A humming or growling noise that rises with road speed and changes when you swerve is a wheel bearing, and it is one of the most common suspension repairs on vehicles over 80,000 miles. What the job costs depends mostly on one thing: whether your vehicle uses a bolt-on hub assembly or a pressed-in bearing.
Hub assembly or pressed bearing
Most trucks, SUVs and many cars built after 2000 use a sealed hub assembly: the bearing, hub flange and often the ABS sensor in one unit that bolts to the knuckle. It is a straightforward job and the part is the bulk of the cost. Many front-drive cars and some rear axles use a bearing pressed into the knuckle, which needs a press and more labor, so the part is cheap and the labor is not.
Telling the bearing from the tire
A bearing hum changes when you load it: swerve gently left and right at speed and the noise gets louder in one direction. Tire noise stays constant. A bad bearing also shows as play when you rock the wheel at twelve and six o'clock with the vehicle lifted, and on ABS-equipped vehicles a failing hub bearing often sets a wheel speed sensor code first, because the sensor sits in the hub.
What decides the price
The part: a hub assembly for a half-ton truck with the ABS sensor built in costs more than a pressed bearing for a small car. The labor: bolt-on hubs take about an hour; pressed bearings take longer and need the press. And rust: on trucks from the salt belt, a hub seized to the knuckle can double the labor. Four-wheel-drive front hubs are the most expensive combination.
Quality matters more here than on most parts
Cheap hub assemblies fail early and take the ABS sensor with them, so the job gets done twice. We quote established brands and, on vehicles known for it, the OEM hub. The ABS sensor should be included with the hub on vehicles that have it in the hub; check the quote.

Questions we get about this
For a short time at moderate speed, but a bearing that is growling can seize or let the wheel wobble. Treat it as a this-week repair, not a someday one.
Not necessarily. Bearings fail individually. If the other side is original and the vehicle is high mileage, some owners do both to avoid a second visit, but it is not required.
On most vehicles that have the sensor in the hub, yes. We confirm on the quote, because a hub without the sensor on a vehicle that needs it is a common mistake.
