A failing wheel bearing is one of the most common noise complaints on higher-mileage cars — and one you shouldn't drive on for long. Here's how to spot it.

The 5 symptoms

• A hum, growl, or roar that gets louder with speed and changes when you turn left vs right.

• Play at the wheel — jack it up, grab the tire at 12 and 6, and rock it. Any knock or movement is bad.

• Uneven or scalloped tire wear on one corner.

• ABS or traction light on — the wheel speed sensor often rides in the bearing.

• A slight pull or vague steering feel as the bearing wears.

How to confirm

Drive a quiet road at 40-50 mph and gently weave. If the noise loudens when weight shifts onto one side, that's the bearing on the opposite side. Also spin each wheel by hand off the ground and listen for grinding.

Don't wait

A worn bearing can seize or let the wheel wobble badly. Replace it once confirmed. Shop parts and tools at https://www.humbl.online

Frequently Asked Questions

What does a bad wheel bearing sound like?

A hum, growl, or roar that gets louder with speed and changes as you turn left versus right, usually louder when weight shifts onto the side opposite the bad bearing.

How do I check a wheel bearing?

Jack up the wheel, grab the tire at 12 and 6 o'clock and rock it; any knock or play is bad. Spin the wheel by hand and listen for grinding. On the road, weave gently at 40 to 50 mph and note whether the noise grows when weight shifts to one side.

What are the symptoms of a failing wheel bearing?

Speed-dependent humming or growling, play when you rock the tire, uneven or scalloped tire wear on one corner, an ABS or traction light because the wheel speed sensor often sits in the bearing, and a slight pull or vague steering feel.

Can I keep driving with a bad wheel bearing?

Not for long. A worn bearing can seize or let the wheel wobble badly. Once you have confirmed it, replace it.
