bearing

Reduces friction between the stationary suspension components and the spinning wheel hub, allowing the wheels to rotate smoothly while supporting the vehicle's weight and cornering forces.

Overview

Wheel bearings allow your wheels to spin freely with minimal friction. Modern cars use sealed hub assemblies that contain the bearing, hub, and often the ABS sensor in one unit.

Parts Cost

$50 – $200 per wheel (hub assembly)

Labor Cost

$100 – $300 per wheel

Failure Symptoms

Humming or growling noise that increases with speed

Moderate

Noise changes when turning (louder one direction, quieter other)

Moderate

ABS warning light

Moderate

Vibration in steering wheel or vehicle

Moderate

Wheel feels loose or has play

High

Uneven tire wear

Moderate

Warning Signs to Watch

Humming noise that increases with vehicle speed
ABS light on dashboard
Noise changes pitch when turning
Grabbing or looseness when wiggling the wheel (with car jacked up)

Common Causes of Failure

1Normal wear from road use
2Water and salt intrusion past seals
3Impact damage from potholes or curb strikes
4Improper installation or over-torquing of axle nut
5Driving through deep water

Prevention Tips

Avoid deep puddles and driving through standing water when possible
Avoid hitting curbs and potholes
Ensure lug nuts are torqued to spec — over-tightening can damage bearings
Fix suspension issues promptly — worn components put extra stress on bearings

When to Replace

Replace as soon as diagnosed. A failing wheel bearing is a safety concern that will only get worse. Most shops can diagnose it on a test drive.

Wheel Bearing by Make

Subaru

Subaru wheel bearings are a known weak point, especially on older Imprezas and Foresters. They often need replacement by 80,000 miles. Budget $200-$450 per wheel.

Chevrolet

GMC

GM trucks and SUVs use hub assemblies that include the ABS sensor. Replacement is straightforward but costs $200-$400 per wheel.

Toyota

Toyota wheel bearings are exceptionally long-lasting. It's unusual for them to fail before 150,000 miles.
