A wheel bearing of the vehicle  play a crucial role in ensuring a smooth and safe ride. Over time, they wear out, leading to potential safety hazards. In this guide, we’ll cover:

• What is a wheel bearing?
• Symptoms of a bad wheel bearing
• How long do wheel bearings last?
• Wheel bearing replacement cost
• Can you drive with a bad wheel bearing?

What Is a Wheel Bearing?

A wheel bearing is a set of steel balls or rollers enclosed in a metal ring (race) that allows your wheels to spin smoothly with minimal friction. They support the vehicle’s weight while reducing rolling resistance.

Most modern cars use sealed wheel hub assemblies, while older vehicles may have serviceable bearings that require repacking with grease.

Signs of a Bad Wheel Bearing

A failing wheel bearing can cause several noticeable symptoms:

1. Humming or Grinding Noise – A loud, continuous noise that increases with speed.
2. Uneven Tire Wear – Excessive wear on one side due to misalignment.
3. Steering Wheel Vibration – Wobbling or shaking, especially at higher speeds.
4. ABS Malfunction – Faulty bearings can interfere with wheel speed sensors.
5. Looseness in the Wheel – Excessive play when jacked up and shaken.

How Long Do Wheel Bearings Last?

Most wheel bearings last between 85,000 to 150,000 miles, but factors like driving conditions (potholes, water exposure) and maintenance affect longevity.

Wheel Bearing Replacement Cost

The wheel bearing replacement cost varies by vehicle:

• Parts: $50 – $250 (per wheel)
• Labor: $100 – $300 (per wheel)
• Total Cost: $150 – $550 per wheel

Luxury and 4WD vehicles may cost more due to complex hub assemblies.

Can You Drive with a Bad Wheel Bearing?

Driving with a failing wheel bearing is risky. Severe damage can cause:

• Wheel seizure (loss of control)
• Damage to the hub, CV joint, or axle
• Increased tire wear

If you hear grinding or humming, get it checked immediately.

DIY Wheel Bearing Replacement: Is It Possible?

Replacing a wheel bearing requires specialized tools (press, torque wrench). While some DIYers attempt it, most opt for professional service to ensure safety.

Final Thoughts

A failing wheel bearing is a serious issue that shouldn’t be ignored. If you notice unusual noises or vibrations, visit a trusted mechanic for inspection. Early replacement prevents costly repairs and keeps you safe on the road.
